HEIDENHAIN RON 225 / 275 / 285 / 287 Angle Encoders | Quote

Ask AMI about a HEIDENHAIN RON 200 series angle encoder for repair, replacement, or sourcing. Quote and configuration on request; availability and the exact replacement path must be confirmed for your application.

Models covered

  • RON 225: incremental, 9,000-line measuring standard, TTL output with 2-fold interpolation, 18,000 output signals per revolution, one reference mark, ±5 arcsecond system accuracy.
  • RON 275: incremental, 18,000-line measuring standard, TTL output with 5-fold or 10-fold interpolation (90,000 or 180,000 output signals per revolution), one reference mark, ±5 arcsecond system accuracy.
  • RON 285: incremental, 18,000-line measuring standard, 1 VPP output, one reference mark (distance-coded on RON 285 C), ±5 arcsecond system accuracy.
  • RON 287: incremental, 18,000-line measuring standard, 1 VPP output, one reference mark (distance-coded on RON 287 C), ±2.5 arcsecond system accuracy.

Exact ID pages

The series uses an integrated stator coupling and a 20 mm hollow through shaft. Interface, reference mark, interpolation, connection, and mechanical fit must be matched to the installed encoder. Send the full part number or ID, a nameplate photo, and your application details when requesting a quote.
