Photo Detectors

This NSi Industries 5021M photocontrol accepts 105-130 VAC input, has a 1,800 VA ballast capability, and can power a 2,000 watt lamp for applications such as street and highway lighting. The 1/2" cadmium sulphide photocell turns on lighting when the ambient light level drops below one to three foot candles (fc) and works with screw-base compact fluorescent (CFL) and LED bulbs. The photocell turns lighting off when the level exceeds three foot candles. The metal oxide varistor (MOV)-type surge arrestor reduces electric noise interference. The polypropylene photocell housing is UV stabilized and the clear acrylic window is UV-resistant. This photocontrol unit meets EEI NEMA standards for locking-type photocontrols, is Underwriter Laboratories (UL) Listed and Canadian Standards Association (CSA) certified, and is suitable for controlling lighting.

Automatic switches are used to turn on or off electrical devices and are activated by time, light, and motion. Time activated switches (also known as timers) operate at preset time intervals during a daily or weekly period and can be either mechanical or electronic. Mechanical timers feature a dial with multiple pins to set the on/off time intervals. Electronic timers feature an LCD display and pushbuttons to set the time intervals. Light activated switches (also known as optical or photo) operate when ambient light levels reach preset values, generally measured in foot candles. Motion-activated switches (also known as motion sensors) operate when an electronic field of a preset range is interrupted. These switches can include energy saving logic that uses combinations of time, light, and motion to operate and can include one or more device outlets or circuit contacts. Automatic switches are used to control indoor lights, outdoor lights, appliances, and small equipment motors.
