LRD8200 Ultrasonic clear label sensor for all labels. Pushbutton and Gap Quickset adjustments. The LRD8200 clear label sensor is designed to make your label-sensing life as easy as possible. Easy pushbuttons and Gap Quickset mean quick and easy adjustment to label stock - one click and you're set with "Gap Quickset." No need for complex button sequences, reading tiny displays, or interpreting flashing light codes to determine what you've just changed or adjusted. Avoid costly "eye-marks" on label webs which are required for optical sensors. Clear label sensors pay for themselves quickly when you stop ordering eye-marks on your labels.


Ultrasonic sensing works much like single-ended capacitive sensing except instead of an electric field, it uses high-frequency sound energy. A transmitting transducer ("speaker") in the base of the sensor transmits sound to a receiving transducer ("microphone") in the top of the sensor. The label web reduces the amount of sound reaching the receiver. The thicker the web, the less sound at the receiver. The sensor electronics measure the sound pressure at the receiver and triggers the control when a label edge is detected. This technology has no sensitivity to metallic materials. This is the newest type of clear label sensor., but not necessarily the best.
