Photo sensors

Photojournalism

Photoelectric sensors work on the principle of detecting changes in light intensity. These sensors respond to changes in light, allowing the presence, absence, position and movement of an object to be accurately detected. They are widely used in object counting and positioning.
We offer photoelectric sensors from Datasensing (Datalogic) and Idec, leading innovators and quality leaders in sensor manufacturing.

Don't forget accessories

We offer a wide range of different clamps for mounting cylindrical and square photoelectric sensors.
Several types of sensors also require a reflector (mirror). The SA1U photoelectric sensor kit already includes an L-clamp and a reflector if required.

Types of photo sensors

Technology	Drawing	Description
Detection of interruption of a through-beam Through-beam		The sensor is triggered when the beam between the two transceivers is interrupted. Also available with Class 1 laser beam. Transmitter and receiver are two separate devices.
Polarized Reflected Fast Interrupt Detection Polarlized Retroflective		The sensor is triggered when the reflected beam from the reflector is interrupted. The transmitter and receiver are in the same housing.The SA1U sensor has a reflector as a kit.
Detection of reflection from an object (diffuse reflection) Diffuse-reflective		The sensor is triggered when the receiver detects a fast reflection of the transmitter from an object. Transmitter and receiver are in the same housing.
Detection of reflection from a short distance object Small-beam Reflective		The sensor is triggered when the receiver detects a fast reflection of the transmitter from an object. The distance to the object is very small. The transmitter and receiver are in the same housing.
Detection of reflection from an object by background suppression Background Suppression		The sensor is triggered when the receiver detects a fast reflection from the transmitter from an object. Background noise attenuation is added (when the object and the background have similar reflections). Transmitter and receiver are in the same enclosure.
Detection of reflection from an object at a fixed distance Convergent Reflective		The sensor is triggered when the receiver detects a fast reflection of the transmitter from an object. The distance to the object is within a specified range. Transmitter and receiver are in the same enclosure.
Detection of transparent and highly reflective objects Coaxial Polarized Retro-reflective		The sensor is activated when the reflected beam from the reflector is distorted. Designed for transparent and highly reflective objects. Transmitter and receiver in the same housing.
