Product Overview

The Omron E6B2-CWZ6C 300P-R is a 40 mm incremental rotary encoder from the E6B2-C family, manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.

The encoder ships in a 40 mm-diameter metal housing with a 6 mm solid shaft. It delivers 300 pulses per revolution on A, B, and Z phase outputs through an NPN open-collector driver rated 35 mA sink / 30 VDC applied max / 0.4 V residual max. A and B phases lead by 90 +/- 45 degrees.

Supply is 5 to 24 VDC at 70 mA max. Maximum response frequency is 100 kHz; maximum rotation 6000 RPM. Starting torque 0.98 mN.m max; shaft loads 30 N radial / 20 N thrust. Operating range -10 to +70 C. The 2 m pre-wired PVC cable carries the signal leads. IP50 IEC / IP64 JEM. The 2000 PPR variant in the same body is E6B2-CWZ6C 2000P-R.

Key Features

  • E6B2-C-series 40 mm-diameter incremental rotary encoder with 6 mm solid shaft and 300 P/R resolution
  • NPN open-collector output on A, B, and Z phases, 90 +/- 45 deg quadrature, 35 mA sink / 30 VDC max applied
  • 5 to 24 VDC supply at 70 mA max, 100 kHz max response, 6000 RPM max rotation, 0.98 mN.m starting torque
  • 30 N radial / 20 N thrust shaft load, IP50 IEC / IP64 JEM, pre-wired 2 m PVC cable, -10 to +70 C operating
  • SKU: E6B2-CWZ6C 300P-R
  • Series: Omron E6B2-C 40 mm incremental rotary encoder
  • Voltage: 5 TO 24 VDC

Best-Fit Applications

  • Conveyor speed feedback on a packaging line where 300 PPR with quadrature gives 1200 counts/rev for accurate length measurement
  • Motor shaft tachometer on a 1450 RPM induction drive where the 6000 RPM headroom and 100 kHz response cover the full ramp profile
  • Cut-to-length register on a textile web where the Z pulse from the encoder re-zeros the cut at every fabric splice

Buying Checklist

  • Pick the E6B2-CWZ6C 300P-R for a 40 mm NPN incremental encoder with 300 PPR on a 5-24 VDC supply.
  • Pick the E6B2-CWZ6C 2000P-R instead when the same body needs 2000 PPR for higher position resolution.
  • Pick the E6B2-CWZ1X instead when the line-driver output (RS-422A equivalent) is required for long cables.

FAQ for E6B2-CWZ6C 300P-R

What is the resolution of E6B2-CWZ6C 300P-R?
300 pulses per revolution (PPR). With quadrature decoding on A and B, a counter module reads 1200 counts per revolution. The 2 m cable length is the standard pre-wired variant.
Does E6B2-CWZ6C 300P-R need pull-up resistors?
Yes. The NPN open-collector output pulls the line low; an external pull-up to the PLC input voltage is required. Many Omron CP1L and CJ2 counter inputs have internal pull-ups so wiring is just the encoder leads.
Can E6B2-CWZ6C 300P-R run on a 5 V supply?
Yes. The supply range is 5 to 24 VDC with a -5% to +15% tolerance. At 5 V the residual voltage rises so confirm the counter-input threshold on the receiving PLC.
What is the difference between E6B2-CWZ6C and E6B2-CWZ1X?
CWZ6C is NPN open-collector, 5-24 VDC. CWZ1X is RS-422A line-driver, 5 VDC, for long cables and high noise. Both share the same 40 mm body and 6 mm shaft.
