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 also comes in a cuboid configuration. 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 pressures up to 500 bar. They are 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 a comprehensive range of product configurations 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 uniformly identified with high precision. An all-around reliable sensor for 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, making them useable in areas with a strong electromagnetic field – such as welding plants. We also offer variants with PTFE coatings for protection against welding spatter.
The resilient stainless steel BES inductive full-metal sensors have been specifically developed for applications in harsh environments. The housing and sensor front are manufactured from stainless steel. The robust active surface is resistant to impacts, mechanical stresses, and abrasive media. We offer additional variants with PTFE and ceramic coating against welding spatter. The extreme resilience of our sensors can reduce your maintenance costs,thus increasing 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 resistant to magnetic fields arising from electric welding currents of up to 25 kA. They are up to the task with their resiliant ceramic coating, resistant to metal spatters, slag, and combustion residues. Their extreme robustness reduces maintenance costs, which increases system availability. This enables the highest precision work in every area of use.
Increase the availability of your systems while reducing maintenance and storage costs. 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-series temperature-rated inductive sensors can withstand ultra-high temperatures up to 230 °C. Depending on the version, both the housing and cable construction are designed for elevated temperatures. The electronics are fully integrated and can be easily connected to appropriate accessories.
Several form factors allow these sensors to be easily integrated into various situations, even those where space is at a premium. Some versions are also available as high pressure-rated sensors. This represents a significant expansion to the range of applications.
We offer inductive sensors for all Ex zones. Applications for these wear-free switches range from Zone 2/22, in which an explosive atmosphere rarely occurs (Category 3G/3D), to Zone 0/20, where the greatest explosion hazard is present.
With many sensor styles, we serve a broad range of applications so that you can handle a wide variety of requirements. The comprehensive portfolio includes, for example, pressure rated sensors up to 500 bar or sensors with extended temperature range — all in a variety of housing styles. The appropriate accessories, such as NAMUR switching amplifiers or single-ended cordsets, are also available.
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 are highly reliable, making them 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 greater than 20 mm.
Our BAW inductive distance sensors measure various positions, distances, and can differentiate between material variants. They work without making contact, and so remain distinguished by a long service life free from wear.
The included teach function has an adjustable linearity range. This 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 application. 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, wear-free manner. 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.
