Sick UC4 Series Ultrasonic Rectangular-Style Ultrasonic Sensor, 13 → 150 mm Detection, NPN, PNP Output, 15

The UC4 ultrasonic sensor family combines state-of-the-art ultrasonic technology in a miniature housing. With reliable functionality in even difficult operating conditions, the UC4 is a real miniature all-rounder when it comes to demanding, specialized tasks such as detecting transparent objects or measuring the levels of fluids and bulk materials. Even in situations with high requirements for background suppression or contamination tolerance, the UC4 with switching, analog, or push-pull output with IO-Link has proven itself as the ideal choice. And to top it all off, the portfolio even includes variants with increased switching frequency for extremely fast applications.

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.
