Product details

What it is and what it does

The Festo SIEF-M12B-PS-S-L is an inductive proximity sensor from the SIEF series, classified as a Proximity Detection Switch under Inductive Sensors. It detects metallic objects without physical contact, making it a standard choice for position sensing in pneumatic actuators, valve islands, and automated assembly stations.

Frequently asked questions

Will SIEF-M12B-PS-S-L drop into a panel that was specified around SIEF-M12NB-PS-S-L without rewiring?

Mechanically yes — the SIEF-M12NB-PS-S-L shares the same M12 barrel and connector. The difference is the output function (normally closed vs normally open), so verify the logic before installing. No rewiring needed if the output matches.
