SICK IM12-04BPS-ZW1 Inductive Proximity Sensor

The SICK IM12-04BPS-ZW1 is a compact inductive proximity sensor from the IM Standard family designed for metal-target sensing in tight spaces. It operates from a 10–30 V DC supply and provides a 3-wire PNP SPST-NO output through an M12 x 1 connector, making it easy to wire into common PLC circuits. With a 4 mm sensing distance, it detects metal targets without contact, enabling reliable presence or position sensing on small parts, at end-of-travel stops, or along conveyors in automation cells. The IM12-04BPS-ZW1 configuration belongs to SICK's miniature, rugged proximity switches, featuring a metal housing built for industrial environments and repeatable switching across typical cycle rates. This variant is well suited for applications where a compact form factor, straightforward DC wiring, and a single switching output are desired for integration with PLCs, relays, or sensor interfaces in manufacturing, packaging, and material handling lines.
