It comes with a 2.5 m cable and has a 12 mm diameter, 50 mm housing length.
The PNP output and normally open configuration are standard for many PLC digital inputs — this sensor pulls the input high when it detects metal. The 10-30 V DC operating voltage covers 24 V DC control systems common in industrial panels. The 2.5 m cable gives enough reach to a junction box or I/O module without a separate connector.
Inductive proximity sensors like this one detect the presence of metal targets without contact — used for end-of-travel sensing, part-present detection, or counting on conveyors and automated assembly lines. The M12 x 1 threaded barrel mounts through a bracket or directly into a tapped hole.
