  • GEL 2444T- 2444K – 2444D MiniCoder with TTL or SINCOS output

The GEL 2444 MiniCODERs are available in three variants, the GEL 2444-T sensor that generates a square wave output, the GEL 2444-K sensor that generates a sine wave output and the GEL 2444-D that generates square wave output and a rotational speed histogram. The output signals are generated from teeth on a ferro-magnetic tooth-wheel passing the sensing head. This measuring principle has found applications in machine tool spindles (including HSC high-speed-cutting spindles), electric motors, gearboxes and a wide range of other applications.

Due to the contact-free operating principle, applications to over 70,000rpm have been realised and the electronics comply with the “safety integrated” standard for numerical control applications.

Highlights
  • Maintenance and wear-free
  • Low temperature drift and high signal quality
  • Versions T and D available with internal interpolation up to a factor of x 32
  • Highest immunity to interference due to fully screened metal housing
  • Records the minimum temperature, maximum temperature and rotational speed histogram
  • Can be calibrated automatically using the testing and programming unit
  • Amplitude control
Applications
  • Speed detection in HSC spindles (High-Speed-Cutting)
  • Measurement of speed and position of milling and grinding spindles in machine tools for the machining of metal, wood, glass, stone and aluminium
  • Angle measurement in radar equipment
  • Electronic synchronization of helical spindles in dry-running vaccum pumps
  • Measurement of speed in test stands
