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.

Terminology
● Light Resistance :
Measured at 10 lux with standard light A
Sensitive surface
Electrodes
(2854K-color temperature) and 2hr.
Ceramic substrate
preillumination at 400-600 lux prior testing.
● Dark Resistance :
Resin Encapsulation
Conducting resin
Measured at 10th seconds after closing 10 lux.
● Gamma characteristic :
Lead wires
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.
● Pmax :
100 CdS
Max. power dissipation at ambient
temperature of 25°C.At higher ambient
temperature,the maximum power permissible
may be lowered.
80
60

CdSe
Cd(S.Se)
● Vmax :
20
Max. voltage in darkness that may be
applied to the device continuously.
0
400 500 600 700 800 900 1000
● Spectral peak :
Wavelength(nm)
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.
