This ultrasonic sensor delivers excellent beam control and strong signal transmittance. Therefore, it ensures stable and accurate detection. Moreover, the controller-integrated design simplifies installation and operation. In addition, the ultra-narrow ultrasonic beam angle of just 2.5 degrees per side enables precise targeting. As a result, users can install the sensor even in confined or complex spaces. Furthermore, the availability of both 4-wire and 2-wire DC power options increases system flexibility. Meanwhile, multi-controller configurations support up to 15 channel connections, so large-scale systems remain easy to manage. Consequently, this solution adapts smoothly to diverse industrial environments while maintaining reliable performance.
