Adjustable Wall Photocells

XP 20 D

System with traditional 24V transmitter and receiver power supply.

XP 20B D

System with BUS 2easy power supply, just two 24V non-polarized wires, possibility of installing up to 16 pairs of photocells on the same system and protection from interference produced by external light sources (such as vehicle LED headlights).

XP 20W D

System with traditional 12/24V receiver power supply and traditional or batteryoperated transmitter power supply. It avoids having to lay a cable to the transmitter (battery) and features selectable channels which allows the installation of up to 4 pairs of photocells and protection from interference produced by external light sources (such as vehicle LED headlights).

XP 20 D Adjustable Wall Photocells

Transmitter and receiver with modulated infrared beams

The new XP 20 D adjustable photocells comprise a transmitter and a modulated infra-red receiver with a range of up to 20 m. The obstruction of the light beam causes the receiver status to change.

Accurate and reliable adjustment

The photocell is housed in a swivel support fitted with a high-performance lens designed to optimise the efficiency of the beam in any direction. The swivel support is locked in the desired position thanks to a hard-wearing quick-fit swivel lock (which can be removed with a screwdriver where necessary).
