General - The measuring system comprises a MiniCODER and a precision target wheel for attachment to shafts - The MiniCODER contactlessly scans the precision target wheel using magnetoresistive sensors and acquires the direction of rotation, rotational speed and position Features - Output signal level 1 Vpp Differential signal (sin/cos) or TTL / RS422 - Analogue or digital reference pulse - Selection of interpolation factors to increase the number of pulses per revolution possible - Recording of temperature and rotational speed histogram and automatic calibration possible - Frequency range from 0 to 200 kHz - Temperature range -40 °C to +120 °C - Protection class IP 68 - Safety integrated certificate (signal pattern K) Advantages - Maintenance and wear-free - Low temperature drift and high signal quality - Highest immunity to interference due to fully screened metal housing - High design flexibility due to custom manufacture of precision target wheels Field of application - Machine tool engineering - Position and rotational speed acquisition in HSC spindles (High Speed Cutting) - Electronic synchronisation of screw spindles in vacuum pumps - Position and rotational speed measurement in lathes, grinding and milling machines - Rotational speed and position measurement in test stands and motors (hybrid drives, torque motors)
