Photoresistors (results: 29)

Photoreistors – A Symbol of Modern Electronics

A significant breakthrough in the global electronics industry was the discovery of the electrical properties of semiconductor materials. These are often crystalline products whose conductivity can be virtually altered by introducing various dopants, modifying temperature, or converting the intensity of light falling on the semiconductor.

Electronic components that utilize the photoelectric properties of semiconductors are known as photoreistors, also referred to as photoresistors. The primary role of photoreistors is to detect light intensity and convert this information into an electrical impulse.

Photoreistors - Key Parameters to Consider

• Spectral Sensitivity (the relationship between electrical resistance and light intensity).
• Dark Resistance "RD" (resistance in the absence of light).
• Resistance "Rxx" – the resistance of the device at a specific light intensity (e.g., R10, R50).
• Coefficient "n" - the ratio of dark resistance to resistance at a given light level (e.g., n=RD/R50).
• Maximum Operating Voltage.
• Maximum Power.
• Switching Time.
• Operating Temperature.

MICROS Photoreistors for Specific Applications

Thanks to their high sensitivity and simple measurement circuitry, our photoreistors are often used for temperature measurement through radiation intensity, making them suitable for heat detection systems or fire alarm systems.

They are also frequently used in systems dependent on specific times of day (e.g., automatic raising and lowering of window blinds or lighting control). The MICROS photoreistor shop offers solutions with power ratings of 100 mW, 250 mW, 500 mW and light resistances in ranges of 5-10 kΩ, 10-20 kΩ, 20-30 kΩ, 50-100 kΩ, and 100-200 kΩ.
