Baumer sensors are devices that:
👉 Detect physical changes (position, distance, speed, pressure, etc.)
👉 Convert them into electrical signals for control systems (PLC, CNC, etc.)
⚙️ Main Types of Baumer Sensors
1. 🔵 Inductive Sensors
Detect metal objects only
Work using electromagnetic field
✅ Features:
Very robust
Resistant to dust, oil, vibration
🏭 Applications:
CNC machines
Metal detection
Position sensing
2. 🔴 Photoelectric Sensors
Use light (infrared/laser) to detect objects
Types:
Through-beam
Retro-reflective
Diffuse
✅ Features:
Detect almost any material (plastic, glass, wood)
3. 🟢 Capacitive Sensors
Detect metal + non-metal
Sensitive to:
Liquid
Powder
Plastic
4. 🟡 Ultrasonic Sensors
Use sound waves
