Continuous position feedback and distance measurement products.
Inductive distance sensors

Ideal for applications involving relatively short travel of metal targets, Balluff analog inductive sensors provide precision non-contact position measurement in an affordable family of compact housings. Analog inductive sensors are simple three-wire devices that operate on 24V DC. They provide an electrical output signal that varies linearly in proportion to the position of a metal target within their working range. The analog output signal is available in either voltage or current.

Photoelectric distance sensors

Distance measuring photoelectric sensors typically provide a dynamic continuous analog output signal, in some cases a digital output can be activated as well, that relates to object position. These sensors emit either a visible red or laser light that reflects back to the sensor. Some models utilize triangulation, based on the angle of the light reflected on the sensor receiver from the target, to determine the distance to the target. Longer-range models use time of flight, which measures the time it takes a pulsed light from the emitter to return to the receiver sensor after it is reflected off the target. Time of flight sensors offer longer ranges, up to 6 meters, whereas the triangulation method offers higher resolution, as low as 20 micrometers.

Micropulse transducers

Balluff Micropulse® magnetostrictive linear position transducers provide highly accurate and reliable position control signals. Balluff’s non-contact magnetostrictive technology means performance does not degrade over time, as with linear potentiometers. Micropulse® transducers have proven themselves in demanding industrial position monitoring and measurement applications.

Magneto-inductive position sensors

The compact SmartSens magneto-inductive position sensor is for the linear, contact-free position detection of a magnetic target.

Inductive Proximity Sensors

The monitoring of hydraulic, pneumatic, vacuum and various machine gas and liquid pressures is extremely critical in today’s automation processes. Balluff’s pressure sensors exceed the demands of your applications from the ease and flexibility of installation through the simple configuration of the outputs even under the most demanding conditions. Balluff’s attention to quality, superior sensor design, and performance means better reliability, less down time and higher productivity.

Photoelectric Sensors

Photoelectric sensors provide non-contact accurate detection of targets. They emit infrared, red or laser light and the target breaks the light beam or reflects the beam back to the sensor to activate the sensor output. Photoelectric sensing modes are divided into three primary types, those being through-beam, retro-reflective and diffuse. Photoelectric sensors can check for presence, color, distance, size, shape, and many more targets attributes. They can perform these functions at longer distances than other sensing methods while providing numerous mounting options and flexibility.

Capacitive Sensors

Capacitive sensors detect most objects and the fill level of non-conductive materials, liquids, pellets, and powders directly or through a non-metallic container wall.

Magnetic Field Sensors

Today’s pneumatic cylinders are compact, reliable, and cost-effective prime movers for automated equipment. Unfortunately, they are often provided with unreliable reed or Hall Effect switches that fail well before the service life of the cylinder itself is expended. Balluff’s magnetic field cylinder sensors are based on non-contact, solid-state sensor technology that is compatible with both reed and Hall Effect magnetic pole orientations, making them the ideal replacement for standard magnetic switches. Electrically rugged, they feature short circuit protection, overload protection, and reverse polarity protection. Balluff’s magnetic field sensors will work with magnetic strengths as low as 15 Gauss unlike the reed and Hall Effect sensors that require Gauss ratings two times higher or even more. This means that as the magnet weakens from time, heat, and other factors, the Balluff sensor will continue to perform reliably. How sure are we the Balluff sensor is better…they are backed by Balluff’s exclusive LIFETIME warranty.

Tubular Magnetic Field Sensors

In comparison with inductive sensors of the same size, magnetic sensors offer a higher switching distance. Non-ferrous metal and aluminum walls do not impair their switching behavior. These sensors are not sensitive to vibration and can be mounted at the front or side. The magnet is installed flush in steel and the sensors feature both north- and south-pole detection. Our range of magnetic sensors have the ideal sensor for every single cylinder type. Their main task area is the detection of piston positions for pneumatic and hydraulic cylinders.

Ultrasonic Sensors

Whether your application is position detection, distance measurement, or the detection of solid, powder, or liquid media: BUS ultrasonic sensors are precise all-around performers. They remain high-performance independent of color, transparency, and surface properties. Even poor lighting conditions and dark, transparent, or highly reflective objects pose no problem. Ultrasonic sensors show their true strength when long operating ranges with high accuracy are needed. In dusty, humid, and hazy environments, they are sometimes the only alternative. Even in the case of heavy debris, BUS sensors have proven themselves.

Mechanical Sensors

Mechanical sensors are used for positioning and limit switch tasks on machine tools and presses, flexible production centers, robots, assembly and conveying equipment, and in machine and plant construction. For decades, they have proven their worth as the traditional strongmen of automation.

Discrete I/O, analog channels, and valve control over an industrial network with all cables required for controls applications.
Industrial Networks

You can gain significant advantages when evolving to more technical I/O architectures. When moving from hardwired I/O to distributed I/O you gain faster setup/tear-down and shorter cable runs and everything becomes easier to troubleshoot. When transitioning from distributed I/O to network I/O, you gain all of the benefits of distributed I/O plus easier setup repair in the hardware side and easier troubleshooting from diagnostic data in the software side. Finally, if you move from networked I/O to decentralized I/O using IO-Link you gain more diagnostic as well as the ability to change parameters of smart devices on the fly.

Distributed Modular I/O (IO-Link)

Think of a remote “slice” I/O solution. In a typical application, the communication head and the power supply sit on the left hand side and are followed along the backplane by the individual I/O devices, such as discrete 24V input cards or 0-10V analog cards. Usually there are a limited number of slots available in the backplane and individual slices of control components can be inserted. In a similar fashion, a Distributed Modular I/O system has a communications head that talks over the desired industrial network on one side and the right hand side acts as a data collector. In lieu of a backplane, each device is connected to an industry standard M12 port utilizing a basic 3-wire sensor cable for IO-Link communication. With the ability to be installed within a 20 meter radius from the data, collector devices can be easily distributed across the machine. The backplane of Distributed Modular I/O = Utilizing a widely accepted and open point to point technology, IO-Link, a Distributed Modular I/O system is fieldbus independent, is easily configured and is vendor neutral. Process data shows up as simple packets of bytes in the controller for easy integration. The parameterization data allows the devices to be quickly configured using simple read/write commands, and best of all, there is no “sub-bus” to cause headaches, nor is there some new protocol to be educated on. The digital signal is carried over pin 4 of a standard cable and 24V power is provided to the device in a standard configuration. If required, the IO-Link port can be used for a standard I/O point.
