Omron E6B2-CWZ6C Rotary Encoder
Omron E6B2-CWZ6C is a 40 mm incremental rotary encoder with A, B and Z phases from NPN open-collector outputs (30 V max, 35 mA sink), ordered at 10–2000 P/R (this record: 1000 P/R). It runs on 5–24 VDC at 80 mA max, responds to 100 kHz and 6000 r/min, and has a Ø6 mm shaft (30 N radial / 20 N thrust), IP50, −10 to 70 °C, 3 × M3 on Ø30 mm and 0.5 m pre-wired cable.

| Pad / pin | Position | Role | Notes |
|---|---|---|---|
| Power supply (+Vcc) | output | Brown wire — Power supply (+Vcc) | |
| Output phase A | output | Black wire — Output phase A | |
| Output phase B | output | White wire — Output phase B | |
| Output phase Z | output | Orange wire — Output phase Z | |
| 0 V (common) | output | Blue wire — 0 V (common) |
CPR counts both edges of both channels on the sensed shaft; on a gearmotor multiply by the gear ratio for the output shaft.
Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
