Robust sensors for object detection in metalworking
Inductive sensors are used to manage, position, and control processes in automation technology. The robust sensors detect objects in metalworking.
There are a number of options available to suit most applications: from standard to increased sensing distance, temperature- and high-pressure-resistant.
Inductive sensors are used around the world to manage, position, and control processes in automation technology. Balluff has a wide range of inductive sensors that are pressure-resistant to 500 bar for running end position checks on hydraulic cylinders and monitoring valve positions. They are media-resistant and available in a wide range of housing and thread sizes.
One particular range of these sensors can be used in areas where an explosive atmosphere rarely occurs. Combined with a Zone 2 isolating amplifier, the sensors can also be used in potentially explosive systems or spaces in Zone 1.
Our BAW inductive distance sensors measure various positions and distances and can also differentiate between various material variants. They work contactlessly and are wear-free and, therefore, distinguish themselves by a long service life.
Their teach function has an adjustable linear range. This allows a quick start-up at first installation and provides for short down times during sensor exchange.
The multiplicity of available configurations allows the inductive distance sensors to be easily integrated into any applications. Included among the important fields of application are the monitoring of movements in joining, pressing or clamping equipment used for machine construction or the detection of imbalances and expansions of axles.
The clearance sensors supply an absolute analog voltage, current or IO-Link signal.
The BIP inductive positioning system is also impressive in constricted installation conditions: perfectly integratable, it measures the position of metallic objects with maximum precision in a contact-free, and, therefore, wear-free manner. Thus it securely detects linear displacement paths for 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 design.
The main field of application for the sensor is the monitoring of drive spindles and clamping devices. Here the inductive positioning system provides for error-free clamping operations. The positioning system can further be used in mechanical engineering for many other applications with linear motion, such as determining punching depth, gripping positions, roller placements, valve positions, etc. High repeatability thus ensures optimal process quality.
Balluff's inductive Factor 1 sensors can be used wherever dissimilar metals must be identified uniformly and with high precision. Our all-rounder for reliably recognizing all metals without a reduction factor at a sensing distance: ferrous and non-ferrous metals, steel, brass, aluminum etc. Additionally, they are magnetic-field-resistant and can therefore be used in areas with a strong electromagnetic field – for example in welding plants. For these, we also offer variations with PTFE coatings, the PTFE coating helps protect the sensor from weld slag and weld flash generated during the welding process.
Our pressure-rated inductive sensors withstand a pressure of up to 500 bar. They are, therefore, perfectly suited for position monitoring of your hydraulics, for example: end position verification of hydraulic cylinders or monitoring valve position. This 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 program with different housing diameters and thread sizes.
Our hygienic sensors are extremely resistant to abrasives and aggressive media, their labeling is resistant to abrasion and chemicals. The luminous displays are protected against destruction and the housing construction is optimized for safe cleaning. For use in extremely aggressive environments, variations completely in PTFE are available.
Our magnetic-field-proof inductive sensors are ideal for use in areas with strong magnetic fields such as in welding and induction hardening installations. They are resistant to magnetic fields arising from electric welding currents to 25 kA. With their additional ceramic coating, they are resistant to metal spatters, slag and combustion residues. This also enables the highest precision work in every area of use. The high robustness of our sensors can reduce your maintenance costs – and thus decrease the down time in your facilities.
Balluff's especially resistant stainless steel inductive sensors are custom developed for use 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. For use in welding applications, we offer additional varieties with PTFE and ceramic coating against welding spatter. The extreme resilience of our sensors can reduce your maintenance costs – and thus increase the availability of your facilities.
Our temperature-resistant sensors are designed for temperatures to 160 °C. The housing as well as the cable construction are optimized for higher temperatures,with the electronics completely integrated. Some variations are available as high pressure sensors which makes use even more flexible, therefore you reduce maintenance costs, increase your process quality and optimize your system availability.
Our inductive Global sensors for object detection in metal areas are robust and reliable. With a wide range of over 500 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 large quantities in a short amount of time.
Inductive mini-sensors guarantee position sensing in rough environments and in the tightest of spaces. This is because their electronics are fully integrated, making external amplifiers unnecessary.
Their low weight of 0.7 g permits applications with extreme accelerations. Pick-and-Place is easy to achieve as a result.
Inductive mini-sensors from Balluff are easy to install and can also be fully integrated into slim assemblies. As a result, using them for position sensing is possible where there had never been space for a sensor before. And assemblies can be further reduced in size.
Balluff provides mini-sensors with particularly small diameters: 3 mm, 4 mm and 5 mm. With a housing length of only 6 mm, our compact mini-sensors are the shortest inductive sensors on the market.
