Light-sensitive components whose resistance changes (decreases) with the amount of light falling on their surface are called photoresistors (LDR - light dependent resistor). These are the simplest and cheapest components that can work as light detectors. For many years, they have been used in various types of fire detectors, smoke detectors, readers, and recently they have become popular elements in lighting control systems (e.g. street lamps).
PGM 12 series photoresistors manufactured by TOKEN, supplied as ⌀12mm sensors enclosed in hermetic packages (MP series) or packages encapsulated with epoxy resin. They are fitted with soldering lead wires.
These photoresistors are characterized by a short response time and high “dark” resistance.
