5.6.7 Connector and Sensor Cable
Never bend the sensor cable by more than the bending radius of 90 mm.
The sensor comes with a permanently mounted connection cable of 0.25 m in length. A 3 m, 6 m or 9 m sensor cable has to be at-
tached to the connection cable.
MICRO-EPSILON recommends the use of the standard sensor cable in the appendix, see Chap. A 1, with a chain-type cable capabil-
ity.
The connector and the cable component are marked with red markings which have to be aligned opposite each other before connec-
tion. In addition, they come with guidance grooves to prevent them from being wrongly connected. To release the plug-in connection,
hold the plug-in connector on the grooved grips (outer sleeves) and pull apart in a straight line. Pulling on the cable and the lock nut
will only lock the plug-in connector (ODU MINI-SNAP FP - lock) and will not release the connection.
Avoid subjecting the cable to excessive pull force. If a cable of over 5 m in length is used and it hangs vertically without being
secured, make sure that some form of strain-relief is provided close to the connector.
Never twist the connectors in opposite directions to one another when connected.
Connect the cable shield to the potential equalization (PE, protective earth conductor) on the evaluator (control cabinet, PC hous-
ing) and avoid ground loops.
Never lay signal leads next to or together with power cables or pulse-loaded cables (e.g. for drive units and solenoid valves) in a
bundle or in cable ducts. Always use separate ducts.

Disconnect or connect the D-sub connection between RS422 and USB converter, when the sensor is disconnected from power
supply only.
