E6A2-CWZ3C200P/R 0.5M - Omron Electronics

E6A2 E6A2

Miniature Rotary Encoder for

Positioning in Space-Confined Areas

■Wide variety of supply voltages and output

forms to match input devices

■Models with zero index function ideal

for positioning applications

■High resolution models (300 or 360 pulses

per revolution) substantially improve

measuring accuracy

■High response frequency and noise

immunity make encoders ideal for

factory automation applications

Incremental Rotary Encoder E6A2

Ordering Information

When ordering, add the resolution (pulses per revolution) between the part number and cable length.

For example, E6A2-CWZ3E

200

P/R 0.5M.
