- Model Replacement Recommendations
- Function-Prioritized Replacement: Select E6B2-CWZ1X 1000P/R
(Order code: E6B2-CWZ1X 1000P/R 0.5M/1M/2M)
Fully matches line driver output and 1000 P/R resolution
Suitable for most industrial applications requiring position/speed feedback
Note: Outer diameter φ40 mm (smaller than original), solid shaft (coupling required)
- Hollow Shaft Mounting-Prioritized Replacement: Select E6H-CWZ1X 1000P/R
(Order code: E6H-CWZ1X 1000P/R 0.5M/1M)
Hollow shaft design, no coupling needed, easier installation
Line driver output supports long-distance signal transmission (up to 100 m)
Note: Outer diameter φ40 mm (smaller than original), bore size 8 mm (adaptation may be needed)
- Harsh Environment Replacement: Select E6C3-CWZ6C 1000P/R
(Order code: E6C3-CWZ6C 1000P/R 2M)
IP65f protection, oiland water-resistant, ideal for harsh industrial environments
Push-pull output with high compatibility, can replace line driver
Note: Outer diameter φ50 mm (smaller than original), solid shaft
- Important Notes
- Omron does not offer an identical φ80 mm outer diameter hollow shaft encoder; the closest alternatives are φ40 mm and φ50 mm series.
- Line driver output (Z5) corresponds to the “1X” suffix (E6B2-CWZ1X) or “3X” suffix (E6H-CWZ3X) in Omron models.
- Hollow shaft bore sizes may differ (original: typically 10 mm/15 mm; Omron E6H-C series: 8 mm)-verify mounting compatibility.
- Supply voltage must match: line driver output typically requires 5 V DC, while push-pull output supports 12–24 V DC.
- Selection Guide
Choose the most suitable replacement based on your application:
Standard industrial use: E6B2-CWZ1X 1000P/R (function-matched, cost-effective)
Direct mounting on servo motors: E6H-CWZ1X 1000P/R (hollow shaft, convenient installation)
Wet, dusty or oily environments: E6C3-CWZ6C 1000P/R (IP65f protection, high durability)
