PH00: pair of synchronised traditional photocells (without ECSBus System). Only for GD0N.
Maximum security: electronics protected by a second plastic enclosure to prevent damage during installation. The antidazzle circuit protects you from blinding glares generated by the sun or other powerful light sources.
Convenience: very simple alignment thanks to the LED signal with proportional flashing.
Sturdiness: extra thick polycarbonate body.
