φ40 mm Incremental Encoder for Industrial Feedback Loops
The Omron E6B2-CWZ6C is a 40 mm diameter incremental rotary encoder from the E6B2-C family, designed for reliable speed and position feedback on industrial automation equipment. It provides 600 pulses per revolution across three output phases (A, B, Z) with NPN open-collector outputs, and operates from a wide DC 5–24 V supply.
The quadrature A and B phases deliver direction-sensing and 4× resolution (2400 counts/rev) when decoded by an up/down counter, while the Z (index) pulse provides one marker per revolution for homing and origin positioning. Maximum response frequency is 100 kHz and maximum rotational speed is 6000 rpm, covering most conveyor, spindle, and servo-feedback applications.
Protection features include load short-circuit protection and reverse-polarity protection on the power supply. The pre-wired 0.5 m cable exits axially; longer 2 m variants are available in the same family for distributed-cabinet installations. For applications requiring line-driver outputs or higher noise immunity, see the E6C2-C or E6CP family.
Typical Applications
- Servo motor and stepper drive position feedback
- Conveyor speed monitoring and cut-to-length control
- CNC machine tool axis feedback
- Packaging machinery registration-mark timing
- Textile and printing equipment synchronisation
- Robotic axis position verification
- General industrial counting and rate measurement
Buying Checklist
- Verify PLC high-speed counter input type — NPN open-collector outputs require pull-up resistors or an NPN-compatible input card.
- For longer cable runs (>10 m) or noisy environments, specify the E6C2-C line-driver variant instead.
- Confirm shaft load ratings (30 N radial, 20 N axial) for your coupling selection.
- For 1000 / 1024 / 2000 P/R variants in the same family, order the E6B2-CWZ6C 1000P/R, E6B2-CWZ6C 1024P/R, etc.
- Add the E69-DF5 line-receiver if wiring to a differential-input motion controller.

Frequently Asked Questions
What cable length and connector options exist for the E6B2-CWZ6C?
Standard cable is 0.5 m pre-wired with axial exit. 2 m variants are available in the same family (suffix "2M"). For longer cable runs, use a shielded extension cable and keep wiring at least 200 mm away from VFD or power cables. Line-driver outputs (E6C2-C family) are recommended for cable runs over 10 m.
How do I wire the E6B2-CWZ6C to a PLC high-speed counter?
Brown to DC+ (5–24 V), blue to DC− (0 V), black to high-speed counter input A, white to high-speed counter input B, orange to input Z. Add pull-up resistors (2.2 kΩ typical) on A and B if your PLC requires them. Shield the cable and ground the shield at the controller end only.
Can this encoder be used for both speed and position feedback?
Yes. The A/B quadrature channels give direction and 4× resolution (2400 counts/rev at 600 P/R) when read by an up/down counter. The Z (index) channel provides one pulse per revolution for homing, origin reset, and slip-detection on conveyors.
What resolutions are available in the E6B2-C family?
The E6B2-CWZ6C family offers 13 resolution options from 100 to 2000 P/R: 100, 200, 300, 360, 400, 500, 600, 1000, 1024, 1200, 1500, 1800, and 2000 P/R. Select by SKU suffix — for example E6B2-CWZ6C 1000P/R for 1000 P/R or E6B2-CWZ6C 2000P/R for 2000 P/R.
