L2100 - Description
L2100 is used to detect the position of the rotating unit.
L2100 has two optical switches that generate sensor
signals ROTSW1 and ROTSW2 according to which
position is activated.
L2100 includes a transmitter LED, and a receiver, or
base. The sensor signals remain on as long as the base
receives light from the LED. When the light to the base
is cut off by the positioning rail, the sensor signal is
switched off.
