UO-EM-FG4 Universal Encoder Systems


UO-EM-FG4 (incremental encoder module)

Universal encoder systems

  • Output of speed-dependent square wave pulses
  • 1024 pulses per rotation / HTL or TTL
  • Output signals 0°, 90°, reference pulse and inverted signals
  • Transmission frequency up to 100 kHz / overload display

Incremental encoders

The speed signallers

The incremental encoder modules for detecting speed offer three types of signals: shifted 90 degrees to the basic pulse phase, mechanically fixed reference pulse and inverted signals.
