Product Description:

The HA62520000131 is an incremental rotary encoder produced by Danaher as part of the Dynapar Encoders series. It converts shaft rotation into digital pulses for motion controllers, drives, or PLC high-speed counters, supplying position and velocity data that support closed-loop regulation in conveyors, packaging machines, and general automation cells. The glass code disc is coupled to the shaft and provides accurate pulse generation as the shaft rotates.

This model provides a resolution of 2000 PPR, so one full revolution is subdivided into two thousand equally spaced counts for fine positional indexing. Signal bandwidth is supported by a minimum frequency response of 100 kHz, allowing the electronics to process pulse rates generated at high rotational speeds without losing edges. The shaft may spin at up to 5000 rpm, which is the maximum operating speed for maintaining accurate tracking. The encoder has a sealing rating of NEMA 4 / IP66, protecting the aluminum housing against dust, directed water, and washdown spray in factory settings. The sensing head is mounted on a stainless-steel shaft with a diameter of 3/8 in, matching common coupling and bearing hardware used in fractional-horsepower drive trains.

The shaft can withstand an axial force of 40 lb and a radial force of 35 lb without degrading bearing life, enabling direct coupling to timing pulleys or light gear trains. Startup friction is low, and the assembly requires only 2.5 oz-in of torque to initiate rotation, reducing the drive motor load during machine startup. A moment of inertia of 3.0 × 10⁻⁴ oz-in-s² minimizes speed lag during rapid indexing. The encoder has an overall mass of 1.5 lb, so it adds little weight when mounted on small-frame motors or lead-screw ends. Its low rotational resistance also reduces the mechanical burden placed on compact drive systems during frequent starts and stops.
