Customized DC-DC Converters Explore DC-DC ConvertersHigh-reliability, ultra-protected industrial incremental bearing rotary encoder. Designed as an exact professional drop-in interchange for the standard legacy Tamagawa OIH48 series, introducing optimized structural profiles, elevated immunity against line distortions, and perfect mechanical sizing alignment.
A premium thinned-down 48mm hollow shaft optical rotary encoder with integrated 6-channel feedback (A/B/Z and U/V/W commutation tracks). Engineered for direct 1:1 Tamagawa OIH48 compatibility, saving critical axial depth (32.8mm thickness) while delivering excellent electromagnetic immunity.
Well Protected: Advanced rugged sealing protects components from ambient dust, condensation, and dynamic temperature variations.
High Frequency Response: Fast optical sensing loops prevent any positioning lag at maximum frequencies.
High Reliability Components: Rigorous manufacturing design checks ensure zero performance decay during long industrial lifetimes in intense gantry or CNC fields.
Resolution range: Customizable pulse counts from 1000 up to 5000 CPR limit (Standard: 1024 CPR).
Differential outputs: Complete RS-422 standard Line Driver signals (AM26LS31 chip technology).
Count Frequency: High frequency response threshold up to 500 kHz limit tracking.
Working Temperature: Fully rated and qualified from -20 °C to +105 °C operating limits.
Voltage Input: Single 5V DC Supply (±5% tolerance).
Below is the dynamic high-fidelity dimensional drawing representing the physical boundaries of the EPOCH UZ4809 Compact Hollow Shaft Encoder series. Installation checks are highly recommended on the motor end axis to confirm direct replacement alignment:

Review our standard mechanical phase timing waveform and alignment equations mapped below. These represent the stable digital signal outputs required for seamless servo driver control feedback:
[WAVEFORMS] [Waveform Phase Diagram Omitted for Compatibility]
Default Timing Phase Sequence: Standard digital quadrature wave outputs. Phase A leads Phase B during CW rotation of the sleeve (viewed from sleeve attachment end). Active duty cycle ratio limits: 50% ± 10%. Signal Phase Z zero-index benchmark is aligned at active center (1T signal width period). Rotational Direction Phase: Signal Phase A leads Phase B when rotating counter-clockwise (CCW) as viewed from the encoder shaft sleeve mounting end.
Quadrature Cycle Width Tolerances: Square wave timing pulse widths X1, X2 = 0.25T ± 0.1T, where cycle period T = 360 degrees ÷ N (with N as the target line pulse count).
Index Pulse Width: High-precision Reference Phase Z has a standard width of 1T ± 0.5T, perfectly aligned and centered over active state transitions.
