Magnetic Field Sensors

BMP magnetic field positioning systems

Intelligent linear feedback

BMP magnetic field positioning systems give you the ability to monitor running processes reliably and wear-free. They help you stay in control of various processes, ensure simultaneous processing of workpieces while remaining energy-efficient. Their use ensures high process reliability and automation quality. And it all happens reliably, whether you need to control assembly in the automobile industry, or quickly adapt to changing formats and process parameters in the packaging industry while controlling multiple pneumatic motions at the same time.

Features

  • Modular design for flexibility: covers a variety of cylinders over a stroke of up to 256 mm
  • Continuous monitoring of the piston position in the smallest spaces using analog voltage and current output as well as an IO-Link interface
  • Reliable results with application-specific linearity and repeat accuracy
  • High process reliability: low temperature drift and very good electromagnetic compatibility
  • Ready for the IIoT: format changes, condition monitoring and predictive maintenance

BMF magnetic field sensors for T-slot

For flush mounting – securely held

Our magnetic field sensors detect piston position contactlessly through the cylinder wall. Our magnetic field sensors for T-slots can be mounted directly in the slot and provide a particularly strong hold. They mount flush so that they are suitable for space-critical applications.

For use in harsh environments, around weld spatter or flying sparks, we offer versions in a metal housing or with magnet-sensitive electronics for industrial environments with high welding currents. And extremely short form factors open up extra play allowance when used.

Features

  • Reliable switching process thanks to precise switching points
  • Contact-free and therefore wear-free
  • Insensitive to contamination
  • Thanks to the especially bright LEDs, they reliably display the switching state of the sensor
    even at a long distance

BMF magnetic field sensors for C-slot

For flush mounting – securely held

Magnetic field sensors detect piston position contactlessly through the cylinder wall. Our magnetic field sensors for C-slots can be mounted directly in the slot and provide a particularly strong hold. They mount flush so that they are suitable for space-critical applications.

Since all our C-slot sensors can be inserted from above, they will also fit where the slot ends are closed off. We also offer extremely short designs that perfectly fit grippers and short-stroke cylinders.

Features

  • Reliable switching process
  • Precise switching point
  • Contact-free and therefore wear-free
  • Insensitive to contamination
  • Low hysteresis

BMF magnetic field sensors for multiple slot shapes

For universal use

Our magnetic field sensors with flexible attachment systems are suitable for all groove shapes, such as T-, C-, round, or trapezoidal slots. They can be adapted to almost all cylinder types using special manufacturer-specific mounting brackets. As a result, a reliable tool is always available for detecting position on grippers and pneumatic cylinders. And they are highly flexible.

Moreover, the switchpoint is adjusted only once and is retained even if the sensor is replaced. This way you increase the functional reliability of your equipment. Sensor replacement is safer and easier even in hardto-reach places. A welcome side-effect: our universally applicable sensor types save you inventory space and money.

Features

  • One sensor for all pneumatic cylinders
  • Reliable switching process
  • Captive switchpoint
  • Contact-free and therefore wear-free
  • The best hold thanks to metal fasteners

BMF magnetic field sensors for trapezoidal slot and trapezoidal guide

Ingenious fastening concept

Our magnetic field sensors for trapezoidal grooves and trapezoidal guides can be mounted easily to the cylinder with mounting brackets and adapters. The sophisticated mounting bracket concept is suitable for most types of cylinder like these.

In addition, we offer sensor variants that fit directly on a cylinder with a 60° and 90° trapezoidal slot without a mounting bracket. The sensors detect piston position contactlessly through the cylinder walls.

Features

  • Reliable switching process
  • Precise switching point
  • Contact-free and therefore wear-free
  • Insensitive to contamination
  • Simple to install

BMF magnetic field sensors for round cylinders

Secure mounting with mounting bracket and hose clamp

Our magnetic field sensors for round cylinders are securely integrated into different applications with the appropriate hose clamp and mounting bracket. The well thought-out mounting bracket concept is suitable for most types of cylinder up to 80 mm piston diameter. Piston position is registered contactlessly through the cylinder wall.

Features

  • Up to 80 mm piston diameter
  • Reliable switching process thanks to precise switching points
  • Contact-free and therefore wear-free
  • Insensitive to contamination
  • Firm grip
  • Mounts quickly

BMF magnetic field sensors for tie rod cylinders

Classic mounting system for versatile use

Our magnetic field sensors for tie rod cylinders can be reliably integrated into a myriad of applications. The sensors are traditionally mounted with mounting brackets on cylinders with tie rods and DUO rails. The well thought-out mounting bracket concept is suitable for most current types of cylinder with any piston diameter. The piston position is detected without contact through the cylinder walls.

Features

  • Tie rod diameter up to 17 mm
  • Reliable switching process thanks to precise switching points
  • Contact-free and therefore wear-free
  • Insensitive to contamination
  • Firm grip
  • Mounts quickly

BMF magnetic field sensors with adjustable switchpoints

More flexibility and comfort through adjustable multiple switching points

Our magnetic field sensors for C- and T-slots with adjustable multiple switching points enable quick integration of pneumatic and hydraulic cylinder drives in machine control. Attach our teachable sensors in their approximate position. One or more switchpoints are then set using the teach key. This allows two different switching points to be set on the same cylinder, up to eight with the IO-Link version. One sensor can thus replace multiple traditional sensors. For you this means more convenience, greater flexibility and significant cost savings.

Features

  • Contact-free and therefore wear-free
  • Individual installation of the switching points without tools
  • Applicable for cylinders and grippers with radial or axial magnetic polarization
  • Remote-Teach of up to 8 switching points via IO-Link
  • Adjustable hysteresis for each individual switching point
  • Extremely large, 60 mm travel path
  • Status indication via multiple colored LEDs
  • Captive switching points even after a power outage

BMF single-connector version with two BMF magnetic field sensors

Save mounting costs with only one plug connector for two sensors

Two magnetic field sensors are often necessary for smaller pneumatic hydraulic cylinders or grippers in order to determine the position of the piston. Our single-connector version reduces your installation and wiring effort and expense. The electrical connection for both sensors takes place via a single 4-pin connector. This means you only need one plug position when connecting to a distribution box saving you both time and effort as well as procurement and inventory costs.

Features

  • Tie rod diameter up to 17 mm
  • Reliable switching process thanks to precise switching points
  • Contact-free and therefore wear-free
  • Insensitive to contamination
  • Mounts quickly

BMF tubular magnetic field sensors

Non-contacting as a safe bet

Tubular magnetic field sensors enable you to reliably detect positions in a non-contacting manner. They are vibration-insensitive and switch through non-ferrous metal and aluminum walls without reducing the switching distance. In doing so, they allow for a significantly greater switching distance than inductive sensors of the same configuration size. Another plug: installing it flush in steel is no problem.

Features

  • Small, extremely compact configuration, and very long switching distances
  • Sensors with a diameter of 6.5 mm can scan positions without making contact at a distance of up to 90 mm
  • Industrial grade and impervious to contamination
  • Position detection even through containers or pipes
  • Detection of codes using magnets
