Ultrasonic sensors UM18

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

Features

  • Reliable measurement, regardless of material color, transparency, gloss, or ambient light.
  • Sensing ranges up to 1,300 mm.
  • Short metal or plastic M18 housing from 42 mm in length.
  • Straight or angled design.
  • Immune to dirt, dust, humidity, and fog.
  • Versatile interfaces including IO-Link available.
