TAMAGAWA TS4600 Hollow Shaft Servo-Specific Encoders

The TS4600 series from Tamagawa Seiki is a high-performance hollow shaft absolute encoder designed for servo motors, suitable for high-precision motion control scenarios. Its core advantages include compact structure, high resolution, strong anti-interference ability, and support for multiple industrial communication protocols.

1. Product Overview

Type: Absolute rotary encoder (single turn/multi-turn optional)

Shaft type: hollow shaft (hollow structure, easy cable threading)

Resolution: High resolution (such as 17~23-bit single turn, multi-turn optional)

Output interface: Supports SSI, BiSS-C, incremental (A/B/Z), serial communication (such as Modbus)

Protection level: IP65 (dustproof, splashproof)

Mechanical design: lightweight metal housing, vibration resistance (suitable for high-speed operation of servo motors)

2. Core features

(1) Servo motor optimized design

Hollow shaft structure (typical aperture: Φ12mm, Φ14mm, etc.), directly installed on the motor shaft, saving space.

Low inertia design, suitable for high dynamic response (speed can reach 8000 RPM+).

(2) High precision and stability

Single-turn resolution is up to 23 bits (8,388,608 steps/turn), and multi-turn is achieved through mechanical gears or electronic counting.

Absolute encoding, position memory is maintained after power failure (multi-turn models do not require batteries).

(3) Flexible electrical interface

SSI (Synchronous Serial Interface): Suitable for PLC and CNC systems.

BiSS-C (open source protocol): Supports high-speed real-time communication.

Incremental output (A/B/Z): Compatible with traditional servo drives.

(4) Environmental adaptability

Working temperature: -10°C ~ +70°C

Anti-electromagnetic interference (EMC) design, suitable for industrial sites.

3. Typical applications

Servo motor: used for high-precision position feedback of robot joints and automation equipment.

CNC machine tools: spindle positioning, feed axis control.

Semiconductor equipment: wafer handling, precision alignment system.

Logistics automation: steering control of AGV (automatic guided vehicle).

4. Model and selection guide
