Photoelectric sensors with separate transmitter and separate receiver are placed in opposite of each other. When an object interrupts the light beam, the output. Three sensing modes of photoelectic sensors are thru-beam, retro-reflective and diffuse. They can detect objects at longer distances than other sensing. di-soric through beam sensors have been developed for the most different applications. Functional highlights like a sturdy housing and a compact design feature.

Their multitude of parallel beams enable them to detect objects within a wide window.

Through beam sensors - di-soric

At the same time, our optical windows ensure uniform resolution at every point within the frame. Optical windows from Balluff are available in dynamic and static variants.

The dynamic version only recognizes moving thru beam sensor within the active area without being influenced by feeder devices. They're ideal for thru beam sensor and counting quickly-moving, jumbled items.

Features Uniformly high resolution over the whole area of the frame Detection of small parts with a diameter of up to 0. Light grids Count objects and measure large areas Our BLG light grids are ideally suited for scanning large areas, counting parts, detecting stack heights of paper, for exampleor for measuring the height of pallets.


They are superior thru beam sensor classic through-beam sensors that typically only scan specific points. The light grids from Balluff feature a switching output — for counting, for example — and an analog output for measuring tasks.

Features Also suitable for large objects with a range of up to 2.

Light bands Identify parts, determine positions, and count objects — with high precision Our multi-functional, high-resolution BLA light band unites up to three different parallel measurement results in one device: You can identify parts, determine positions, and count objects.

Numerous measurement modes are available such as testing object diameters, positions, gap widths and positions, edge positions, and object quantities.

The continuous and homogeneous light band is produced by a powerful red-light thru beam sensor and is highly visible.

Up to six different objects over digital outputs can be taught in and displayed using the intuitive control panel. Features Robust metal housing for stable mounting and precise alignment Light band with a width of 50 mm Thru beam sensor to 2 m distance between transmitter and receiver Excellent resolution from 0.

Color sensors Reliably determine color and contrast — better than the human eye Simplify and accelerate your automated processes with the versatile BFS color sensors from Balluff.

Use for recognizing color nuances in textiles, on thru beam sensor sheets, as well as colored markings on packaging or labels.

Our color sensors sort out reject parts and ensure uniformly high product quality. In thru beam sensor manner, they contribute to a reliable production process. Balluff's TrueColor sensors see like the human eye with a higher resolution.

Laser Thrubeam Sensor

The sensing method is identical to that of Through-beam Sensors and some models called Slot Sensors thru beam sensor configured with an integrated Emitter and Receiver.

Features Stable operation and long sensing distances ranging from several centimeters to several tens of meters. Sensing position unaffected by changes in the sensing object path. Operation not greatly affected by sensing object gloss, color, or inclination. Diffuse-reflective Sensors Sensing Method The Emitter and Receiver thru beam sensor installed in the same housing and light normally does not return to the Receiver.

When light from the Emitter strikes the sensing object, the thru beam sensor reflects the light and it enters the Receiver where the intensity of light is increased. This increase in light intensity is used to detect the object. Features Sensing distance ranging from several centimeters thru beam sensor several meters.

The intensity of reflected light, operating stability, and sensing distance vary with the conditions e. Retro-reflective Sensors Sensing Method The Emitter and Receiver are installed in the same housing and light from the Emitter is normally reflected back to the Receiver by a Reflector installed on the opposite side.
