TOKEN PGM CDS Photoresistors CDS Light-Dependent Photoresistors Light-Dependent Photoresistors for Sensor Applications Preview The cadmium sulfide (CdS) or light dependent resistor (LDR) whose resistance is inversly 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. Providing design engineers with an economical CdS or LDR with high quality performance, Token Electronics now offers commercial grade PGM photoresistor. Designated the PGM Series, the photoresistors are available in 5mm, 12mm and 20mm sizes, the conformally epoxy or hermetical package offer high quality performance for applications that require quick response and good characteristic of spectrum. Token has been designing and manufacturing high performance light dependent resistors for decades. Our product offerings are extensive and our experience with custom photoresistor is equally extensive. Contact us with your specific needs.

Electrodes Ceramic substrate Resin Encapsulation ● Dark Resistance : Measured at 10th seconds after closing 10 lux. Conducting resin Lead wires ● Gamma characteristic : ● Pmax : Max. power dissipation at ambient temperature of 25°C.At higher ambient temperature,the maximum power permissible may be lowered. ● Vmax : Max. voltage in darkness that may be applied to the device continuously. Relative sensitivity(%) Under 10 lux and 100 lux and given by γ = log(R10/R100) / log(100/10) = log(R10/R100) R10, R100: resistance at 10 lux and 100 lux. The tolerance of γ is ±0.1. ● Spectral peak : CdS 100 80 CdSe 60 Cd(S.Se) 40 20 0 400 500 600 700 800 Wavelength(nm) 900 1000 Spectral sensitivity of photoresistors depends on the wavelength of light they are exposed to and in accordance with figure ‘Spectral Response’. The tolerance of spectral peak is ±50nm.
