Omron E6B2-CWZ6C Incremental Rotary Encoder, 300 P/R, 2 m Cable

Compact 40 mm incremental encoder for general motion feedback

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.
