The EIL 580 Series Standard Duty Incremental Encoder is a compact optical rotary encoder built for general industrial speed and position feedback where reliable performance matters more than extreme-environment survival. It runs on a wide 4.75–30 VDC supply range, delivers resolutions up to 5000 increments per turn, and is available with either TTL or HTL electrical output to match common controller interfaces. With an IP65 protection standard (IP67 with the optional shaft seal) and a die-cast aluminium housing, it's designed to hold up to everyday factory-floor conditions, dust, moderate vibration, and routine handling, at a price point suited to volume deployment across machines rather than a handful of critical drives.

It's available from 100 up to 5000 increments per revolution, covering both basic speed-sensing needs and more precise positioning tasks within the same product family.
The clamping flange version uses a 10×20 mm solid shaft with edge, while the synchro flange version uses a 6×10 mm solid shaft with edge, the choice depends on which shaft mounting convention your existing drive or machine design uses.
Yes. TTL/RS422 output runs at up to 300 kHz output frequency, while HTL/push-pull output runs at up to 160 kHz — pick whichever matches your controller's input stage.
IP65 as standard (without a shaft seal), upgradeable to IP67 by fitting the optional shaft seal, suitable for dusty or occasionally damp industrial environments.
-40°C to +85°C, with resistance to up to 90% relative humidity (non-condensing), covering most indoor and semi-outdoor industrial installations.
Yes. It includes reverse polarity protection as standard, and both TTL and HTL outputs are short-circuit proof (HTL indefinitely; TTL for up to 1 second on a single signal).
