E6A2 Encoder

E6A2

  • Wide variety of supply voltages and output forms to match input devices
  • Models with zero index function ideal for positioning applications
  • High resolution models (300 or 360 pulses per revolution) substantially improve measuring accuracy
  • Replaces Omron E6A encoders
  • High response frequency and noise immunity make encoders ideal for factory automation applications
