Koyo Electronics TRD-NH50-RZ Incremental Hollow Shaft Rotary Encoder (Made in Japan):
- Technical Specifications: Outer body diameter 50 mm, blind/through hollow shaft diameter Ø8mm / Ø10mm with leaf spring mounting bracket, incremental optical pulse generation (A, B, Z phases with inverted signals), output types: Totem Pole (Push-Pull) / Line Driver (RS-422), operating voltage 4.75-30V DC (wide supply range), maximum response frequency up to 200 kHz, maximum rotational speed 5,000 RPM, operating temperature -10°C to +70°C, IP50 industrial dust protection, Product of Koyo Electronics Industries Co., Ltd. (JTEKT Corporation) Japan.
- Direct Hollow Shaft Mounting Architecture: Clamps directly onto motor shafts without requiring shaft couplings, dramatically saving axial machine space and eliminating coupling runout.
- High-Speed 200kHz Frequency Response: Accurately tracks high-RPM spindle motors, servo drives, and robotic axes with zero missed pulse counts.
- Rugged Industrial Optical Disk Technology: High-precision etched glass/metal grating disk delivers ultra-reliable quadrature square-wave position feedback.
- Flexible Wide-Voltage Range (4.75-30V DC): Compatible with standard 5V TTL controller logic as well as 12V and 24V industrial PLC high-speed counter cards.
- Flexible Leaf Spring Torque Arm: Absorbs motor shaft radial/axial runout and vibration while keeping the encoder body precisely stationary.
- Applications: AC servo motors, CNC machine tool spindles, textile spinning machinery, automated conveyor sorting, and printing presses.
