ComEx Potentiometer

Rail-mounted installation for Zone 1
  • easy and exact setting of the desired value
  • Easy installation
  • High IP rating


The ComEx potentiometer is used in virtually all hazardous (potentially explosive) locations where machine functions are controlled by means of adjustable voltage distributors. The module can be combined with a potentiometer actuator (scale graduation 0 to 10). Conductors are connected via of terminals on the back of
the module which have an increased safety level. The easy installation of the potentiometer actuating element without the need for the use of tools ensures conformance to the high IP degree of protection.
