Advanced Photonix Light Dependent Resistor (LDR) TO-8 Two-Pin

The Advanced Photonix Light Dependent Resistor (LDR) is a passive two-pin sensor with a minimum dark resistance of 1 MΩ, whose resistance varies with the intensity of ambient light.

Overview

This light dependent resistor operates on a simple principle: its resistance is high in darkness and drops significantly when exposed to light. It is housed in a TO-8 metal can package and is suited to automation and control applications that require light sensing.

Key Features

• Minimum dark resistance of 1 MΩ, for minimal current flow in low-light conditions
• Typical resistance around 17 kΩ when illuminated, giving a clear signal change
• Maximum voltage rating of 320 V
• Power rating of 500 mW
• Two-pin configuration for integration into printed circuit boards (PCBs) or prototyping setups
• TO-8 metal can package

Specifications

• Operating temperature range: -60°C to +75°C
• Compact dimensions for space-constrained designs

Applications

This component can be used in simple light-activated switches and in more complex analogue light metering systems. Typical uses include automatic night lights, street light controllers, camera exposure meters, burglar alarm systems that trigger when a beam of light is broken, and solar-powered devices that detect daylight.

Choose the Advanced Photonix Light Dependent Resistor (LDR) when you need a two-pin light-sensing component for circuit designs ranging from simple switching to analogue light measurement.
