We opened a new production hall


Since its inception the company Varga Elektronik to this day, we were guided by the pronouncement of the inventor Thomas Edison that success is 1% luck and 99% hard work. The basis for our overall business is based on these foundations.
The company started work in 2005 with only one employee in a garage of a family home and a representation of 6 reputable companies for industrial electronics.

After one year, we started cooperation with the Swiss company ETA SA, a member of the world-renowned SWATCH GROUP. Initially, cooperation was based on the production of empty electrical cabinets. Today, after 13 years of successful co-operation, from the production of empty electromagnetics, we came to the fact that for ETA SA, we do complete Hardware and Software control for machines that are used to manufacture watches.

Apart from making new machines and control for machines, we have been able to compete with strong competitors from Germany and France, for the audit of older machines in the company ETA and several other companies in Switzerland, such as Microdul AG, Eltron Schweiz GmbH, Posalux SA, MSV AG , Jürg Huggler AG and others. This is proof that Varga Elektronik has quality and can compete with the biggest names on the European market.

In 2012, we started building a new facility and new headquarters of our company. So in 2014 we moved to a new space.
During that time period, our company has been recognized by 4 other companies involved in the production of electro-components for industrial electronics and offered their representative office for Croatia and other countries in the region. Today we can proudly say we represent 7 German and 3 Swiss companies that cover 90% of needs in industrial electronics.
As we grow and expand our product range from year to year, we became aware of the fact that we can no longer develop quality and meet the growing needs of our customers and clients at the existing location. Therefore, in 2017, we decided to expand our production capacity so that quality and deadlines could respond to more demanding projects.

A year later, we opened a new production desire of 300 square meters.
Each investment is a sort of risk that the entrepreneur takes on himself and nobody guarantees success. However, there is no development without investment and without any risk, courage and investment in people and technology. Varga Elektronik will continue to invest in employee training and will continue to develop and introduce new products for the next 14 years.
We look forward to new projects that will contribute, not only to the successful production and development of our company, but also to the development of the entire Međimurje region.

Full Inox Chip-Immune inductive sensors


New inductive sensors for metal machining processes

Contrinex announces a new series of Chip-Immune sensors with NPN polarity to complement the existing range of PNP types. As a result, this sensor family is ready not only for metal-machining systems with positive logic (sink current; PNP) but also those with negative logic (source current; NPN).

Machines for turning, milling, drilling or grinding metal will inevitably generate abrasion debris. For inductive sensors, which by their nature detect metal objects, this debris presents a difficult challenge. When sensors are covered with lubricant containing metal chips, there is a risk that they will supply incorrect signals to the control system. For these applications, sensor specialist Contrinex now offers its Chip-Immune series of inductive sensors in M12, M18 or M30 housings for non-embeddable mounting. Even when covered with chips of iron, aluminum, stainless steel, brass, copper or titanium, they will reliably detect targets made of these metals. The sensor achieves this with a slightly modified form of the Condet® method, which operates on the basis of pulsed currents in the coil and uses returned inductive voltage as the useful signal. These sensors have a one-piece stainless steel housing with IP68 and IP69K protection rating and a wide operating temperature range from -25 to +85°C (-13 to +185°F). This makes them particularly suitable for use in the harsh environments of the machining industry. Depending on sensor diameter, operating distances of 3, 5 or 12 mm are available while repeatability ranges from 0.2 to 0.8 mm. The sensors operate at frequencies of 90, 200 or 400 Hz. In the PNP version, sensors also include an I/O-Link interface for communication with the rest of the system.
In practice, the use of these new inductive sensors can save time, money and even help protect the environment. In metal-cutting operations with conventional inductive sensors, reliability is ensured by regularly spraying chips away with water. This is no longer necessary with the chip-immune range of inductive sensors.

Pregled Chip-Immune senzora:

  • Housing M12, M18 or M30
  • Detection not influenced by chips of iron, aluminum, stainless steel, brass, copper or titanium
  • Detects targets made of the above metals
  • Robust: one-piece stainless-steel housing, protection rating IP68 and IP69K
  • Temperature range -25 to +85°C (-13 to +185°F)
  • Operating distance 3, 5 or 12 mm
  • IO-Link

The first DIN rail power supplywith an integrated IO-Link port


The power supply is placed at a central nodal point in the system. There is more than just current flowing. A power supply records a significant amount of real-time information that is of particular interest to the operating firm as well as the system manufacturer.

This data can help increase system availability and reduce maintenance and operating costs. This means the power supply has the potential – in parallel with its function as a converter – to also act as a sensor and therefore make a significant contribution to the Industrial Internet of Things (IIoT).

The DIMENSION QT40.241-B2 sees PULS bringing to market the first 3-phase DIN rail power supply (24V/40A) that makes this system data available to users via an I/O port.

Advantages of IO-Link as a communication protocol


The component requirements for an IO-Link port in the power supply are relatively low when compared to more complex communication protocols. This offers several advantages: thanks to the low number of additional components, the MTBF value (Mean Time Between Failures) of the QT40.241-B2 remains constantly high. The MTBF stands at 678,000 hours and is indicative of the reliability and thus the fault tolerance of the device.


IO-Link was designed as a user-friendly plug-and-play solution. Installation and operation are easily and cost-effectively implemented. The port can be cabled using standard, unshielded IO cables. In addition, compatibility with all standard fieldbus and automation systems is provided, ensuring flexible usage options.


IO-Link is very robust and also offers a high level of safety. Industrial power supplies are often exposed to the harsh environments of the lower automation level and also need to be protected against external manipulation. Data transmission via IO-Link has been field-tested for these applications.

More information on IO-Link

Integration of the QT40 into an existing IO-Link system

IO-Link was designed to retrieve the signals of the sensors and actuators (IO-Link devices) from the field level. Via an IO-Link master, these are fed into the respective fieldbus system and transmitted to the automation system.
The combination of fieldbus and IO-Link thus enables continuous communication across all levels. IO-Link is an open standard that is compatible with all common fieldbus and automation systems. This allows flexible use.
The integration of the QT40.241-B2 into an existing IO-Link system requires only a connection to the IO-Link master. For this purpose, standardized, unshielded IO cables are used. The installation and operation are thus uncomplicated and can be implemented cost-effectively.

MEASURING AND MONITORING with the ComatReleco family of measuring devices


Energy measurement’ is a buzzword today, and a key concern of many professional institutions. That’s fully understandable – because the benefits from the data obtained make a considerable contribution to optimising systems and resources. A precise energy measuring device records and documents energy needs. Targeted initiatives can optimise network loads and decrease operating costs.
Current and voltage monitoring relays are being used not only to protect systems and persons, but also in process management. ComatReleco measuring devices are the perfect support for users’ needs in the field, right up to supervisory and management level.

Base level: MBx devices for everyday use

Efficient assembly plus quick start-up and maximum system availability – these are our prime concerns with this series. The voltage, current and motor temperature monitoring relays of the MBx series are compact and user-friendly. The response threshold is set by means of one potentiometer, and the delay time (notification delay) is determined using another. The easy-to-read, multicoloured status LED on the device ensures that information is displayed clearly. The first device of the series to become available will be the MBU voltage monitoring device.

State level: MRx devices for demanding situations

The much-loved MR series is the established standard in the field of high-quality monitoring relays for voltage, electricity, phase failure and other values in AC and DC circuits. The devices are available in one- and three-phase designs. The one-phase device monitors one measurement variable, while the three-phrase MR allows two measurement variables to be monitored simultaneously and assigned to one of the two separately configurable relay outputs (6A/250V). The status of the measurement variables is displayed on clearly visible LEDs. The contrast-rich display makes for easy reading of the current measurement values. The device is configured using an easy-to-understand menu, which has been designed so that it is impossible to forget any of the many different settings. The user parameters are saved in such a way as to be proof against power cuts. The devices have permanent self-diagnosis systems. This ensures that an alarm is always triggered in the case of a defect.

High level: MRE devices also measure and communicate via fieldbus

The MRE-44S/DC24V is a compact energy-measuring device for high-precision recording of all electrical variables. As a result of the high accuracy grade (current 0.1, voltage 0.05) and numerous features that can be freely enabled – such as an expansion of the grid frequency range from 15 Hz to 400 Hz, a complete power quality analysis and the analysis of harmonics up to 50 kHz – it can be used flexibly for nearly all measuring tasks related to electrical infrastructure in industrial settings as well as office and administrative buildings. The integrated web server allows for the MRE to be configured manageably and in relation to the application with a few clicks. The measuring circuit data are output directly into the SPS or control system via the integrated ethernet interface (TCPI/IP modbus) or RS-485 interface (RTU modbus). The data logger, available as an optional extra, displays the measuring circuit data of several MREs and makes it possible to create long-term analyses and evaluations. A wide range of different transformers is available for current measurement, with various degrees of accuracy and corresponding transformation ratios.

Based on a modern architecture, this device is ideally suited for implementing customer-specific requirements – whether they take the form of integrated user software or expanded fieldbus interfaces.

Werma presents EvoSIGNAL – a modular system to quickly find the right signalling solution


EvoSIGNAL – find the right signalling solution quickly and easily
The purpose of signal devices is to alert, guide and protect. The type of optical and audible signalisation depends on the relevant application and environment. Until now, selecting the appropriate signal device was often challenging and complex owing to the large number of variants available. The latest evolution from the Rietheim-based signalling technology specialist provides an answer to this problem. With Werma’s EvoSIGNAL, finding the right signal device is easier than ever: a clear, modular system optimally covers virtually all application fields. In just a few steps, potential customers are guided to the right product for their requirements – as a result, incorrect purchases and time-consuming return processes are now a thing of the past. This makes EvoSIGNAL the new standard solution in the field of signalling technology – modular, simple and clearly structured.

In future, Werma’s new products, available in three size classes (Mini/Midi/Maxi) in conjunction with optical/audible signalling options and mounting adapters, will cover all areas of application – currently, only EvoSIGNAL can achieve this. The number of versions has been reduced to 20% of the previous range, which means less effort with fewer part numbers. Despite this reduction, Werma’s intelligent combination options now perfectly cover a wide range of applications while simultaneously ensuring full compatibility with predecessor products, for instance in case replacements are necessary.

“In only three steps, the ideal signalling product can be easily found with the help of our QuickFinder or our online configurator. Select the size – choose the type of signalling – select the installation option – and you’re done! This makes selection easy and in future will also prevent incorrect purchases when it comes to choosing the right signalling solution,” explains Michael Groll, Head of Strategic Marketing at Werma Signaltechnik.
“Furthermore, our EvoSIGNAL customers of course also benefit from our "Best-in-class philosophy". Our customers need not compromise on anything in terms of intuitive installation, durability, approvals, audible signals and light effects with twin functions that can also be used for escalation purposes,” adds Winfried Huber, Head of Sales in Germany.

Photoelectric miniature sensor in place of optical fiber Contrinex

In some applications, installation space is so limited that there is no room for photoelectric sensors. So optical fibers are often used, despite their higher installation cost. Now Contrinex has developed a new photoelectric sensor which, due to its extremely small size, offers the ideal alternative.
The sensor specialist has developed a 4 mm diameter or M5 threaded photoelectric sensor that is ideal for use in the robots, grippers, and small conveyors that must detect very small parts, typically in packaging, logistics, assembly and automation applications. All components of the miniature sensor, from the active light source with optics to the evaluation electronics and IO-Link connection, are combined in a robust stainless steel housing. Large, pre-calibrated sensing ranges of 12, 24, 60 or 120 mm for the diffuse type (LTR version) and up to 500 mm for the through-beam type (LLR version) allow easy installation. These miniature photoelectric sensors work with visible red light (630 nm), which simplifies adjustment. The switching frequency of 500 Hz to 2.5 kHz, which can be set via IO-Link, enables the integrated evaluation electronics to detect very small parts, such as wires, with great reliability even at high throughput.

Robust stainless-steel housing

The cylindrical housing in V2A stainless steel is mechanically very robust, has an IP67 protection rating and is suitable for embeddable mounting in both the 4 mm diameter version and the M5 threaded type. Thanks to the advanced focusing technology of its integral optics, the sensor’s light spot has a diameter of just 6 mm at a sensing range of 50 mm, depending on the model. This allows even the smallest parts to be reliably detected. The supply voltage of the miniature photoelectric sensor is in the range 10 to 30 VDC, the connection for power and data is either via a PUR cable or an M8 4-pin connector. Depending on the type of sensor, the weight of these tiny devices is 4, 12 or 30 g for connector, pigtail or cable versions. The permissible operating temperature ranges from -25 to +65°C (-13 to +149°F).
