M8 Flush Inductive Proximity Sensors 1–4 mm

Number of part numbers per output, supply and sensing distance. Each count includes all contacts, connections and housing versions.

“—”: no standard part number; send your requirement for a project evaluation.

1. Distance: choose from 1 / 2 / 3 / 4 mm so the target passes well inside the rated distance, not at its limit.
2. Output and supply: PNP or NPN to match the PLC input card; DC 2-wire to replace a mechanical switch in series with the load.
3. Contact: normally open or normally closed, or NO + NC when one sensor must give both signals.
4. Connection and housing: 2 m cable, M8 connector, M12 connector, M8 pigtail, M12 pigtail; short housing where there is little depth behind the bracket.

Mount the sensing face level with the bracket and keep the area in front of the face clear of metal other than the target. IEC 60947-5-2 classifies proximity switches as embeddable (flush) or non-embeddable (non-flush); the minimum clearances for each part number are on its dimension drawing.

1. Clamp the housing with the two lock nuts; do not hammer the housing.
2. Check that no bracket edge, plate or second sensor is inside the clear zone.
3. Power up and move the target into position to confirm the switching point before fixing the cable.
