Industrial M851040 USNT Inductive Proximity Sensor

PERLOS M851040 USNT is an industrial inductive proximity sensor designed for non-contact detection of metal targets in automation environments. Inductive proximity sensing detects metal objects through magnetic field interaction, allowing reliable metal presence and position sensing without any physical contact and minimizing wear on moving parts. The M851040 USNT model from PERLOS is intended for use in manufacturing and automated equipment where fast, repeatable switching is required when a metal target enters or leaves the sensing field. In typical automation tasks, this sensor supports metal-part detection on conveyors, position reference on actuators, and presence verification for metallic components during assembly. By sensing metal targets without contact, it helps simplify control logic and reduce maintenance costs associated with mechanical switches. Its inductive sensing principle provides repeatable performance across a range of industrial layouts and is applicable to applications where metal targets are common in the workflow, such as inline metrology, part orientation checks, and automated feeding processes. The M851040 USNT designation identifies this unit within PERLOS' lineup of metal-detection sensors.
