Industrial PS-510 Inductive Proximity Sensor

The Aleph PS-510-105 is a compact reed-switch proximity sensor intended for general-purpose position sensing in industrial equipment. It provides a normally closed (NC) output and is actuated by an external magnet; when the magnetic target is present, the reed contacts close to complete the circuit. Designed for DC operation at 100 V and rated to switch up to 0.5 A, it sits in a rugged, sealed package described as drip-proof and dust-proof for basic environmental protection. Part of Aleph’s PS-510 family, this sensor belongs to a line of miniature, magnetically actuated proximity sensors that rely on a reed switch rather than an inductive coil. Typical applications include door or lid detection, home or limit-position sensing, and other simple proximity tasks in automation systems where a compact, low-cost switch is desirable. The PS-510-105’s general-purpose, magnet-activated design makes it compatible with straightforward wiring schemes and replacement in legacy equipment that uses reed-type sensing.
