1. GENERAL DESCRIPTION In the photocell AFT25B the transmitter can be powered with two 3.6V 2.7Ah Lithium-Tionyle Chloride batteries or with an external power supply at 12-24 VACDC, selectable with a jumper. The photocell has two terminals in which the output contact of a safety device (e.g. a rubber edge) can be connected, and it is particularly suitable to be used in sliding gates, mounted on the moving wing, allowing to connect the edge safety device without long cables or self-winding cables. Battery life is more than 15 months. The photocell is manufactured in compliance with the European directive 98/336/EEC (EMC).
2. APPLICATIONS In sliding gates or other kinds of installations where cables cannot be used or must be reduced (e.g. in existing installations where a safety device must be added)
