Infrared Photocell with catadrioptics Barrier of 5 mts.

The K-840 Photocell works for reflection, to a maximum distance of 5 meters. Used as reflective a catadrioptic mirror of 80 m / m in diameter and REF MR-6 (Other measures on request). Photocell is supplied with each reflector. Built into the same photo-cell, is the amplifier, the output relay and Optics.

The standard voltages are: 220-110-24 and 12 V. a.c. and d.c. Has no external adjustment knob, so its use is very simple. A red pilot lights to be focused on the reflector, shutting down if its detects an object. The fastening is done with the help of the squad Ref. 74800, two-way directional and that can be placed on both sides of the photocell.

The photocell is supplied without buzzer.
