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 emitter and receiver are housed together in a single unit so that you can easily install 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 laser red light. Their scanning response 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, 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 it and align it quickly with its generous mounting tolerances.

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 with absolute reliability.
Our fork sensors with transmitter and receiver in one housing are pre-adjusted. That reduces your expense, saves valuable time during start-up and supports reliable processes. When it comes to accuracy, small parts and detail detection, and operating reliability, our fork sensors are unsurpassed. The broad product offering also ensures reliable solutions even for challenging applications such as transparency detection, water detection and web edge control.
Angle sensors are used for demanding applications – for example, in feed monitoring of objects or in counting and detection in complex feed systems. The form factor and beam geometry enable the approach and detection of objects from almost every direction.
They are quick to install – even in tight mounting spaces. because the emitter and receiver are permanently aligned with each other.
Our optical window sensors are useful where objects are to be checked not only at discrete points, but also within a range. Thanks to their multitude of beams arranged in parallel, they can detect objects within a broad window. Optical window sensors are available in a variety of dynamic and static versions. The dynamic version detects only moving objects. Feed equipment etc. does not affect detection, so that fast and randomly falling objects can be counted.
Our light grids are ideally suited for scanning larger areas, for counting parts, for detecting stack heights (of paper, for example) or for measuring the height of pallets. This makes them superior to traditional through-beam sensors that typically scan only selectively at points. Balluff's light grids feature a switching output – for counting, for example – and an analog output for measurement tasks.
Our multi-functional, high-resolution BLA light bands combines 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 and quantities, gap width and position, as well as edge position. Using the simple and intuitive control panel, you can program recognition of up to six different objects through digital outputs.
Use color sensors to simplify and accelerate your automated processes, for example, in detecting color nuances in textiles or painted sheets as well as colored markings on packaging or labels. They ensure consistently high product quality and contribute to reliable production sequences. The true-color sensors differentiate even subtle color nuances and evaluate the quality of the finished pieces objectively and unerringly.
Contrast sensors are high-resolution diffuse sensors that distinguish objects based on their gray values. Balluff's rugged contrast sensors recognize even small differences in contrast, have a high switching frequency up to 30 kHz and are therefore particularly fast. They enable high positioning precision and are appropriate for a variety of applications, for example, in the printing and packaging industry.
Our luminescence sensors, with their UV light sensor, detect objects that an unaided human eye cannot see. They are useful for detecting invisibly marked products. Or for testing lubricants which have been previously enriched with luminescent particles.
Fiber optic sensors are used where traditional photoelectric sensors are too large or inflexible. Our fiber optic sensors are combined with plastic or glass fiber optics for a complete sensor. This gives you the maximum flexibility for any application. Plastic fiber optics are used for lesser requirements in ruggedness, temperature and chemical resistance, but we also offer high-temperature plastic fiber optics. Glass fiber optics feature non-crush, temperature and chemical resistant properties.
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 these wherever mounting space is at a premium: for example for small parts detection, checking parts features, parts positioning, counting 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 our plastic as well as glass fibers are characterized by their transmission accuracy and speed.
The MicroMote system is especially small and is therefore highly flexible in its uses. It combines an external amplifier with unusually small photoelectric sensor heads. As a result it is suitable even for extremely constricted spaces and moving machine elements. A variety of housing styles ensures especially high design freedom, while precise photoelectric components ensure high process accuracy in 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 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-contact, wear-free sensors use either red light or laser light. 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.
