Robust and with high-resolution
Magnetic encoders

Our incremental encoders sense a gear magnetically, that is, in a contact-free manner. The result is a robust, contamination-resistant, long-lived solution for the precise measurement of angle and speed, e.g. in drive motors for machine tools and test benches.

By using closed metal housings and a powerful bias magnet system, our encoders are characterised by their high resistance to mechanical, electrical and magnetic interference. This type of interference can include: Vibration, shock, ESD influence or external magnetic fields in synchronous motors.

Advantages

  • Magnetic, contact-free probing of gears of steel
  • Analogue 1 Vpp SIN/COS output signals
  • Alternatively: TTL or HTL signals
  • Signal replication using built-in interpolation electronics
  • Automatic stabilisation of amplitudes
  • High-resolution measurement of speed and angle rotation up to more than 100,000 rpm
  • Suitable for HSC applications (High Speed Cutting)
  • Recognition of direction of rotation
  • Temperature-stable up to 100 °C (option up to 120 °C)
  • High EMC and ESD resistance (up to 30 kV)
  • I2C interface for adjustment of signal parameters as needed
  • Robust metal housing
  • Certified as safety integrated

Accessories

To implement custom requirements, the user has a diverse selection of accessories available:

  • Measurement gears: Modulus M = 0.3 or M = 0.5 in standard variant or to specification
  • Design of the sensor housing: different standard variants or according to customer specification
  • Different types of signal lines and temperature cables
  • Connection kit: different standard variants or according to customer specification
  • External converter boxes, e.g. for signal digitalisation or replication (interpolation)
  • USB boxes for adjustment of signal parameters via I2C interface as needed
  • USB measurement boxes for quality control and mobile service to analyse sensor signals and gear quality

Product continuity

Magnetic gear wheel encoders are characterized by their long service life. If a spindle is repaired today, it can very well be the case that the corresponding encoder has already been retired. On the other hand, it can also happen that you want to continue production of a spindle of a popular design, but the matching encoders are no longer available for purchase. For these cases, VS Sensorik offers a variety of encoders that secure your product continuity in the future as well:

  • VS Sensorik: Sensors in the MGK2M, KWG2M, KWG2D and RGK2M series are still available, or there are mechanically compatible variants available
  • Siemens: For the sensors in the SIZAG and SIMAG series, there are mechanically compatible designs available
  • Sensor compatibility with all current gear types with a modulus of M = 0.3 or M = 0.5, particularly in terms of the design of the reference marks
  • Encoders for gears with a modulus M = 0,8 or M = 1,0 are available (e.g. replacement for FP-210)
