Heidenhain
Heidenhain rotary encoders — incremental and absolute
Heidenhain encoder part numbers (EQN 1325, ECN 1313, ERN 1387, EQI 1325) are what machine-tool builders stamp on the axis. We quote those exact rotary encoders from U.S. channels — including 2048-line incremental and multi-turn absolute models.
Heidenhain encoder types we source
Absolute rotary (EQN / ECN / EQI)
Single-turn and multi-turn absolute encoders that keep position after power loss.
Incremental rotary (ERN)
ERN 1387 and similar 2048 P/R incremental encoders for servo feedback.
Linear (on request)
Exposed and sealed linear scales quoted from the nameplate when the rotary unit is not the spare you need.
Why Heidenhain encoders are bought in the USA
- The CNC axis encoder is a Heidenhain EQN/ERN number with no local distributor stock
- Line count, coupling, and output (EnDat vs incremental) must match the drive
- Obsolete 1325-series units still appear in North American inventory
