光センサー GD-20N

1. Core Functions

It uses infrared/red LED light source, supporting multiple detection modes including diffuse, retro-reflective, and through-beam. Equipped with dual status indicator lights (power/output status), providing normally open (NO) and normally closed (NC) outputs. Features IP67 protection rating, ambient light anti-interference capability, and short-circuit protection, suitable for complex industrial environments.

2. Sensing Range (By Mode)

Through-beam: up to 20 meters

Reflective distance: up to 3.5 meters

Diffuse: 30 ~ 600mm (adjustable with background suppression models)

3. Response Speed

Standard models: response time < 1ms

High-speed models: up to 400μs, suitable for high-speed production lines and high-frequency detection applications.

4. Typical Applications

Object counting and presence detection on automated production lines

Transparent bottle/component detection in packaging, food, and electronics industries
