Ultrasonic sensor with switch output UDT18I

The device is an ultrasonic sensor for detecting the position of an object within the operating range. The sensor has an optically isolated transistor output with a PNP or NPN connection, with overload protection and back-up protection. The output NO / NC function is determined by the connection of the power terminals. Two limit positions (from the operating range) and the output mode can be set by a button on the housing.
