The K4021C Series Fixed Position Mounting Photo Control is a thermal-type photo control that fits into a standard outlet box, post lamp, or wall pack. The photo control provides dusk-to-dawn lighting control, along with a delay action, which eliminates loads switching OFF due to car headlights and lightning. The thermal-type control features 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.
