The Festo SIEN-6,5B-PS-K-L is an inductive proximity sensor with a 6.5 mm diameter barrel, sensing range of 1.5 mm, and a PNP normally open switching output. It operates on 10-30 V DC and can sink up to 200 mA. The cable connection makes it a direct-fit replacement for existing M6.5 sensor ports in pneumatic actuators or compact machine frames.

Frequently asked questions
What is the closest functional second-source to the SIEN-6,5B-PS-K-L?
The SIEH-M12B-PS-K-L is a peer with the same PNP NO output, 10-30 V DC supply, and 200 mA rating, but uses an M12 barrel and offers a 4 mm sensing range. It will not drop into the same mounting hole without an adapter.
What is the listed type and model of this component?
The type is Inductive Proximity Sensor and the model is SIEN-6,5B-PS-K-L.
Will the SIEN-6,5B-PS-K-L drop into a panel specified around the SIEH-M12B-PS-K-L without rewiring?
Electrically yes — both are PNP NO, 10-30 V DC, 200 mA. Mechanically no — the 6.5 mm barrel is smaller than the M12 hole, so a bushing or adapter is required.
