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

The SICK ultrasonic sensors(UM18/UC30/UC4) show their strengths in the contact-free detection of objects in all imaginable applications. The ultrasonic sensors perform measurement and detection tasks in a wide variety of application areas on colored, shiny, or transparent surfaces, which are particularly challenging for optical sensors. Even adverse ambient conditions such as dust, dirt, or fog hardly affect the measurement result. The broad detection range also allows for a large field to be monitored with just one sensor – with a measuring range of 13 mm to 8 m.
