K4221C

K4221C

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 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.

New Product Highlights

IOS-DDR-W

The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.

ICUBE

The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.


Surge Protective Device Group Shot

The Intermatic® Surge Protective Device with Consumable Modules covers 100% of a home’s big investment equipment, from appliances and computers, to HVAC equipment and TVs. The Surge Protective Device uses replaceable Consumable Modules that allows homeowners to easily and safely replace a module when the built-in LED light indicates it has been compromised.
