Photocell LS 55/3
• The photocell LS55/3 is a transmitter/receiver
photocell with 2-wire technology. It was designed
especially for the use in a combination with the
garage door operator GTZ.
• Special features of the photocell LS 55/3 are
the extraordinary small dimensions, the easy
and fast surface mounting and adjusting.
• The operation is carried out with modulated
infrared light. The receiver´s LED lights red
and the transmitter´s LED lights green. An
interruption in the light beam causes a shifting
of the electrical contact in the receiver and the
transmitter´s green LED goes out.
