This compact ultrasonic sensor with IO-Link technology can be taught as a standard sensor via teach-by-wire or programmed and used via IO-Link. Advanced functions such as synchronization allow multiple sensors to be synchronized without the risk of interfering with each other. When used in this mode, all sensors will transmit and receive information together, which increases the coverage area and provides a single output from multiple sensors. Multiplexing mode allows several sensors to be mounted close together without interference while providing individual outputs. These sensors are offered in front and side sensing models, rated to IP67.
