Product Overview

The Omron E6B2-CWZ6C is a 40 mm-body incremental rotary encoder in the long-running E6B2 family. The "CWZ6C" suffix indicates an NPN open-collector output on phases A, B and Z (index), with a 5–24 VDC supply range — a combination that drops directly into the high-speed counter inputs of most Omron CP1H / CP1L / NJ / NX PLCs and into the encoder inputs of 1S and Accurax G5 servo drives.

The "300P/R" part of the ordering code sets the resolution to 300 pulses per revolution. At a 6,000 rpm maximum shaft speed, that gives a maximum output frequency of 30 kHz — well within the counting bandwidth of a standard PLC high-speed counter. The 2 m pre-wired cable variant ("2M" suffix) is the typical drop-in for cabinet-mounted applications where the encoder sits close to the drive or counter module.

The shaft is 6 mm diameter with a flat for set-screw coupling. The encoder body is rated IP50 — suitable for inside-cabinet or light-dust environments; for washdown or food-grade mounting, use the IP65-rated E6B2-CWZ6C variant with a sealed cable gland.

Common applications: conveyor speed feedback, indexing-table position, cut-to-length machines, simple length-measurement wheels. The E6B2 family is a workhorse — expect millions of revolutions of bearing life and predictable performance across temperature.

Key Features

  • 300 P/R resolution — 30 kHz output at max 6,000 rpm
  • NPN open-collector output, phases A, B, Z
  • 5–24 VDC supply range — works with 12 V and 24 V PLC inputs
  • 40 mm body, 6 mm shaft with flat
  • 2 m pre-wired cable (oil-resistant PVC)
  • Maximum shaft speed 6,000 rpm
  • IP50 protection (inside-cabinet / light-dust duty)
  • Operating temperature -10 °C to +70 °C
  • SKU: E6B2-CWZ6C 300P- R 2M
  • Series: E6B2-C
  • Voltage: 24 VDC

Best-Fit Applications

  • Conveyor belt speed feedback
  • Indexing-table position
  • Cut-to-length and metering-wheel measurement
  • Wire-drawing and winding-line length feedback
  • General motion feedback into PLC high-speed counters

Buying Checklist

  • Verify the P/R code (300 / 360 / 500 / 600 / 1,000 / 2,000) matches what your counter is configured for
  • Check the output type code — CWZ6C is NPN open-collector, CWZ6E is PNP
  • For PNP or line-driver output, use the matching CWZ6E or CWZ5G variant
  • For washdown or outdoor mounting, use the IP65-sealed variant instead of this IP50 unit
  • Confirm the cable length is right for the run — 2 m is the short-drop version; longer cables are available in the same family

FAQ for E6B2-CWZ6C 300P- R 2M

What does the "CWZ6C" suffix mean?
C = complementary output, W = 5–24 VDC supply, Z6 = A/B/Z phases, C = NPN open-collector. The complementary outputs (A and Ā) let you sink current in both directions, which gives better noise immunity than a single-ended output.
Can I use this with an NPN-input PLC?
Yes — that is exactly the application. The open-collector transistor pulls the PLC's input low on each pulse. For a PNP-input PLC, use the CWZ6E (PNP) variant instead.
Is 300 P/R enough resolution?
For a conveyor running at, say, 60 m/min with a 200 mm measuring wheel, 300 P/R gives ≈ 3.3 mm per pulse — fine for cut-to-length packaging but too coarse for precision positioning. For higher resolution, use the 1,000 P/R or 2,000 P/R variants in the same E6B2 family.
