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 technology brings benefits for the customer
Green engineering is part of the GEMÜ range. The future-oriented company philosophy immediately brings customers twofold economic advantages: by means of competitive pricing in purchasing, but also in assembly and the range of functions. 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. Furthermore, 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.
Large range of functions
Moreover, GEMÜ 4242 integrates functions that render other accessories superfluous. 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.
System solutions for complex procedures and processes
The robust housing has been solidly built to meet ATEX requirements, and it has a transparent cover. Travel sensors, switching valves and status LEDs have been integrated into the housing. The connection is made using a standard M12 connector. In addition to discrete switching and feedback, there are field bus connections for the AS interface, DeviceNet and also the option to connect using the IO link communication interface. The combi switchbox can be used in most industrial sectors and process plants for local activation of valves. GEMÜ provides system solutions for complex procedures and processes. In such situations, the 4242 combi switchbox sets the standards, thanks to its intelligent position sensor with integrated travel sensor system and the high visibility position indicator.
