Types of Omron Photoelectric Sensors

Omron Photoelectric Sensors are designed with multiple sensing technologies and industrial-grade configurations to meet different automation requirements. Based on sensing method and application, Omron offers the following types of photoelectric sensors.

Omron Diffuse Reflective Photoelectric Sensors

Omron diffuse reflective sensors detect objects by receiving light reflected directly from the target surface. These sensors are widely used in packaging machines, conveyors, and assembly lines where short-distance detection is required.

Omron Retro Reflective Photoelectric Sensors

Omron retro reflective sensors use a reflector to detect objects when the light beam is interrupted. These sensors are suitable for medium-distance detection and are commonly used in material handling and industrial automation systems.

Omron Through Beam Photoelectric Sensors

Omron through beam sensors use separate emitter and receiver units placed opposite each other. When an object blocks the light beam, detection occurs. These sensors provide long sensing distance and high reliability in industrial environments.

Omron Laser Photoelectric Sensors

Omron laser sensors provide highly focused light for precise object detection and positioning. These sensors are used in high-speed and precision industrial applications where accuracy is critical.
