Function
The UM18-2 Pro is an ultrasonic sensor for performing non-contact
distance measurement or detection of objects, animals, and persons.
The circuit variations have the following operation modes: Distance to
Object (DtO), Window (Wnd), and Object between Sensor and Background
(ObSB). The measured distance value is transferred cyclically over an
IO-Link interface.
Depending on the model, the analog versions output a voltage or current
value corresponding to the measured distance value and the scaling on
the customer side.
