A photoelectric sensor, or photoeye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter and a receiver. They are used extensively in industrial manufacturing. There are three different functional types: thru beam, retroreflective, and diffused.

Our
Pepperl + Fuchs UGB Sensors can reduce waste by identifying web splices and accurately detect manufacturer, automatic, and manual splices.

Pepperl + Fuchs has reintroduced their splice detector in a new, smaller package. Designed to sense splices in high-speed applications while ignoring differences in color.
The
Pepperl + Fuchs UGB splice detection sensor is insensitive to printing, colors, and glossy surfaces; simple, quick alignment and setup.
This series features two 18mm diameter sensing heads and is compact and easy to mount. Dual outputs indicate both splice and no sheet (air) conditions.

Fuchs introduces
VDM28 Laser Distance Measurement Sensor with Pulse Ranging Technology (PRT). These cost-effective laser sensors provide distance measurements from 200 mm up to 8 m with repeatable accuracy of <5 mm, with resolution of 1 mm and response time as fast as 10 ms, regardless of target surface. Pulse Ranging Technology is an advanced method of laser distance measurement sensors that provides more precise measurement than phase correlation and time-of-flight techniques.
At just 88 mm x 26 mm x 54 mm,
VDM28 Laser Distance Measurement Sensors are the industry’s most compact PRT-based sensors. They feature a visible red laser light source with a small, well-defined light spot for quick, accurate alignment.
Marshall Wolf Automation is your Pepperl & Fuchs distributor for
laser distance measurement sensors and also their
Visolux line of sensors.
Visolux sensors were acquired by Pepperl + Fuchs about 10 years ago!Marshall Wolf Automation is a large industrial automation distributor for the full line of Pepperl + Fuchs... including Visolux!
We can find you the exact replacement or suggest the closest sensor option. All we need is the Visolux sensor part number!

DK50-UV Luminescence Sensors from Pepper + Fuchs distinguish between conditions that may involve invisible or irregular objects. The DK50-UV emits ultraviolet (UV) light, which is invisible to the human eye. Some materials, either inherently or intentionally, contain luminophores that are stimulated by the UV light and emit visible light at a certain wavelength. The DK50-UV detects the target when this visible light is received.
TYPICAL Applications:
Measure amount of glue or adhesive
Verify presence of oil or lubricant
Test for leaks in seams
Verify presence of packing slip in carton
Sense invisible markings on packaging or printing media
Confirm presence of clear protective coatings
Detect straw pouch on juice box
Confirm presence of gaskets
Marshall Wolf Automation is one of the largest

The Pepperl & Fuchs RLG28 retroreflective area sensors are great for a number of
applications including:
- Leading edge detection of pallets
- Identification of pallet overhang
- Detective irregular or undefined edges like newspaper
- Sensing objects with changing shapes or heights such as pouches or bags
- Detection of falling objects
- Detect objects regardless of textures including glossy foil wrap, damaged trays, etc.
- Confirming presence of objects with changing positions such as board bouncing or moving conveyors
Retroreflective area sensors contain multiple transmitter and receiver elements in one housing aimed at a reflector. This gives you continuous height or width detection over the entire distance from the sensor to the detector!

Photoelectric sensors, also called photoeyes, are used to detect the distance, absence or presence of an object by using a light transmitter and a photoelectric receiver.
There are three main types of photoelectric light systems; through beam, retroreflective and diffused.
A
through-beam photoelectric light sensor has a receiver and a transmitter. An object is detected when the light beam is blocked from getting to the receiver from the transmitter.
With
retroreflective photoelectric sensors the transmitter and receiver are one unit and use a reflector to bounce the light beam back to the transmitter. The object is sensed when the beam is interrupted and fails to reach the receiver.
Diffused photoelectric systems uses the object to transmit the signal back to the reciever. The object is detected when the receiver sees the transmitted source (rather than when it fails to see it).
Marshall Wolf Automation specializes in photoelectric systems and is an industrial automation distributor for all the top lines!
We are Pepperl + Fuchs distributors plus carry IDEC, Baumer Electric, Carlo Gavazzi sensors, SUNX and Visolux sensors.
