BALLUFF Ultrasonic Block-Style Proximity Sensor, 20 → 250 mm Detection, PNP Output, 20 → 30 V dc, IP67

BUS Ultrasonic Proximity Rectangular Sensors. The ultrasonic proximity sensors from BALLUFF BUS range use ultrasonic technology to detect if an object moves within the sensing range. The sensor emits a high pitch ultrasonic beam of sound which reflects off the object in its path, when the object moves within the sensing range the sound will reflect back to the receiver unit triggering activation of the sensor. Ultrasonic proximity sensors are used in industrial environments for applications where accurate proximity detection of metal or non-mental objects is essential.
