Photoelectric sensors check presence, shape, colour, distance, and thickness - optimised for robotics, automation, assembly, and handling. They are real experts with various strengths: detecting and counting parts, monitoring stack heights, through-glass detection, aligning small parts, detecting marks, fill level detection, and much more!
The wide Balluff spectrum offers every light type, whether red light, infrared or laser technology, in different ranges. With and without background suppression. Various designs – also in mini version – ensure a wide variety of possible applications. Our photoelectric sensors are optimized for robotics, automation, installation and handling.
Our vast array of diffuse sensors offers an economical solution if you want to reliably detect contrast differences. These diffuse sensors detect objects based on their surface, color, and material. Thus, their scanning range depends on the size, shape, color, and texture of the reflective object surface.
The transmitter and receiver are housed together in a single unit so that you can easily mount the diffuse sensors and align them quickly using their highly visible light beams.
You select the most suitable light type based on your application. Depending on the model, our diffuse sensors offer you highly visible red light, invisible infrared light, or very precise laser light that is ideally suited for detecting small parts.
For color-independent and surface-independent detection, we recommend diffuse sensors with background suppression. They work with red light or the laser red light that is ideally suited for detecting small parts . Their scanning behavior is virtually constant, even with different reflectance levels.
Our diffuse sensors with background suppression detect objects within a set switching distance, without being affected by reflective backgrounds. And it is just about regardless of the color and surface of the object. Object and background can be differentiated very definitively, especially as these diffuse sensors are characterized by their low gray value shift and hysteresis.
Since the transmitter and receiver are housed together in a single unit to save space, you can easily mount our diffuse sensors and align them quickly. In addition, the highly visible light beam with the versions available in red light and lasers make it easier for you to do this. You can easily adjust the settings using teach-in or via a potentiometer.
Whatever your application, Balluff offers you a wide range of retroreflective sensors. These enable you to reliably detect objects regardless of surface, color, and material. If you use a polarizing filter, our retroreflective sensors even enable you to detect shiny objects.
The transmitter and receiver are housed together in a single unit so that you can easily mount this light barrier and align it quickly with its generous mounting tolerances.
You select the most suitable light type based on your requirements. Depending on the model, our retroreflective sensors work with highly visible red light, invisible infrared light, or very precise laser light that is ideally suited for detecting small parts.
Through-beam sensors from Balluff serve to detect objects reliably, regardless of surface, color, material - even with a heavy gloss finish. They consist of separate transmitter and receiver units that are attuned to each other. When an object interrupts the light beam, this causes a change in the output signal in the receiver. Absolute reliability.
Our BGL fork sensors with transmitter and receiver in one housing are already aligned. This reduces the effort on your part and saves valuable time during commissioning and facilitates reliable processes.
In terms of accuracy, the fork sensors from Balluff are unrivaled for small-component and detail detection as well as operational reliability. Achieve the best results with our laser fork sensors – in particular when it comes to precise positioning as well as with secure detection of fast movement sequences and small parts in robotics and automation, for example.
Our comprehensive portfolio also offers you reliable solutions for difficult applications. Or for special applications like transparency detection, water detection, and web edge control.
BWL angle sensors from Balluff are a logical development of Balluff's fork sensors for more demanding applications. Their special housing configuration and beam geometry enable objects to approach and be recognized from almost every direction.
Red light and laser variants guarantee a wide range of application scenarios: Such as, when controlling the feed of flat and large objects, when counting and detecting objects in complex feeders, as well as in a variety of other applications in severe industrial environments.
Installation is very simple even in difficult, confined spaces: The transmitter and receiver are firmly affixed to each other, making expensive brackets superfluous. But that's not all. Even time-intensive adjustments are eliminated.
Our BOW optical windows are useful when objects need to be scanned not just at specific points, but also over an area. Their multitude of beams arranged in parallel enable them to detect objects within a wide window. 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 objects within the active area – without being influenced at all by feeder devices, etc.: Ideal for scanning and counting objects coming through quickly and jumbled.
Our BLG light grids are ideally suited for scanning large areas, for counting parts, for detecting stack heights (of paper, for example), or for measuring the height of pallets. They are, therefore, superior to 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.
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 laser and is highly visible. Up to six different objects over digital outputs can be taught in and displayed using the intuitive control panel.
Simplify and accelerate your automated processes with the versatile BFS color sensors from Balluff: For example, for recognizing color nuances in textiles, on painted sheets, as well as colored markings on packaging or labels. Our color sensors sort out reject parts and thus ensure uniformly high product quality. In this manner, they contribute to a reliable production process.
Balluff's TrueColor sensors see like the human eye – although with better resolution. They differentiate between even subtle color nuances and evaluate the quality of the finished pieces. In addition, they test with a precision that is unaffected by any human failings. Always objective and absolutely incorruptible.
Contrast sensors are high-resolution diffuse sensors that distinguish objects based on their gray values. The robust BKT contrast sensors from Balluff detect even small differences in contrast, have a high switching frequency up to 30 kHz, and are therefore especially fast. They enable high positioning accuracy and are, therefore, suitable for a wide range of applications, such as in the printing and packaging industries.
Our BLT luminescence sensors with their UV light sensor detect objects that a human cannot see without help. They are useful for detecting invisibly marked products. Or if, for example, lubricants are to be tested that were previously enriched with luminescent particles.
BFB fiber-based devices for plastic and glass fibers from Balluff are used when a conventional optical sensor would be too large or two rigid for the application. They can be combined with plastic or glass fiber optics for a complete sensor so that depending on the application, the maximum amount of flexibility is available to you.
Our large selection of plastic fiber optics can be used especially when requirements for robustness or resistance to environmental temperatures or chemicals are not too great. We do, however, have high-temperature-resistant fibers available in our range of products. And with glass fiber optics, we also offer tread-resistant, temperature-resistant, and chemical-resistant variants.
Our plastic and glass fibers, which are designed and tested for our fiber-based devices, are available as switches or in single-use designs. You can use them whenever you have virtually no installation space available: For example, for detecting small parts, for controlling part characteristics, for parts positioning, for counting tasks, and in robotics.
Plastic optics are used when requirements for robustness as well as temperature or chemical resistance are low. Glass fiber optics are suitable for harsh environments – even with oil mist and influence from chemicals – as well as for temperatures of over 200 °C.
Both of our plastic as well as glass fibers are characterized by their transmission accuracy and speed. Various end fittings (diameter from 2 to 8 mm, square from 5 x 4 mm to 23 x 55 mm, …) with straight or angled light emission or even bendable optic heads for plastic fibers round out Balluff's portfolio.
The BOH Micromote system from Balluff is especially small and, therefore, can be utilized in a very flexibly manner. It combines an external processor unit (amplifier) with exceptionally small photoelectric sensor heads. As a result, it is suitable for even extremely constricted spatial conditions and moving machine elements.
The modular system, which consists of Micromote sensors and innovative sensor elements, meets the most individualistic requirements: A variety of housing configurations ensure a particularly high degree of design freedom while precise optoelectronic components ensure maximum process accurately for any application.
Photoelectric distance sensors from Balluff help you with positioning, material flow control, or level detection, as well as in many other applications. Whether in the automotive industry, factory automation, logistics, or in constructional steelwork, you can achieve noticeable increases in productivity through reliable and distance measurement and avoid faults in a targeted manner. With that in mind, we offer various, somewhat adjustable measurement ranges from 20 mm to 20 m and variants with and without background suppression ability.
Our non-contacting, and thus, wear-free sensors function based on the triangulation principle or time-of-flight technology (TOF) and use red light or lasers. They are housed in durable plastic or metal housings and have analog current and voltage outputs as well as digital serial or IO-Link interfaces. Our photoelectric distance sensors are degree of protection IP65/67 and IP69K rated, making them suitable for even harsh environments.
