K4200 Series
Stem and Swivel Mounting
The K4200 Series Photo Controls feature stem and swivel mounting,
with thermal-type controls. Thermal-type photo controls, 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 sulde 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.
