Incremental rotary encoder EI22A-E9

magnetic12-bitshaft-mounted

Product
EI22A-E9 is an incremental magnetic encoder in a compact Φ22 mm housing. It offers bushing (bore) mounting and PCB solder-pad connections. Resolutions are available up to 4096 PPR. Push-pull, TTL-compatible output and 3.3–5V supply make it suitable for motor feedback, speed and position sensing in industrial automation.
