Baumer Group UNAM 18P6903 S14 Ultrasonic Sensor

Baumer UNAM 18P6903/S14 ultrasonic proximity sensor detects targets non‑contact from 100 to 1,000 mm, using a 240 kHz ultrasonic frequency for reliable performance in industrial environments. It provides a PNP normally‑open output for direct load switching and operates on a 12–30 V DC supply, up to 200 mA. The compact M18 cylindrical housing is brass with nickel plating and uses a 4‑pin M12 connector, with an IP67 rating that protects against dust and water ingress and supports use on rugged factory floors. The sensor supports teach‑in adjustment and includes a visual aid in the form of target indication flashing and a status LED to indicate sensing status at a glance. With an operating temperature range of -10 to +60 °C, this Baumer sensor is well suited for applications such as presence/absence detection on production lines and proximity sensing tasks within the 0.1–1 m window in harsh environments where non‑contact measurement is essential.
