M18 Photoelectric Sensor (Through Beam)
M18 Photoelectric Sensor (Through Beam)
Overview
The M18 Photoelectric Sensor (Through Beam) is a high-performance sensor widely used in automation and industrial control fields. By detecting the presence or absence of objects through the light beam between the emitter and receiver, it offers high precision and reliability, providing stable detection performance in various complex environments.
Working Principle
The through-beam photoelectric sensor consists of two separate parts: the emitter and the receiver. The emitter emits a beam of light (usually infrared or laser), which directly reaches the receiver in the absence of obstacles. When an object blocks the light beam, the receiver does not detect the light, thus outputting a signal indicating the presence of an object.
Key Features
- High Sensitivity: Through-beam sensors have extremely high sensitivity, capable of accurately detecting small objects and fast-moving targets.
- Long Detection Range: Compared to reflective and diffuse sensors, through-beam sensors have a longer detection range, often reaching several meters or even tens of meters.
- Strong Anti-Interference Ability: Since the emitter and receiver operate independently with a clear light path, they have strong resistance to ambient light interference, making them suitable for various complex industrial environments.
- High Reliability: The robust housing design and high-quality optical components ensure high reliability and long lifespan even in harsh environments.
Application Areas
- Manufacturing: Used for detecting the presence, counting, and positioning of products on assembly lines.
- Packaging: Used for detecting the presence, size, and shape of packaging materials.
- Warehouse Logistics: Used in automated warehouse systems to detect the position and movement of goods.
- Traffic Control: Used in vehicle detection and gate control applications.
- Robotics: Used in industrial robots for object recognition and position detection.
