Baumer UNDK 30P3703 S14 Proximity Sensor

The Baumer UNDK 30P3703/S14 ultrasonic proximity sensor provides reliable object detection and distance measurement across a 100–1000 mm sensing range. It features a PNP output with short‑circuit and reverse polarity protection, a green output‑state indicator LED, and a flashing target indicator to confirm detection. Built with a metallic housing and an IP67 rating, the sensor is designed for harsh industrial environments and uses an M12 x 1 connector with a four‑conductor cable ( brown, black, blue, white) for straightforward PLC or controller integration. Operating temperature spans from −10°C to 60°C, and the unit offers fast response times (ton under 50 ms) to support tight control loops. Typical applications include object detection, level and distance measurement, and motion sensing in automation systems where precise, non-contact sensing is required.
