Photo sensors, also known as optical sensors, are among the most common types of position sensors. These sensors detect objects in front of them by measuring how the emitted beam of light reflects off an object’s surface. When the reflected light returns to the sensor, the presence of the object is confirmed. This is a popular solution, especially when the light emitter and receiver are combined into a single unit. However, other types of photo sensors are also available and can be adapted to various needs.

Main Configurations of Photo Sensors

Photo sensors can generally be categorized into three main configurations, depending on how the light beam interacts with the object:

Reflective with a Reflector: The light beam is directed at a reflector, which sends it back to the sensor. If the beam returns, no object is detected. If the beam does not return, it indicates the presence of an object. This type of photo sensor is easy to install and cost-effective, though often less precise.
Through-Beam Sensors: The most accurate option, where the light emitter and receiver are placed opposite each other, creating a continuous light beam. An object is detected when it interrupts this beam. These photo sensors ensure high accuracy and a long sensing range, but their installation is more complex.
Reflective from the Object: Similar to sensors that use a reflector, these rely on the object itself to reflect the light beam. The sensor registers the object’s presence when it receives the reflected light. For dark or black objects that absorb light, specialized high-performance sensors (such as Sick Power Prox) are available to detect even low-reflectivity targets.

Why Choose Photo Sensors?

Photo sensors have become widely used across manufacturing, logistics, automation, and other industries, because they offer:

High accuracy and reliability in object detection
Flexible adaptation to various environments and object types
Cost-effective solutions in terms of investment, installation, and maintenance

Regardless of the specific system requirements, photo sensors help optimize process flow, increase production efficiency, and ensure safe and stable operation across a broad range of applications.
