Industrial inductive sensor
The Turck BC5-S18-AN4X 25031 is a flush-mount inductive proximity sensor with an M18 × 1 threaded barrel. It provides a rated switching distance of 5 mm and uses a DC 3-wire NPN normally-open output. The housing is moulded from PA12-GF30 plastic with a PEI sensing face. A cable tail supplies the electrical connection.
Upgrade from basic limit switches
This sensor replaces mechanical limit switches or lower-spec inductive units that lack fine adjustment. The built-in potentiometer allows precise setting of the switching point without shims. The jump is worthwhile when an application demands non-contact detection of metal targets at 5 mm with a wide 10…65 VDC supply range and solid-state reliability.
Sustained operation behaviour
Under continuous duty the sensor maintains its 5 mm switching threshold across the full 10…65 VDC window. The PA12-GF30 barrel resists oils, coolants and mechanical shock without degradation. NPN output switching remains consistent without contact bounce or wear, and the 110 g weight adds minimal mass to moving fixtures.

Questions about this item
What thread size and housing material does the M18 sensor use for mounting?
The sensor has an M18 × 1 threaded barrel made from PA12-GF30 plastic, suitable for standard M18 mounting holes.
How is the switching distance set, and what mistake should be avoided?
Adjust the 5 mm rated switching distance using the built-in potentiometer; do not exceed the 10…65 VDC supply range while calibrating.
Which cable and output type will need checking or replacement over time?
The fixed cable carries a DC 3-wire NPN NO output; inspect the cable jacket and connections periodically for wear.
