The K4000 series fixed position mounting photo controls are thermal type photo controls that fit into a standard outlet box, post lamp, or wall pack. The photo controls provide dusk to dawn lighting control along with a delay action, which eliminates loads switching off due to car headlights and lightning. The thermal type controls feature a cadmium sulfide photocell and a sonic welded polycarbonate case and lens to seal out moisture. The design utilizes a dual temperature compensating bimetal and composite resistor for reliable long life operation over ambient temperature extremes.
