The K4200 Series Photocontrols feature stem and swivel mounting, with thermal type controls. Thermal type photocontrols, which are available in single or multi voltage models, provide dusk to dawn lighting control and 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 bi metal and composite resistor for reliable long life operation over ambient temperature extremes. Volts: 208 277.
