Spec-by-Spec Comparison

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

Same 17-bit absolute resolution 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 17-bit absolute inductive rotary encoder. The comparison column reflects the typical specification of a premium imported optical absolute encoder in the same resolution class (e.g. Tamagawa or Heidenhain 17-bit series).

Specification	RM10 — Luoyun (inductive)	Imported optical (17-bit class)
Measuring principle	Inductive — PCB coils + ASIC	Optical — glass code disc + light source
Resolution	17-bit absolute (131,072)	17-bit absolute
Rotary accuracy	0.001°	0.001° class
Ingress protection	IP67	Typically IP40–IP65
Temperature range	-40 to +85 °C	Often -20 to +85 °C or narrower
Oil, dust, condensation	No glass disc — unaffected	Glass disc contamination = failure
Shock & vibration	Simple structure, robust	Optics sensitive
Protocols	BISS-C / SSI / RS485 (Tamagawa-compatible)	Model-dependent
Per-unit test data	Yes — every unit ships with its report	Not always
Customization	Shaft, cable, connector, protocol per drawing	Usually fixed catalog

Total Cost

The cost story is structural, not a discount

Factory direct

You deal with the manufacturer, not a trading company — no import premium, no multi-layer distribution margin.

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.
