WHERE RM ENCODERS DELIVER

Built for the industries that never stop moving

From humanoid robot joints to maglev tracks, our encoders deliver precision where optics fail and magnets drift.

Humanoid robot joint with integrated encoder

RM10

Humanoid robots

A single humanoid uses about 54 encoders. Our lightweight, EMI-immune inductive units survive continuous articulation in dense joint modules.

RM10

Industrial robots

Joint position feedback for six-axis arms, SCARA and delta robots operating at high speed with high repeatability.

Precision servo motor with encoder feedback

RM10

Servo motors & drives

Drop-in absolute feedback for servo systems using RS485 Tamagawa protocol, plus BISS-C for next-generation drives.

Precision linear motor stage with linear encoder

RM20

Linear motors & stages

0.03 µm linear accuracy for precision positioning stages and direct-drive linear motor systems.

Maglev train — long-travel linear motion

RM20

Maglev & long-travel systems

Infinite cascade range for maglev tracks and long-stroke handling lines — precision never degrades with length.

CNC machining center with encoder feedback

RM10

Machine tools

Spindles, rotary tables and tool changers running 24/7 in coolant, chips and vibration.

RM10

Smart water & flow meters

Magnetic-free rotation sensing for battery-powered meters, averaging under 10 µA system power.

RM10 · RM20

New energy equipment

Solar trackers, wind pitch drives and EV systems demanding −40 ~ +85 °C and outdoor-rated protection.

Draw-wire displacement sensor for sorters and conveyors

RM10 · RM20

Logistics & automation

Sorters, shuttles and conveyors that run around the clock with minimal maintenance windows.

Humanoid Robotics Spotlight

54 encoders per humanoid — and counting

Global humanoid shipments are projected to nearly double in 2026. Every joint needs absolute, magnetic-immune, lightweight position feedback. We build exactly that — and we partner with robot makers to scale from prototype to production.

Selection Guide

Choosing your protocol

Every RM encoder ships with one shared 8-pin terminal that supports all three protocols — decide at integration time, not at order time.

RS485 · Tamagawa BISS-C · CRC checked SSI · simple & proven

The industry standard for servo motor feedback, widely used in Japanese and Chinese servo ecosystems. Choose RS485 when replacing Tamagawa-compatible encoders or integrating with existing RS485 drives.

A high-speed bidirectional protocol with CRC safety checking. Ideal for high-dynamic robot and servo applications where real-time data integrity matters.

The simple, proven synchronous serial interface. Best for general industrial machines where cost and simplicity matter more than bandwidth.
