The TORK 3000 Flush Mounting Photocontrol with Lexan® Housing provides professional-grade performance for a range of residential and commercial applications. This photocontrol light sensor automatically detects nightfall, allowing you to run exterior lights from dusk to dawn. Use TORK flush mount photocontrols to automate ON/OFF switches for pole lanterns, lawn lighting and walkway applications. The TORK 3000 saves you energy and money, while adding security to your property at night with a time delay feature that prevents car headlights or other stray city lighting from accidentally turning the sensor OFF. A conformal coated cadmium sulphide photocell resists the effects of moisture and airborne contaminants and responds to the light spectrum near to that of a human eye. Additionally, a two-minute OFF delay prevents false switching from quick light changes due to headlights or lightning. This photocontrol is easy to mount through a .6875" hole in post lantern or lighting fixture using a 3/4" long, 3/8" NPT threaded stem with a mounting gasket and nut included. Rated for 120VAC. When choosing a photocontrol light sensor you can rely on, trust in TORK, a pioneer in the industry since 1922.
