Schneider Electric SM552A100LE Ultrasonic Proximity Sensor

Schneider Electric SM552A100LE Ultrasonic Proximity Sensor is a flat-profile ultrasonic proximity sensor designed for non-contact detection of nearby objects in industrial automation. The SM552A100LE is part of Schneider Electric's SM55x family (commonly associated with the Telemecanique/Superprox line) and uses a compact flat profile to fit in tight spaces on conveyors, machine cells, and other automation equipment. Ultrasonic sensing works by emitting high-frequency sound and listening for echoes, enabling presence detection that is largely independent of object color, transparency, or surface texture and is less affected by dust, mist, or ambient light than some optical sensors. This makes the SM552A100LE suitable for harsh or dirty environments where traditional optical sensors might struggle. For exact electrical specifications, sensing range, outputs, compatibility with control systems, and mounting options, consult the official Schneider Electric datasheet for SM552A100LE and verified distributor listings, which provide the definitive, model-specific information for this sensor.
