Buy light dependent photo resistor - a compact low cost cadmium sulphide light dependant photo resistor housed in a small package.

Coated With epoxy, good reliability, high sensitivity, fast response, good spectrum characteristic. Consists of a resistor which is made of semiconductor material whose conductance changes with variations in luminance. Typical applications include camera automatic photometry, photoelectric control, lighting control, annunciators, industrial control, light control switches and lamp electronic toys.

  • 5mm diameter
  • Clear epoxy finish
  • Resistance reduces as the light falling on the device increases
  • Note: This product contains cadmium sulphide, the use of which is restricted by the RoHS directive

Q. Can you tell me the pitch of this please URGENT cheers kev
A. Hi Kevin, the pitch is 3mm.

11 March 2012 Question by: James | Product code: 58-0134
Q. Does this LDR have a minimum voltage? Thanks
A. Hi James, thanks for your question. There is no minimum voltage - an LDR is just a resistance that changes with light.

I use hundreds of these LDRs and not one failure in three years.
