ERN 120

Description

The HEIDENHAIN ERN 120 rotary encoders have an integral bearing and a stator coupling which connects directly to the measured shaft. The ERN 120 series rotary encoders offer a high dynamic performance and natural frequencies with the following features…

  • Hollow through shaft options Ø 20mm, Ø 25mm, Ø 38mm and Ø 50mm
  • Single turn encoder
  • TTL quadrature incremental signal
  • Line counts from 1000 to 5000
  • Single reference mark
  • System accuracy is 1/20 of grating period
  • M23 flange socket or attached cable
  • Permissible axial motion of measured shaft is ±1.5mm
