Product Overview

The Senbar LDR Sensor, also known as a Photoresistor, is a semiconductor device whose conductivity varies with light intensity. Constructed with epoxy resin for reliable encapsulation, these sensors offer high sensitivity, fast response times, and good spectral characteristics. They are widely used in various industries, including toys, lighting, and photography, for applications such as automatic light metering in cameras, photoelectric control, indoor light control, alarms, industrial control, light-controlled switches, and light-controlled lamps.

Technical Specifications

Test Conditions

• Maximum applied voltage: The maximum voltage that can be continuously applied to the component in darkness.
• Dark resistance: Resistance value measured 10 seconds after turning off the light to 10Lux.
• Maximum power: Maximum power dissipation at an ambient temperature of 25.
• Bright resistance: Test value under 10Lux light from a standard light source (color temperature 2856K) after 2 hours of illumination with 400-600Lux.
• Gamma () value: The logarithm of the ratio of standard resistance values at 10Lux and 100Lux illuminations. = Lg (R10/R100) / Lg (100/10) = Lg(R10/R100). R10 and R100 are the resistance values at 10Lux and 100Lux illuminations respectively (tolerance of is 0.1).

Packaging and Precautions

• This product uses environmentally friendly packaging materials. Small packages contain 100 pieces, and large packages contain 1000 pieces.
• Avoid storing photoresistors in humid or high-temperature environments.
• Soldering time should be as short as possible.
