Showing the single result
In high-precision industrial automation and computer numerical control (CNC) manufacturing, motion accuracy is paramount. Tamagawa Seiki has long been recognized as a global leader in spatial and angular position sensing technology. From heavy-duty metalworking lathes and 5-axis machining centers to high-speed robotics, Tamagawa rotary encoders and OIH/FA-Coder series resolvers provide the critical feedback necessary for exact axis positioning, precise velocity control, and smooth spindle rotation.
When a rotary encoder fails on your production line, the consequences are immediate: unexpected machine downtime, lost position memory, axis tracking errors, and costly delays in manufacturing schedules. Finding an authentic, high-performance replacement component quickly is essential to keeping your plant running efficiently. At 24cnc.com, we carry an extensive inventory of new, original, and fully tested surplus Tamagawa replacement encoders, optical coders, and brushless resolvers to restore your CNC machinery to peak OEM operational standards.
Whether you require an absolute encoder for high-end servo systems or a rugged incremental encoder for heavy industrial duty, explore our specialized inventory below or consult with our technical team to find the exact part number for your machine.

Tamagawa Encoder & Resolver Selection Guide: Finding the Right Part Number
Tamagawa manufactures position sensors under several key technological categories, serving as both standard components and specialized OEM solutions integrated into motor brands like Mitsubishi, Yaskawa, Sanyo Denki, and custom servo setups. Selecting the correct replacement unit involves identifying several critical parameters:
1. Incremental Encoders vs. Absolute Encoders
- Incremental Encoders (e.g., OIH series): Output pulse streams relative to motion starting points. If you are replacing an incremental feedback device, pay close attention to the Pulses Per Revolution (PPR), output phase channels (A, B, Z), and output circuit types (Line Driver, Totem Pole, or Open Collector). Explore our full range of incremental rotary encoders for detailed specifications.
- Absolute Encoders (e.g., TS5600 / TS5700 series): Retain exact multi-turn and single-turn position data even after power loss. When selecting an absolute encoder, match the resolution (e.g., 17-bit, 23-bit) and communication protocol (Serial RS-485, EnDat, or proprietary bus systems).
2. Tamagawa Brushless Resolvers (Singlsyn & Smartsyn)
Tamagawa resolvers (such as the TS2600 series) utilize electromagnetic induction rather than optical glass discs. Known for extreme resistance to high temperatures, heavy vibration, oil splash, and dust, these units are frequently installed inside heavy-duty servo motors. Ensure that operating excitation voltage, transformation ratio, and mounting flange dimensions match your target specification exactly.
3. Wiring, Connectors, and Interfacing
Even if two encoder models share internal electrical specs, variations in cable length, tail leads, or connector shell types can affect installation speed. We recommend pairing your order with high-flex encoder cables and heavy-duty engine-side connectors to guarantee seamless connection back to your main CNC control system or drive modules.
