THE WORLDWIDE LIMIT SWITCH STANDARD FOR INDUSTRIAL APPLICATIONS
For over 45 years, Telemecanique Sensors has been setting industry standards in photoelectric proximity sensors with innovative design solutions like the XUY roller conveyor sensor.
Telemecanique Sensors XU range offers a full line of photoelectric proximity sensors dedicated to material handling, packaging, labeling, assembly, lift & escalators or food & beverage industries.
This range offers many functionalities such as Diffuse mode, Background Suppression (BGS), polarized reflex, laser reflex & through-beam or through-beam, available in the 4 most popular formats worldwide.
The XU range is divided into 4 sub ranges for general purpose, lasers, forks and frames, and specific applications' sensors.
A photoelectric sensor basically comprises a light beam transmitter (light-emitting diode) and a light-sensitive receiver (photo-transistor). A light-emitting diode is an electronic semi-conductor component that emits light when an electric current flows through it. This light can be visible or invisible, depending on the transmission wavelength.
Detection occurs when an object enters the transmitted light beam and, in so doing, affects the intensity of the light at the receiver. As the light intensity at the receiver decreases, a point is reached whereby the output of the sensor changes state.
Depending on the model and application requirements, the transmission beam is either non-visible infrared (which is most common) or ultraviolet (for detection of luminescent materials). It may also be a visible red or green (for color mark reading etc.) and laser red (for long sensing distance and short focal length).
The advantage of LEDs is their very fast response. To render the system insensitive to ambient light, the current flowing through the LED is modulated to produce a pulsed light transmission. Only the pulsed signal will be used by the photo-transistor and processed to control the load.
Listed below are different variations of the XU range, each accompanied by a description to help you choose the perfect photoelectric solution.
Through-beam system or multimode set in through-beam mode
Polarised reflex system or multimode with reflector accessory

Constructed from metal, the optical fork is a robust sensor that is particularly suited to
conveying and packaging applications and detection of labels.
The fiber acts as a light conductor. Light rays entering the fiber at a certain angle are conveyed to the required location, with minimum loss.
All our sensors are available either in pre-cabled version (except XUX; screw terminal with cable gland version) or connector version.
The connectors used are M12 (4-pin), M8 (4-pin) or 1/2" 20UNF (3-pin).
Through-beam systems. Polarized reflex systems. Diffuse systems. With background suppression. Without background suppression. Optical forks. Fiber optics.
