• Contactless shaft rotational frequency transformation into alternating polarity signal.
  • Sensor output amplitude is directly proportional to mark linear speed.
  • Sensor output frequency corresponds to mark passing frequency.
  • Toothed wheels, grooves deepings and lugs in any ferromagnetic material can be taken as mark.
  • Differential principle of handling sensor signal exclude influence of electromagnetic noises on accuracy of rotational frequency to output signal transformation.
  • Sensors are produced in M24×1,5 housing with connector for external circuits or built-in oil- or heat-resisting cable.
  • Measured device – electronic tachometers TE-6K-TK-2-24V-D, TE-6K-TK, tachometric indicator TI-TK.
