7-3-3 Connector pin assignments
The sensor is connected by means of a standard 5-pole M12 connector. The pin assignment is depicted
below with the view of connector pins on the sensor.
7-4 Connection in line with EMC requirements
To ensure stable functioning of the sensor the following precautions should be considered:
•
In environments with high interference levels, use cables with twisted-pair wires and/or shielded cables.
•
When cables are introduced into an EMC control cabinet, guide the cable shield without interruption
through the wall of the EMC control cabinet (e.g. via a cable conduit).
•
Professionally connect the cable shield to the control cabinet housing (flat surface, conductive).
•
Professionally connect wires of cables or free cable ends that are not used to the cable shield on both
ends of the cable.
•
If the control cabinet is connected by means of connectors, use connectors with a metal housing and a
leading protective earth contact (in accordance with EN 60204-1) only.
•
Conductively connect the cable shield to the connector housing.
•
Professionally connect the mating connector to the control cabinet housing (flat surface, conductive).
•
Route supply and signal leads in separate cable ducts.
•
Route supply and signal leads as closely as possible to the equipotential bonding conductor.
•
Do not route cable ducts in the proximity of strong electromagnetic interference sources such as electric
motors or transformers.
•
Suitable protective measures conforming to EN 60204-1 must be taken if the cable layout does not fully
rule out the risk of lightning strikes.
