Clear Object Ultrasonic Sensors

Bulletin 873E RightSound™ Clear Object Ultrasonic Sensors are opposed-mode sensors consisting of an emitter and a receiver. The receiver is microprocessor-based and provides advanced temperature stability and noise immunity. The emitter volume control adjusts the volume for the sensing distance and other variables of your application.
