Magnetic Encoder

The Digital Power & Motion MagEnc1 is a Magnetic Encoder designed to track the position of a linear/strip or circular/ring magnet of alternating poles.  It has the following specifications:

  • Modbus RTU serial communications over RS-485.
  • 5VDC input.
  • 4-wire interface.
  • Sensing distance or air gap to 0.25" using 0.09" Plastalloy magnetic strips from Electrodyne.
  • Dynamic range of +/- 32767 counts (greater counting range possible with software change).
  • Magnetic pole spacing range of 0.025" to 0.250".
  • Position resolution to 0.025" possible.
  • Small size of 1.08" x 2.27" x 0.13" allows mounting in tight quarters.
  • 12" cable with quick-disconnect connector.
  • LED indicator for visual feedback of proper operation (flashes with alternating poles).
  • Multiple encoders can exist on the same bus.
  • Direcly interfaces to EVFD10 Embedded Variable Frequency Drive for position and speed feedback.
