The K4100 and K4400 Series Photo Controls feature stem mounting, thermal-type, controls with single and multi-voltage models. Thermal-type photo controls 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.

• Mechanical bimetal switch with Cadmium Sulfide photocell
• Delay feature prevents unwanted OFF switching
• Gray plastic housing
• 1⁄2 in.-14 NPSM threaded stem
• Washer gasket and locking nut included
• #18 AWG, 9 in. wire leads
• Perfect for use with parking lot lighting, landscape lighting, exterior lighting, pedestrian pathway lighting, street lighting

Automatically have your outdoor light(s) turn on when it gets dark is perfect for your Pole Lanterns, Lawn Lighting, Walkways applications. It works with CFLS to create energy savings. Cell is cadmium sulphide, conformed coated, 1/2 in. Dia with contacts normally closed (the unit fails in the on position).

• Flush mounting through 0.6875 in. hole in post lantern or lighting fixture, 3/8 in. NPT, stem 3/4 in. long gasket and nut supplied, control housing is weather-resistant molded Lexan with ultrasonically welded seams
• Sensor is conformed coated cadmium sulphide photocell resists effects of moisture and airborne contaminants, photocell responds to the light spectrum near to that of a human eye
• Easy to operate as delay is up to 2 minutes to prevent false switching due to light from passing vehicles, lightning, etc. turn on is 1 to 5fc, turn off is 3 to 15fc
• Energy savings as it works with screw base CFLs with power consumption averages less than 1-Watt
• 5-year limited warranty
• Lead wires consists of 3 color coded, minimum 9 in. wire leads, #16AWG, rated for 105 degree C
• Temperature range of -40 degree F to +140 degree F (-40 degree to +60 degree C)

This 2001 SPST 180-swivel mounting in Lexan Housing 208-277-Volt photo control is great for your Flood Lamp, Patio Lamp, Decorative Lighting. The sensor is conformal coated cadmium sulphide photocell resists effects of moisture and airborne contaminants so that Photocell responds to the light spectrum near to that of a human eye. Meets ANSI/UL773A.

• All Lexan enclosures are impact and vandal resistant, translucent Lexan dome prolongs cell life by further screening out ultraviolet rays, dome and base are ultrasonically welded for maximum strength
• Sensor: conformal coated cadmium sulphide photocell resists effects of moisture and airborne contaminants, photocell responds to the light spectrum near to that of a human eye
• Energy savings is this photo control works with screw base CFLs and averages under 1-Watt power consumption, the turn on is 1 to 5fc; turn off is 3 to 15fc, without the slide in position, ON/OFF adjustment is easily made by moving a slide cover, no tools required
• Photo control is easy to operate as delay is up to 2-minutes to prevent false switching due to light from passing vehicles, lightning, etc. with temperature range -40 degree to +140 degree F (-40 degree to +60 degree C)
• Photo control cell is made of cadmium sulphide, epoxy conformal coated, 1/2 in. Dia with contacts that will remain closed between dusk and dawn, (the unit fails in the on position) and 3 colors coded lead wires, minimum 6 in. wire leads, #16AWG, rated for 105 degree C
