Connector pin assignments

The sensor is connected by means of a standard 5-pole M12 connector

(see

Figure 5 Connector pin assignments)

Connection in line with EMC requirements

• In environments with 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 connec-

tors 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 hous-

ing (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 inter-

ference 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.
