Cube67: Decentralization at its best


The Cube system from Murrelektronik is a modular field bus system for on-machine installation concepts. It’s engineered flexibly to be the optimal solution for any application – meeting protection class IP20 through IP69K.

Cube67 features great functionality, easy connections, a robust and compact design, fully molded modules, and multi-functional inputs and outputs. The modules can be installed right next to the sensors and actuators.
Our one-cable-technology connects the modules to the bus node, transferring both data and power. Extensive diagnostics enable maximum transparency. The number of terminals in the control cabinet is reduced by moving field bus modules into the field, freeing up space.

The Cube67 field bus system makes it possible to change bus without changing system: installation concepts can be implemented independent of existing control concepts. Simply select the bus module with the desired field bus protocol; Murrelektronik can provide bus nodes for the most common field bus systems.
Cube67 solutions provide maximum cost-benefit ratio across the entire life cycle of a machine: through simplified design, fast application assembly, error-free commissioning, and maximized system runtime for productive operation.

KEL-DPZ round, grey

Cable entry plates


KEL-DPZ entry plates are designed to route and seal cables without connectors or fibre optics (from 1.5 mm to 22 mm in diameter) in limited space.
The assembly of the KEL-DPZ round with cables or pneumatic hoses can be done quick and easy. Simply make a small hole in the thin membrane, push the cables through. The KEL-DPZ round provides strain relief and protection IP66 / IP68 / UL type 4X.

The round versions of the KEL-DPZ series have a thread to fit in metric cut-outs from M25 to M63.
Thus cut-outs for metric cable glands can be used.
ST-B Plugs can be used for sealing pierced membranes if cables have been removed.

  • Quick and easy tool-free assembly
  • High cable density
  • Automatic sealing and strain relief for the cable
  • Suitable for metric cut-outs
  • Polyamide locknuts are included in the shipment
  • Dual sealing of cables according to IP66 / IP68 / up to UL type 4X

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).
