SICK Threaded Barrel Ultrasonic Proximity Sensor UM Series M18 1 m Detection 4 to 20 mA 30V UM18-218126111

SICK UM18-218126111 Threaded Barrel Ultrasonic Proximity Sensor from the UM series offers precise object detection within a 1 meter range using ultrasonic sensing technology. This M18-sized sensor features a metallic cylindrical housing measuring 52.7 mm in length and 18 mm in diameter for rugged industrial use. It provides an analogue 4 to 20 mA output signal compatible with most automation systems.

Designed to operate reliably in extreme environments, the sensor supports temperatures between -25°C and +70°C and carries IP65 and IP67 ingress protection ratings, preventing dust and water damage. The sensor incorporates reverse polarity and short circuit protections to enhance operational safety and longevity.

The 80 ms response time enables rapid measurement updates essential for dynamic industrial processes. The device uses an M12 connector for secure electrical connections and requires a DC voltage supply up to 30 V for optimal performance.

This sensor is well-suited for industrial applications such as tank level monitoring, precise distance measurement in harsh conditions, robotic spatial detection, logistics automation, and material handling systems. Its ability to synchronize up to 20 units without crosstalk broadens its use in complex sensor networks.

Compact threaded barrel metal housing with M18 thread size ensures robust installation. Operational temperature range from -25°C to 70°C supports harsh industrial environments. IP65 and IP67 rated protection enables dust and water ingress resistance.

Analogue interface with M12 terminal type facilitates standard industrial connectivity. Response time of 80 ms allows quick and precise measurement updates. Operating voltage up to 30 V DC ensures compatibility with common power supplies.

Reverse polarity and short circuit overload protection increase sensor reliability. Ideal for level measurement, distance sensing, robotics, logistics, and material handling.
