Diagrams
Notes:
1. These diagrams are valid for sensors with cables and connectors.
2. Sensors may or may not have ground connections or grounded
housings. Refer to the specific connector or cable diagram for your
particular sensor’s model number to determine if it is grounded.
3. The markings on these wiring diagrams (L1, Load, etc.) are identical
to those on the connector diagrams.
4. All switches are Normally Opened (N.O.) unless specifically marked
Proximity Sensors
Normally Closed (N.C.).
5. All switch outputs are Sourcing unless specifically marked Sink.
