The K4400 series Photocontrols feature stem mounting, thermal type, controls with single and multi voltage models. Thermal type photocontrols provide dusk to dawn lighting control and a delay action, which eliminates loads switching off due to car headlights, and lighting. 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. These models are California title 24 compliant. M models are heavy duty die cast housings.
