Description of Sensor Function
An ultrasonic thru-beam sensor always consists of an ultrasonic emitter and receiver. The working principle of the ultrasonic thru-beam sensor
is based on the interruption of the transmission from the emitter to the receiver by the object to be detected (obstacle).
The emitter produces an ultrasonic signal which is evaluated by the receiver. If the signal is damped or broken by the object being detected,
the receiver switches state.
No electrical connections are required between the emitter and receiver.
Sensitivity adjustment
The sensitivity is adjusted using the input ET. This can be open or connected using +U
B
or -U
B
.
(1) The specified values for B and L are reference values and refer to the maximum distance D and to objects with a rectangular shape. The
shape of the objects can have an effect on the values for B and L.
Safety Note
The use of this device in applications, where the safety of persons depends from the devices function, is not allowed!
