Overview

The UM18 sensor product family provides simplicity and high functionality. The UM18 ultrasonic sensors are available in straight and angled versions for easy machine integration. A metal or plastic housing allows use in demanding ambient conditions. Due to four sensing ranges up to a total of 1,300 mm and LED status feedback, the sensors are suitable for a broad range of applications.

Whether analogue or PNP/NPN switching output, one or two push-pull switching outputs with IO-Link or the combination of analogue and push-pull switching output with IO-Link, sensors of the UM18 product family leave nothing to be desired.
