Photocells are wall-mounted (LINEAR) or flush-mounted (105/N) external safety accessories that help to make automations even more reliable.
The devices are always sold in pairs and cover a maximum distance of 20m.
If necessary, the operation of photocells powered with alternating voltage can be synchronized to prevent transmitters and receivers of different pairs from interfering with each other.
Some models in the DEA photocell range are equipped with adjustable optics, a useful element when photocells are not perfectly aligned.
