The Omron E6C3-CWZ5GH 1000P/R 1M serves as the primary E6C3 Rotary Encoder utilized to execute high-resolution rotational position and speed measurement across motion control platforms. Operating via quadrature pulse output generation at 1,000 pulses per revolution, it transmits Phase A, Phase B, and Phase Z index signals directly to high-speed counter modules and drive controllers over a 1 m integrated cable interface.

Model Designation and Pulse Resolution Architecture

• E6C3: Rugged 50-mm-diameter outer housing encoder platform

• CWZ5GH: Complementary line driver/PNP/NPN output stage configuration with A, B, Z phase signals

• 1000P/R: 1,000 pulses per revolution optical disk resolution

Technical Parameters

Industrial PLC High-Speed Counter Integration

The encoder delivers deterministic pulse train feedback directly into high-speed counter (HSC) cards on PLC rack backplanes. Fast output transistor switching suppresses signal attenuation, enabling real-time velocity calculation and position tracking without losing edge synchronization during rapid shaft acceleration. Compatible with high-density I/O configurations, the output signal stage maintains stable voltage margins across varying power supply levels under continuous high-speed rotation.

Physical Installation and Wiring Standards

Shaft Alignment and Coupling Assembly

• Mount the encoder shaft to the drive shaft using a flexible coupling to accommodate angular and parallel misalignment.

• Do not apply excessive axial load exceeding 30 N or radial load exceeding 50 N directly to the encoder shaft during installation.

Cable Routing and Noise Suppression

• Route the 1 m encoder cable inside grounded metallic conduit separate from high-voltage AC motor lines.

• Connect the cable shield wire to a single-point protective earth (PE) terminal at the controller enclosure to avoid ground loops.

Frequently Asked Questions

• What supply voltage range is permissible for powering this rotary encoder model?

  The encoder accepts an input voltage range from 12 VDC -10% up to 24 VDC +15% with a maximum peak-to-peak ripple of 5%.

• How many output pulses are generated during one complete 360-degree rotation?

  The optical disc structure generates exactly 1,000 pulses per revolution for Phase A and Phase B quadrature outputs.

• Is hot-swapping the encoder cable permissible while the PLC system is powered on?

  No, hot-swapping is not supported; always isolate main DC power before disconnecting or reconnecting encoder signal wiring.

• How should the Phase Z output signal be utilized in motion control programs?

  Phase Z provides a single index pulse per full rotation, used primarily as a precise mechanical reference mark for homing sequences.

• What is the maximum operating ambient temperature limit for this unit?

  The encoder operates reliably within an ambient temperature range of -10 to 70 deg C without icing conditions.

• How does cable length extension affect signal integrity from the encoder output?

  Extending cable length increases conductor resistance and capacitive load, which may round pulse edges at maximum rotational speeds.

• Can this encoder withstand direct washing or immersion in liquid solutions?

  No, the unit is sealed against industrial oil and splash environments but must not be submerged in liquid solutions.

• What mechanism prevents pulse miscounts caused by electrical noise on signal lines?

  Utilizing twisted-pair shielded cables and enabling hardware input filters on the PLC high-speed counter suppresses transient noise.
