Spec-by-Spec Comparison

RM10 vs imported optical encoders —
the differences that matter in service

Same absolute feedback class as premium imported rotary encoders — with a measuring principle that survives what glass disc optics cannot.

Specification

Position feedback, compared honestly

RM10 is our absolute inductive rotary encoder. The comparison column reflects the typical specification of a premium imported optical absolute encoder in the same class (e.g. Tamagawa or Heidenhain absolute series).

Total Cost

The cost story is structural, not a discount

Because the AFEA1001 sensing SoC is our own silicon, there is no imported-chip markup in the BOM, and the sensor-plus-MCU single-chip design removes one external controller from your board. The same performance class typically costs 40–60% less than comparable imported encoders — a structural advantage, not a discount (based on our BOM structure; TCO analysis available on request).

Self-developed sensing IC

The AFEA1001 replaces an imported sensing chip and an external controller — no import markup, one less MCU in your BOM. High-volume customers can even customize at chip level.

Lower service cost

No glass disc means fewer field failures in oil, dust and vibration — lower warranty and service expense over the machine's life.

Documented quality

Every unit ships with its own test report and a 12-month warranty, so replacement decisions are data-backed, not faith-based.
