The new GEMÜ 4242 combi switchbox is suitable for secure and fast applications in most industrial sectors and process plants. Its compact, lightweight design is ideal for pneumatically operated linear actuators. With its integrated 3/2-way pilot valve made of anodized aluminum or stainless steel, the combi switchbox is particularly well suited for secure and fast applications with a stroke of 2 to 30 mm. The combi switchbox has a microprocessor-controlled, intelligent position sensor and an analogue, integrated travel sensor system. It 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.
