The Balluff GmbH develops, manufactures and markets a wide range of sensors for factory automation. Balluff Sensors Worldwide in mechanical engineering and automobile production are used. The Balluff product range includes electro-mechanical limit switches, inductive proximity sensors, electro-mechanical switching mechanisms, optoelectronic sensors, linear and rotary displacement transducers, inductive identification systems and capable sensors.


Inductive sensors

Balluff inductive sensors are used for controlling, regulating, automating, positioning and monitoring of workflows. They are robust sensors that detect the presence of a metal part.

They are contactless and have an electronic output, ie they are wearing.

Optoelectronic sensors

The extensive program of Balluff photoelectric sensors is used in many applications of robotics, automation, assembly and handling. Each family has its focus on its area and is an excellent specialist.

In addition to cylindrical shapes from M12 to M30, metal, stainless steel and plastic, Balluff offers numerous versions in cubic boxes made of plastic or metal in nearly all sizes with different features and performance.

Magnetic field sensors

Magnetic field sensors respond to an external magnetic field. Its main application is the detection of piston positions on pneumatic cylinders. Depending on the type of sensor has a housing made of polyamide, PBTP, GF-reinforced, or at the sweat-resistant versions of anodized aluminum.

Capacitive Sensors

Capacitive sensors evaluate the change in capacitance caused by the intrusion of an object in the electric field of a capacitor. It follows that the capacitive sensor detects not only metals but also non-conductors, provided the dielectric constant is sufficiently large. Dimensioned according to the capacitive sensor is also able, by certain non-metallic materials through it.

Mechanical Sensors

Electromechanical sensors are electro-mechanical position switches and rotary cam switches with electro-mechanical and inductive switching elements. They serve as non-contact control devices and automatic controls to limit positioning of machine tools and flexible machining centers, robots, assembly and conveyor systems in the automotive industry and the general mechanical and plant engineering.



Balluff Micro Linear Transducer in Profile Housing are by their design, the high level of protection and ease of assembly is an alternative to linear position transducer, such as potentiometers, glass scales and LVDT. The test section is protected in an extruded aluminum profile. The measuring point is marked with no-contact energy supply through a passive position sensor on the measuring section.

Identification Systems (RFID)

Balluff identification systems are indispensable aids TO cope with the flood of information in modern factories. The right information at right time at right place: this requirement is met consistently through the integration of BIS. The code stores all the information carrier, which are available at any decision point on demand.

Remote Systeme

The use of remote systems is a proven solution wherever hardwired sensors can not be used, eg on rotary tables and interchangeable stamping heads. The sensors make the movement of machine parts, on which they are mounted with. The sensors are wired to the transmitter.


In the computer-controlled production of material and information flow are inextricably linked. This consistent coupling is now necessary for flexibility and efficiency in automation. BUS Systems ensure a reliable exchange of information between material flow and data processing for all areas of manufacturing, in which material is moved.

Inductive sensors

Bernstein inductive sensors are used for controlling, regulating, automating, positioning and monitoring of workflows. An inductive proximity sensor basically consists of four functional groups: a coil, an oscillator, a threshold switch and a switching amplifier with short circuit protection.

Capacitive Sensors

Capacitive proximity sensors detect conductive and nonconductive materials, which can be in solid or liquid state. They are monitoring the level measurement in tanks, the content test for filling and packaging systems, the detection, positioning, and counting of objects, for example, to sequence control, conveyor belts and roller.

Magnetic sensors

Bernstein offers a further addition to the electro-mechanical solenoid switch range electronic versions according to the Hall and magnetoresistance principle. Electromechanical and electronic magnetic switches have special characteristics that permit optimal use in the environmental conditions for them.

The electronic versions are characterized by improved mechanical properties (extreme insensitivity to vibration, shock or impact) and are completely free from wear. The "classic" electromechanical magnetic switches through the use of a single "active" component (Reed contact) and offer extremely reliable and low cost by Allstromtauglichkeit universal application.


In the construction industry, agricultural machinery, commercial equipment and industrial trucks are increasingly tilt switch and tilt sensors. With inclination sensors, position data are recorded as, for example, tilt and evaluated via an analog output.

Opto Sensors

The opto-electronic sensors from Bernstein are fundamentally different in the three different function or operation modes:

  • Through-beam
  • Retroreflective
  • Diffuse reflectance.

The sensors are used in the EN 60947-5-2 referred to as "photo-electric proximity switches" and are CE compliant. The use of the system depends initially on the application and all associated boundary conditions.

Opto-Electrical safety components

Recklessness and innocence are human - all too human. Therefore, protection of facilities Bernstein offer reliable protection of operating personnel from hazardous machinery products in production environments. Best Example, the non-contact safety light curtains and multiple light beam safety light curtains. This secure barrier-free entrances, which are essential for the efficient production process.

Sensors are technical components, the physical or chemical properties such as: can temperature, light, humidity, pressure and the material nature of its environment collect qualitative or quantitative. These variables are measured by physical or chemical effects, and converted into electrical signals. For the measurement technique is used in DIN 1319-1, the term transducer measurements.

Sensors can be classified according to size and production technology as well as on the use and purpose. A distinction is sensors according to their mode of action during the forming of the sizes in passive and active sensors.

In the art sensors in automated processes play an important role as signal transducer. Be covered by them values ​​or states, usually electrically-amplified electronically, in the corresponding control processes, which triggers the appropriate action. In recent years, the subsequent signal processing is performed increasingly in the sensor. Such sensors include a microprocessor or a micro-system and have intelligence, so they are also known as a smart sensor.
