The Festo SIEN-M12B-PS-S-L is a flush-mountable inductive proximity sensor with a 2 mm rated operating distance, switching at 3000 Hz. It delivers a PNP normally-open signal through an M12 3-pin connector, rated for 200 mA continuous output current. The brass, nickel-plated housing with PBTP sensing face carries IP65 and IP67 ratings, so it handles washdown and wet environments on packaging or material-handling lines. The 12 mm barrel and 45 mm length fit standard M12 sensor mounting holes. Operating voltage spans 10 to 30 V DC, with a -5 to 70 °C ambient range — typical for machine-mount proximity sensing on conveyors, grippers, and cylinder position detection.

Frequently asked questions
How do I get pricing and availability for the SIEN-M12B-PS-S-L?
Submit an RFQ. This part is sourced through independent distribution — availability and current pricing are confirmed at quote time, not on a public listing.
What is the sensing distance and output type?
Rated operating distance is 2 mm, flush mountable. Output is PNP normally open, switching at 3000 Hz, 200 mA maximum continuous current.
What ingress protection does the SIEN-M12B-PS-S-L carry?
IP65 and IP67, meaning the brass housing and PBTP face withstand washdown and temporary immersion — suitable for wet or dusty machine zones.
