Core Technology

Inductive sensing. The next generation of encoders.

Our AFEA1001 IC drives planar PCB coils and reads sub-micron position changes through eddy-current coupling — no optics, no glass scale, no magnets to demagnetize.

Immune to dust, oil, moisture and condensation — nothing to clean
No LED aging, no glass disk breakage, no mechanical wear
Unaffected by external magnetic fields — ideal next to motors
Wide −40 to +85 °C operation, far beyond typical optical encoders

FAQ

Common questions from buyers and engineers

For RS485 Tamagawa-protocol systems and SSI setups, yes — the RM10 uses the same electrical interface, so motor and drive makers can qualify it as a second source without redesigning their controller. BISS-C versions are available for high-dynamic applications.

We start with samples (1–10 pcs) for qualification. Pilot orders begin from 100 pcs, and volume pricing applies from 1,000 pcs per year. For OEM partnerships we offer scheduled delivery and consignment options.

Yes. Because we control the ASIC and the assembly line, we can adapt protocols, interfaces, dimensions, mounting and even the chip functionality itself. Typical customizations take 4–8 weeks to sample.

Every encoder is 100% factory tested. The series passes ±12 kV ESD (IEC 61000-4-2), 95% RH / 96-hour high-temperature humidity, 10 Hz–2 kHz vibration on all axes, and 980 m/s² mechanical shock. ISO 9001 quality system, 12-month warranty.

Yes — we are actively building a global distributor network in Europe, Southeast Asia, India and Latin America with exclusive territory agreements, technical training and marketing support.
