PNP NPN NO NC 24V M18 M12 Ultrasonic sensor

The double sheet ultrasonic sensor adopts the principle of through beam type sensor. Originally designed for the printing industry, the ultrasonic through beam sensor is used to detect the thickness of paper or sheet, and can be used in other applications where it is necessary to automatically distinguish between single and double sheets to protect equipment and avoid waste. They are housed in a compact housing with a large detection range. Unlike diffuse reflection models and reflector models, these doule sheet ultrasonic sensors do not continuously switch between transmit and receive modes, nor do they wait for the echo signal to arrive. As a result, its response time is much faster, resulting in a very high switching frequency.
