PHOTOCELLS

These devices are photoelectric cells that act as daylight control sensors, allowing the equipment switching to day or night status.
MSM photocells are one more complement to the proper operation of our beacons. They are also compatible with a good number of other beacons in the market.
Thanks to its encapsulation, they are highly resistant to the harshest marine conditions of humidity and salinity.
