Description
The ComEx
flex
potentiometer, type 07-3373-4***/****, is used
in almost all hazardous (potentially explosive) areas where
machine functions are controlled by means of adjustable voltage
distributors.
The ComEx
flex
potentiometer can be combined with a
potentiometer actuator (scale graduation 0 to 10). A junction
box is available as a safe and convenient means of installing the
potentiometer in a control panel.
The conductors are connected by means of terminals on the back
of the ComEx
flex
potentiometer which have an increased safety
level. The easy installation of the potentiometer actuating element
without the need for tools ensures conformance to the high IP
degree of protection.
