Highest quality and accuracy for automation
Automation without inductive sensors can hardly be imagined. Wear-resistant, reliable non-contact position detection of metallic objects is required wherever automation is used, whether in mechanical engineering, electronics production, automotive, food, or plastics industries.
Balluff offers a wide range of inductive sensors with diverse designs for nearly any application: from standard sensors to sensors with increased switching distance, hygienic sensors, high-pressure sensors, ex-zone sensors for hazardous areas, and factor 1 sensors. Some sensors have an additional ceramic or PTFE coating so that weld spatter, for example, cannot adhere to them. Sensors that are both factor 1 and all-metal are also available.
Aided by inductive sensors from Balluff, you can automate, monitor, and control processes and conditions at the highest quality, even in extreme environments.
Our BES inductive standard sensors with preferred types for detecting objects in metal areas are robust and reliable. With a wide range of over 500 model series, we offer the right inductive sensor for every application.
The technology, which is in use worldwide, has an optimum price/performance ratio and can also be delivered in a short amount of time even in large quantities.
With inductive 2-wire sensors from Balluff, you can reduce the number of variants in your application in a targeted manner. This saves you storage space and costs without losing functionality. Our standard range of 2-wire technology with a range of 0 to 50 mm includes sensors in M8 to M30 and with cuboid configuration. And it is suitable for most PNP or NPN control systems. Our Inductive 2-wire sensors are also available with increased switching distance.
Our BHS pressure-rated inductive sensors withstand a pressure of up to 500 bar. They are, therefore, perfectly suited for monitoring the position of your hydraulics, such as when controlling the end position of hydraulic cylinders or monitoring valve positions. Their durability is made possible by media-resistant housing materials and a special sealing process. For your individual applications, we offer different configurations as well as a comprehensive range of products with different housing diameters and thread sizes.
Our BES hygienic inductive sensors are extremely resistant to abrasive and aggressive media: Their labeling is resistant to abrasion and chemicals. The indicator lights are protected against destruction and the housing construction is optimized for safe cleaning in such a manner that your product will not become contaminated. Variants in full PTFE are available for use in extremely aggressive environments.
BES inductive factor 1 sensors from Balluff can be used wherever different types of metals must be identified uniformly and with high precision. Our all-rounder for reliably recognizing all metals without a reduction factor at the switching distance: ferrous and non-ferrous metals, steel, brass, aluminum etc. Additionally, they are magnetic-field-resistant and can thus be used in areas with a strong electromagnetic field – for example in welding plants. For these, we also offer variants with PTFE coatings for protection against welding spatter.
The especially resilient stainless steel BES inductive full-metal sensors from Balluff have been specially developed for applications in very harsh environments. Housing and sensor front manufactured from stainless steel. The robust active surface is resistant to impacts as well as mechanical stresses and abrasive media. We offer additional variants with PTFE and ceramic coating against welding spatter for use in welding applications. The extreme resilience of our sensors can reduce your maintenance costs – and thus increase the availability of your system.
Our BES magnetic-field-resistant inductive sensors are ideal for use in areas with strong electromagnetic fields such as in welding and induction hardening installations. They are insensitive to magnetic fields arising from electric welding currents of up to 25 kA. With their additional ceramic coating, they are up to the task with their resistance to metal spatters, slag, and combustion residues. And enable the highest precision work in every area of use. Their extreme robustness reduces maintenance costs and thus increases system availability.
Increase the availability of your systems and reduce maintenance and storage costs at the same time. Weld-immune inductive sensors from Balluff detect metallic objects, such as steel, aluminum, or brass, with the same switching distance. With their ceramic coating they are just as resistant to metal spatter, slag, and combustion residues as they are to magnetic fields arising from electric welding currents of up to 25 kA. Even abrasive media and cleaning agents cannot harm them. Perfect for use in welding, induction hardening installations, and similarly harsh industrial environments.
Our BES temperature-rated inductive sensors are designed for temperatures up to 160 °C: The housing as well as the cable construction have both been optimized for elevated temperatures. The electronics are completely integrated. Some variants are also available as high pressure sensors, which makes using them even more flexible. This reduces maintenance costs, thus increasing your process quality and optimizing your system availability.
Balluff's BES wear-free inductive sensors for potentially explosive areas can be installed in various Ex zones: First, in areas where an explosive atmosphere only occurs occasionally (Category 3G/3D). And secondly, in potentially explosive facilities or spaces in Zone 1 (Category 2G/1D) – then in connection with NAMUR-compatible barriers and transformers. For flexible use, we offer a comprehensive portfolio of common sensor housings and thread sizes. Our sensors come with either hard-molded cables or plug connectors.
Inductive NAMUR sensors and switching amplifiers make it easy to detect conditions within sensitive areas in a non-contacting manner. The sensors are placed inside the work area and the switching amplifiers are placed outside. This assists with process stability.
In addition to standard versions, we also offer high pressure variants for monitoring end positions in hydraulic cylinders or for monitoring the positions of valves. There are explosion-proof variants for potentially explosive systems or rooms in Zones 1 and 2. In addition, proven models are available for applications in the semiconductor industry.
Our inductive ring and tube sensors work extremely reliably and are ideal for detecting small parts with a high object speed of up to 20 m/s. The integrated pulse extension of up to 150 ms makes it possible for the switching signals to be utilized by control systems in a dependable manner. As the user, you also benefit from the simple installation procedure. The sensors can be universally mounted, lined up, and stacked at a distance > 20 mm.
Our BAW inductive distance sensors measure various positions and distances and can also differentiate between various material variants. They work without making contact, are, therefore, free from wear, and distinguish themselves by a long service life.
Its teach function has an adjustable linearity range, which enables quick commissioning during initial installation and ensures short downtimes when replacing sensors.
The multiplicity of available configurations allows the inductive distance sensors to be easily integrated into any applications. Important applications include monitoring movements in joining, pressing, or clamping equipment used for mechanical engineering or detecting axle imbalances and expansions.
The inductive distance sensors supply an absolute analog voltage, current, or IO-Link signal.
BIP inductive positioning systems are up to the task even in tight installation conditions: Perfectly integratable, it measures the position of metallic objects with maximum precision in a non-contacting, and, therefore, wear-free manner. Thus, they reliably detect linear measured displacements via a simple target. A simple component of the machine, such as a rotary disk, can also function as a target. Measured values are relayed via IO-Link or as analog, depending upon the version.
The primary field of application for the sensors is monitoring drive spindles and clamping devices. In this case, inductive positioning systems ensure that clamping processes flow without malfunctions. In addition, the positioning system can be used in mechanical engineering for many other applications with linear motion, such as determining punch depth, grip positions, roller placements, valve positions, etc. High reproducibility thus ensures optimum process quality.
