4.7 External position displacement sensor

WARNING

Versions with flameproof enclosures may not be operated with an external position

detection system.

The aforementioned measures are not adequate in some applications. For example,

continuous and strong vibrations, high or too low ambient temperatures and nuclear

radiation.

The position displacement sensor and the control unit are mounted separately for these

applications. A universal component is available for this purpose. It is suitable for part-turn

and linear actuators. You will require the following:

● An external position detection system with the order number C73451-A430-D78

comprising a positioner enclosure with an integrated friction clutch, potentiometer as well

as different blanking plugs and seals.

● Or a contactless explosion-proof non-contacting position Sensor (e.g.6DR4004-6N).

● A positioner

● A three-pole cable to connect components.

● An EMC filter module with the order number C73451-A430–D23 is provided in a set along

with cable clamps and M20 cable glands.

The EMC filter module is always used for the control unit whenever an external position

sensor is used instead of the external position detection system. An external position sensor

is, e.g. a potentiometer with a 10 kΩ resistance or a non-contacting position sensor.
