The Dynapar G0539431 (AX71/1212EK.72DPA-K0) is an incremental optical rotary encoder from the H20 series, delivering two-channel quadrature output with optional index (Z) channel for precise shaft position and speed feedback. It supports resolutions from 1 to 2540 PPR with accuracy of ±7.5 arc-min for <1024 PPR (metal disk) or ±2.5 arc-min for ?1024 PPR (glass disk), powered by 5-26 VDC at 80 mA max, and compatible with open collector, push-pull, or differential line driver outputs up to 100 mA. Mechanical specifications include shaft sizes of 10 mm, 1/4", or 3/8", radial/axial shaft loading up to 80 lbs (?1024 PPR), max shaft speeds of 10,000 RPM (?1024 PPR), aluminum housing with stainless steel shaft, and environmental ratings for 0 to +70°C operation, 50G shock, 20G vibration, and 98% humidity (non-condensing). Typical applications include factory automation, motor feedback, and conveyor speed measurement with side or end-exit cable mounting options.
