Photoelectric sensors are used for reliable object detection using light-based technology in industrial automation systems.

• Diffuse Sensors – Detect objects directly; suitable for short-range applications
• Retro-Reflective Sensors – Use a reflector for longer sensing distance and stable detection
• Through-Beam Sensors – Separate transmitter and receiver for maximum reliability and long-range detection

Photoelectric Sensor Selection Guide

Choose the right sensor based on your application:

• Diffuse Sensors – Direct object detection for short-range applications
• Retro-Reflective Sensors – Longer sensing distance with stable detection
• Through-Beam Sensors – Highest reliability for long-range detection
• Frame / Fork Sensors – Precision detection for small parts and positioning
• Area Sensors / Light Curtains – Multi-point detection across wider areas
