For non-contact detection of metallic targets
For non-contact detection of metallic targets at ranges generally under 50mm (2 inches). Inductive proximity sensors emit an alternating electro-magnetic sensing field. When a metal target enters the sensing field, eddy currents are induced in the target, reducing the signal amplitude and triggering a change of state at the sensor output.
Our inductive global sensors for object detection are robust and reliable. With a wide range of over 500 offerings, we offer the right inductive sensor for every application.
The global Inductive sensors are standardized and available worldwide, with an optimum price/performance ratio that offers a sensor solution that is readily available.
Inductive mini-sensors are ideal for position sensing in small compact applications. Balluff miniature sensors offer fully integrated electronics making external amplifiers unnecessary.
Their low weight of 0.7 g permits applications with extreme accelerations. Making them a great choice for high speed applications.
Balluff Inductive mini sensors are characterized by an optimum price/performance ratio. They are easy to install and can be fully integrated even in narrow assemblies such as linear slides, valves and actuators. As a result, position sensing is now possible where there was never before space for a sensor.
Inductive mini sensors are available in ultra-small diameters: including 3 mm though 6 mm.
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.
Sense all ferrous and non-ferrous metals at the same sensing distance Ideal for use in applications where sensors encounter high levels of magnetic interference from sources such as transformers, motors, drives, or welders. Factor 1 sensors incorporate a Balluff-developed multi coil design that enables them to sense all metals – both ferrous and non-ferrous – at the same distance. Standard M8, M12, and M18 sizes are available in the tubular style and 40x40x40 mm in block style.
Factor 1 sensors were designed with welding applications specifically in mind. The PTFE coating helps protect the sensor from weld spatter and weld flash generated during the welding process. Additionally, Balluff currently offers many Factor 1 models with weld resistant coating applied to the face of the sensor, this coating is a major advance over PTFE coated sensors. Beyond their enhanced application flexibility, Balluff Factor 1 sensors also provide the opportunity to standardize on a smaller number of sensor designs, which can lower supply chain and tool crib stocking costs, especially for welding operations. They also offer attractive pricing advantages because they are positioned between standard and weld-field immune products.
In the wide range of hydraulic applications, high pressure proximity sensors are exposed to many aggressive media and hostile environments.
Balluff offers a world-class line of pressure inductive cylinder sensors to service high pressure applications. Designed to withstand severe duty, Balluff high pressure sensors deliver reliable switching performance under demanding industrial conditions.
Corrosion-resistant housing materials, high-strength ceramic sensing faces, and special sealing techniques allow dependable service up to 500 bar according to the sensor type.
All Balluff high pressure sensors are rated for continuous operation in ambient temperatures up to 80º C, with some versions also high temperature rated up to 120º C.
Balluff harsh environment sensors can resist the most extreme cleaning processes. In the food and beverage industry, chemical industry, and even in handling technology, inductive proximity sensors are cleaned with increasingly aggressive methods. Whether they are faced with acids, alkalis, steam, foam cleaners, or high-pressure cleaning equipment, these stainless steel sensors are especially suited to heightened demands.
Balluff analog voltage, current or IO-Link sensors in square configuration test not only the presence of metallic objects. They can also reliably differentiate between parts of varying shapes and sizes and precisely determine distances. Using their analog or digital linear characteristics, the sensors can be used for clamping force measurement or to measure imbalances.
The multiplicity of available configurations allows the inductive distance sensors to be easily integrated into any applications. The sensors work motionlessly and are wear-free and, therefore, distinguish themselves by a long service life.
Our BAW analog voltage, current or IO-Link sensors test not only for the presence of metallic objects. They can also reliably differentiate between parts of varying shapes and sizes and precisely determine distances. Using their analog or digital linear characteristics, the sensors can be used for clamping force measurement or to measure imbalances or for implementation of a soft stop in the cylinder.
The Teach function offers an adjustable linearity 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.
The sensors work motionlessly and are wear-free and, therefore, distinguish themselves by a long service life.
Weld field immune inductive sensors are used for work-piece positioning in welding areas where strong magnetic fields influence ordinary sensors oscillator/coil systems. This leads to false switching when no target is present. Balluff weld field immune inductive sensors can be mounted in the direct vicinity of welding tongs or electrodes, since welding currents of up to 100 kA do not affect the switching function of the sensor.
For error-proofing and part-present applications in heavy manufacturing, inductive sensors are often - by necessity - placed directly in harm’s way. Impact, abrasion, and particulate erosion can destroy conventional plastic-faced sensors and their thin metal bodies. Balluff steel face sensors are designed and built tough to survive longer in your most abusive applications. Machined from solid stainless steel bar stock, steel face sensors can extend life expectancy where blunt impact, abrasion, and erosion quickly bring standard sensors to their knees. Balluff steel face sensors are available in 1X standard range and 2X or 3X extended range, along with special variants like PTFE-coated housings to repel weld spatter, and ferrous- or non-ferrous-selective electronics to sense a variety of different metals.
Specify steel face sensors for the toughest applications to ensure high-throughput, trouble-free production. Retrofit existing production lines with rugged steel face sensors to gain back lost productivity, cut maintenance requirements, reduce sensor replacement costs, and boost overall plant productivity.
The ultra-high temperature-resistant inductive sensors can be used at temperatures of up to 160 ºC. These sensors are ideal for harsh environments in the steel industry, in plastic injection molding machines, and in forging and foundry processes.
