The new GEMÜ 4242 combi switchbox is suitable for secure and fast applications in most industrial sectors and process plants.

It is small, compact and light, and is ideal for pneumatically operated linear actuators. With its integrated 3/2-way pilot valve made of anodized aluminium or stainless steel, the new combi switchbox 4242 from GEMÜ, the Ingelfingen-based specialist for valves, measurement and control systems, is especially designed for smaller and medium nominal sizes. It is particularly well suited for secure and fast applications with a stroke of 2 to 30 mm.

The design is compact and saves material, and in comparison with competitors' products, it is much smaller. This has a favourable effect on pricing and provides protection for the environment at the same time.

Green engineering is part of the GEMÜ range. The pneumatic and electrical connections of the combi switchbox save 
space and enable easy access as they are positioned in one direction. This means that the combi switchbox can be fitted quickly and easily without any great need for cabling, and there are no problems during servicing either.

Mounting and commissioning is made simpler by a speed-AP function. A manual override enables fast diaphragm change. This all saves time and money, and lowers the planning efforts.

The combi switchbox has a microprocessor-controlled, intelligent position sensor and an analogue, integrated travel sensor system. The combi switchbox provides extended diagnostics, and reports various programming, sensor and pneumatic faults using high visibility.

The end positions are programmed on site via the reed contact, using a solenoid on the top of the housing, but without a PLC connection. The position of the reed contact in the housing is clearly marked. The housing therefore need not be opened. Mechanical openings in the housing for buttons and switches are therefore not required.
