Product Description:

The HA6250500061018 is an incremental rotary encoder manufactured by Danaher for the Dynapar Encoders series. The unit attaches to a machine shaft and converts angular displacement into digital pulse trains so a drive or PLC can track position and speed within an automated axis. By turning mechanical rotation into electrical information, the encoder enables closed-loop feedback on conveyors, indexing tables, and similar motion platforms.

The glass disc inside the sensor contains a pattern that yields a native resolution of 500 PPR, giving controllers a balance between accuracy and data rate. A frequency response of at least 100 kHz allows the output channels to toggle quickly enough for high-speed machinery, while a maximum shaft velocity of 5,000 rpm keeps mechanical stresses within design limits. Each channel produces a square-wave signal, and the A-to-B relationship is maintained at 90° ±22.5° quadrature so direction can be resolved in real time. Pulse-width symmetry is maintained at 180° ±18°, reducing duty-cycle errors that could affect velocity calculations. The encoder uses flange mounting, which places the sensing elements concentrically with the drive train. Its optically clear glass disc minimizes thermal expansion and maintains dimensional stability at speed.

The housing is machined from aluminum to dissipate heat and shield the electronics, while the stainless-steel shaft resists corrosion during washdown maintenance. The enclosure is sealed to IP66, preventing dust and powerful water jets from reaching the code wheel. Startup friction stays low because the bearing system requires only 2.5 oz-in of starting torque. A rotor inertia of 3.0 × 10^-4 oz-in-s² keeps acceleration demands on the host motor low. Overall mass is limited to 1.5 lb, making the encoder suitable for installations where added shaft load must remain modest. A 3/8-inch shaft interface allows the encoder to couple directly to many fractional-horsepower motors without adapters.
