This cadmium sulfide (CdS) or light dependent resistor (LDR) whose resistance is inversely dependent on the amount of light falling on it is known by many names including the photo resistor, photoresistor, photoconductor, photoconductive cell, or simply the photocell.

This cadmium sulfide (CdS) or light dependent resistor (LDR) whose resistance is inversely dependent on the amount of light falling on it is known by many names including the photo resistor, photoresistor, photoconductor, photoconductive cell, or simply the photocell.

A typical structure for a photoresistor uses an active semiconductor layer that is deposited on an insulating substrate. The semiconductor is normally lightly doped to enable it to have the required level of conductivity. Contacts are then placed either side of the exposed area. The photo-resistor, CdS, or LDR finds many uses as a low cost photo sensitive element and was used for many years in photographic light meters as well as in other applications such as smoke, flame and burglar detectors, card readers and lighting controls for street lamps.

TORK a brand of NSi Industries, LLC Lexan Housing with Weatherproof Sealant Photocontrol, 2080-2770VA Ballast, SPST Switch, 3470-4620W Power, 208-277VAC Voltage - 2000-2

Model: 2000-2   |    Mpn: 2000-2   |    Ean: 0786261600189   |    PartNumber: 2000-2   |   Asin: B00CUNDY7Q

This NSi Industries 2000-2 switch and photocontrol accepts 208-277 VAC input and each of its three circuits can activate a 2,770 ballast for lighting control. The integral photocell turns on lighting when the ambient light level drops below a user-selectable light level of 1 to 5 foot candles (fc) and turns the lighting off when the level is at 3 to 15 fc. The single-pole single-throw (SPST) contacts are housed within impact-resistant dome. The base is ultrasonically welded for maximum strength and the sensor accepts 1/2" conduit and has 180-degree swivel capacity. This switch and photo sensor unit is Underwriter Laboratories (UL) Listed and Canadian Standards Association (CSA) certified for quality assurance and is suitable for controlling lighting.

Specifications Switch type Photo sensor and switch, weatherproof Input power supply 120/277 VAC, 50/60 Hz, 1 watt power consumption Output contacts SPST contacts, 2,770 watt ballast capable, 4,620 watt load On/off control On at user-selectable 1 to 5 fc, Off at 3 to 15 fc Enclosure 1/2" conduit mount, indoor/outdoor use Terminal wire size range #16 AWG (American wire gauge) Operating temperature range -40 to +140 degrees F (-40 to +60 degrees C) Standards met UL Listed, CSA certified
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.

NSi Industries manufactures electrical components and sensors, lighting products, and energy management products. The company, founded in 1975, is headquartered in Huntersville, NC.

Features

  • Photocontrol for switching lights on/off based on ambient light

15pcs Photoresistor Photoconductive Cell Light Dependent Resistor 5-10K LDR 12mm Plastic package

 PartNumber: SG12516-P   |   Asin: B01J51QNV4


15pcs Photoresistor Photoconductive Cell Light Dependent Resistor 5-10K LDR 12mm Plastic package
CdS photoconductive cells utilize photoconductive effects in semiconductors that decrease their resistance when illuminated by light. These sensors are non-polar resistive elements with spectral response characteristics close to the human eye (luminous efficiency), thus making their operating circuits simple and small. Features Coated with epoxy Small volume Quick response Good reliability High sensitivity Good spectrum characteristic Applications Camera automation photometry Indoor sunlight control Industrial control Optical control lamp Optical control musicI.C Photoelectric control Annunciator Optical control switch Electronic toy Electronic proverbial vlitional Notes 1. To avoid the light-sensitive resistors on the humid, high temperature environment preservation. 2.In the use of the process, the welding time shortened as much as possible. 3.Note that lead soldering location should be 3 mm from the ceramic base (mm) or more.

Features

  • Allowable Power Dissipation ( PD ):200mW ( Derate above 25 1.0 mW/ )
  • Maximum Applied Voltage (at 25 ):250V DC or AC
  • Ambient Temperature Range ( TA ) : -40 +75
  • Light Resistance at 10Lux: 5-10K (2854k color temperature) and 2h pre-illuminaion at 400-600 lux prior to texting.)
  • Dark Resistance at 0Lux:.0.5/M ; Peak Spectral Response:540Nm

5000M Series Delayed Response Utility Grade MOV Surge Arrestor Photocontrol, 1800VA Ballast, 1/2" Light Sensor, 1000W Power, 105-130VAC Voltage, Grey

Model: 5021M   |    Mpn: 5021M   |    Ean: 0786261610157   |    PartNumber: 5021M   |   Asin: B00435HR4U

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.

Specifications Photocell type Cadmium sulphide photo sensor and switch, turn-lock mount, MOV surge arrestor Input power supply 105-130 VAC, 60 Hz Output 2,000 watts On/off control 1-3 fc ambient light, instant On, 3-5 seconds Off delay Enclosure Gray polypropylene, UV stabilized Mount style Turn-lock mount Operating temperature range -40 to +140 degrees F (-40 to +60 degrees C) Standards met UL Listed, CSA certified, ANSI C136.10, EEI NEMA
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.

NSi Industries manufactures electrical components and sensors, lighting products, and energy management products. The company, founded in 1975, is headquartered in Huntersville, NC.

Features

  • Cadmium sulphide photocell for on/off control
  • MOV-type surge arrestor for surge protection
  • Instant On cycle, delay of three to five seconds for Off cycle
  • 105-130 VAC input voltage, 1,800 VA ballast, 2,000 W output
  • Polypropylene housing, UV stabilized
