Photoelectric Sensors
Optical sensors utilize light in different ways to carry out detection tasks, offering a wide range of reliable and efficient solutions for applications that can be addressed optically. Depending on the object's surface, size, or color, different sensing principles are required. These include through-beam sensors, retroreflective sensors, and diffuse reflection sensors. Often, multiple operating principles are available within the same product series, providing flexibility for various needs. Additionally, universal sensor series are available with extended models that incorporate useful features to enhance performance in more complex detection scenarios.

Through Beam Sensors- Through-beam sensors have a separate light source (emitter) and receiver placed on opposite sides of the detection area.
- Objects are detected when they interrupt the light beam between the emitter and receiver.
- These sensors offer high accuracy and long-range detection, ideal for applications requiring precise object detection.
-
![]()
Retroreflective Sensors- Retroreflective sensors use a light source and receiver on the same side, with a reflector opposite to bounce the light back.
- Objects are detected when they block or disrupt the reflected light beam.
- Ideal for long-range detection and simple installation in applications with opaque objects.
-
![]()
Proximity Sensors- Proximity sensors integrate both the light source and receiver in one housing, typically using infrared or visible light.
- The light source emits a lens-shaped beam that travels toward the target. The receiver captures the reflected light, detecting the object's proximity based on the amount of reflected light.
- These sensors are effective for reliable detection in varied conditions and can be fine-tuned for detecting objects at varying distances, depending on object size and reflectivity.

Multimode mode, Din rail mount- Multimode sensors combine multiple sensing methods, such as through-beam, retroreflective, and proximity modes, into one device for greater versatility.
- These sensors can switch between modes depending on the application's needs, offering flexibility for various detection tasks.
- Multimode sensors are ideal for complex environments where different sensing methods are required to handle a range of object types, sizes, and materials.
