Proximity sensor for industrial detection

The Festo SIEN-M12B-PO-K-L is a proximity sensor designed for automated position sensing in industrial environments. It provides a PNP normally open output signal when a metal target enters its detection field. The unit is sold as a single device in a box.

Suited for machine builders and maintenance teams

This sensor suits engineers integrating presence detection into pneumatic or conveyor systems where a 12 mm threaded housing fits. It is not for applications requiring analog distance measurement, non-metallic target detection, or a different thread size.

12 mm threaded housing defines fit

The M12 x 1 mounting thread is the critical dimension that determines whether the sensor installs in the prepared bore. Verify the thread pitch and clearance before ordering part number 150406.

Questions about this item

How can I confirm the SIEN-M12B-PO-K-L proximity sensor is working correctly after installation?

Apply a detectable target within the sensing range and verify the output signal changes state on your controller or multimeter; the red LED indicator on the sensor body should also illuminate when the output is active.

What is included in the box for the SIEN-M12B-PO-K-L and what must I purchase separately?

The box contains one SIEN-M12B-PO-K-L proximity sensor (part number 150406); mounting brackets, M12 connection cables, and a separate power supply are not included and must be sourced separately.

Which version of the SIEN-M12B-PO-K-L should I choose for my application?

The SIEN-M12B-PO-K-L is a single specific variant with PNP normally-open output and an M12 connector; choose this model only if your control system requires a PNP NO signal and you can wire an M12 plug.
