Product Description:

The HA62520480641 is an incremental rotary encoder produced by Danaher within the Dynapar Encoders series. It converts shaft rotation into electrical pulses so that motion controllers can track position and speed in automated machinery. By generating square-wave signals rather than analog feedback, the unit simplifies interface design for PLC-based systems that need deterministic count data.

This encoder delivers a resolution of 2048 PPR, giving control loops fine positional granularity for moderate-to-high-precision axes. A minimum frequency response of 100 kHz ensures that the output can follow rapid shaft changes without missed counts, while a mechanical limit of 5000 rpm caps usable speed before bearing wear or signal degradation becomes a concern. Signal lines are driven by a 7272 line driver in a balanced configuration, and each channel can source or sink up to 80 mA. These values indicate compatibility with long cable runs and differential receivers in electrically noisy cells. The topology is differential, so equal and opposite voltages appear on each pair, improving common-mode noise rejection when routed alongside inverter power conductors.

A 3/8-inch stainless steel shaft couples to the host machine through a flange mount and tolerates up to 35 lb of radial load plus 40 lb of axial thrust, so side-loaded belts or lightly preloaded gear wheels are supported. Environmental protection reaches NEMA 4 / IP66, keeping lubricated bearings isolated from coolant spray and airborne particulates. Connection is made through a side-mounted 7-pin MS plug, which permits disconnection without rewiring terminal blocks. No index channel is present, so absolute reference marks must be established externally after power-up. The 2.5 oz-in starting torque stays low enough to minimize additional drive loading during startup.
