Product details

The Festo SIEH-M12B-PS-K-L is an inductive proximity sensor in the standard M12 barrel form factor, with a 4 mm flush sensing range and a PNP normally open switching output. It operates on 10-30 V DC and switches loads up to 200 mA. The nickel-plated brass housing and cable exit make it a straightforward drop-in for pneumatic actuator position feedback or general machine presence detection in a control cabinet.

Frequently asked questions

What is the closest functional second-source to SIEH-M12B-PS-K-L?

The SIEN-6,5B-PS-K-L is a peer inductive proximity sensor with the same PNP normally open output, 200 mA rating, and 10-30 V DC supply, but it has a 6.5 mm barrel and a 1.5 mm sensing range — not a direct mechanical or range swap for the M12 4 mm sensor.

Will SIEH-M12B-PS-K-L drop into a panel specified around SIEN-6,5B-PS-K-L without rewiring?

The electrical wiring is identical — both are PNP normally open, 10-30 V DC, 200 mA — but the M12 barrel (12 mm diameter) requires a larger mounting hole than the 6.5 mm sensor, and the 4 mm sensing range is longer, so the target spacing may need adjustment. The cable connector type is the same.
