• Broad range of working temperature, -15 to +120°C, Optimum exploitation of motor capacity
  • Unequalled bandwidth of 500 kHz at full signal quality, Peak speeds and reduction in unproductive downtime
  • Excellent immunity to interference (EN61000-4-4 severity 4)
  • High functional dependability through signal control and system monitoring (undervoltage ,contamination, Disc breakage, End of LED life-time)
  • High signal quality through control and error compensation

The sinewave encoder S21, developed specifically for motor feedback applications, is well known for its broad temperature range from -15°C to +120°C, which enables the motor to be used to capacity more effectively. Thanks to the broad bandwidth of 500 KHz at full signal quality, peak speeds can be achieved, while excellent immunity to interference and high functional dependability through signal control and system monitoring ensure reliable operation.
