One-Sentence Selection Guide

Allgemeine Ausrüstung, domestic PLC → choose CWZ6C (NPN)
Imported/European PLC, PNP required → choose CWZ5B
Lange Distanz, high interference, high speed → choose CWZ1X (line drive)
NPN and PNP are NOT directly interchangeable; may cause no counting or port damage

OMRON E6B2 Series Encoder – Accuracy Classification

The E6B2 is an incremental rotary encoder.

Its accuracy is independent of the output model (CWZ5B / CWZ6C / CWZ1X).

Output type only determines the signal circuit.

Accuracy is determined solely by resolution (pulses per revolution: P/R).

Resolution means how many pulses are output per revolution.

Higher pulse count = higher positioning/speed measurement accuracy.

This is the only accuracy grading standard for E6B2.

E6B2 Standard Resolution (Genauigkeit) Table

Auflösung (P/R)	Angle per Pulse	Genauigkeitsklasse	Typische Anwendungen
100	3.6°	Niedrig	Simple speed detection, rough counting
200	1.8°	Niedrig	Basic speed control, counting
360	1.0°	Mittel-Niedrig	General counting, simple positioning
500	0.72°	Medium	Allgemeine Automatisierung, Förderer
600	0.6°	Medium	Verpackungsmaschinen, small equipment positioning
1000	0.36°	Mittelhoch	Am häufigsten, Werkzeugmaschinen, servo systems
1024	≈0.3516°	Mittelhoch	Industrial positioning, length measurement
2000	0.18°	Hoch	Hochpräzise Positionierung, high-speed detection
2500	0.144°	Highest	Präzise Positionierung, CNC, Druckgeräte

All E6B2 encoders with the same resolution have identical electrical accuracy:

Angular accuracy: ±0.5°

Phase A/B difference: 90°±45°

Max response frequency: 100 kHz

Allowable speed range: 0–6000 r/min

Shaft radial play: ≤0.02 mm

Shaft axial play: ≤0.1 mm

Flange standard: φ50 mm, shaft φ6 mm

Schutzklasse: IP50

One-Sentence Summary
CWZ5B / CWZ6C / CWZ1X only change output circuit, nicht Genauigkeit.
Accuracy depends only on pulse count: 100–2500 P/R; higher number = more precise.
Most common industrial accuracy: 1000 P/R (0.36°)
