Technical Overview

The Omron E6B2-CWZ6C 100P/R 2M is a compact, industrial-grade incremental rotary encoder featuring a 40mm external diameter casing and a robust 6mm solid stainless steel shaft. Providing a reliable resolution of 100 pulses per revolution (PPR) through optical sensing technology, it outputs A, B, and Z phase signals via an NPN open-collector interface. Engineered to support high-speed operations up to 6000 RPM with a maximum response frequency of 100 kHz, this encoder is ideal for precise position, angle, and speed tracking. Operating on a versatile 5 to 24 VDC power supply, the unit comes pre-wired with a 2-meter flying lead cable and features an IP50 environmental rating, making it perfectly suited for standard indoor automation and motion control applications.

Key Features

Industrial Applications

1. Conveyor Belt Speed Monitoring in Packaging Lines

Integrated into the drive roller of an automated conveyor to monitor the linear belt speed, allowing programmable logic controllers (PLCs) to precisely synchronize downstream stations.

Problem Solved

Prevents product misalignment and packaging errors by ensuring exact timing between the material handling system and secondary processing machinery like labelers and fillers.

2. Material Length Measurement for Automated Cutting

Coupled with a measuring wheel on roll-to-roll machinery (such as paper, textiles, or metal foil dispensers), the encoder tracks the exact length of material fed into the system before triggering a cutting blade.

Problem Solved

Eliminates inaccurate manual measurements and material waste in continuous feed applications by using reliable phase pulse counting for automated cut-to-length precision.

3. Motor Position Verification in Light-Duty Gantries

Mounted to the tail shaft of an asynchronous or stepper motor in a pick-and-place gantry, the encoder acts to verify actual rotational steps and confirm successful tool positioning to the central controller.

Problem Solved

Provides highly responsive, cost-effective closed-loop feedback to instantly detect motor stalling, missed steps, or mechanical binding without the financial burden of absolute encoders.
