Proximity Sensors

1. Overview

Proximity sensors are non-contact detection devices that identify the presence, absence, or distance of objects within a specific range. These sensors convert physical phenomena into electrical signals, enabling automated systems to perceive environmental changes. Their importance in modern technology spans across industrial automation, consumer electronics, automotive safety systems, and smart infrastructure, providing critical data for process optimization and human-machine interaction.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Inductive Proximity Sensors	React to metallic objects via electromagnetic fields	Industrial machinery position detection
Capacitive Proximity Sensors	Respond to dielectric properties of materials	Level detection in chemical tanks
Photoelectric Sensors	Use light beam interruption/reflection principles	Automatic door systems
Ultrasonic Sensors	Measure distance via sound wave propagation	Vehicle parking assistance
Hall Effect Sensors	Respond to magnetic field variations	Brushless motor commutation

3. Structure and Components
