Product Description:

The H220001104225 rotary encoder is manufactured by Danaher and belongs to the Dynapar Encoders series. Designed for mounting on motor or machine shafts, the unit detects angular displacement and issues a periodic electrical pulse to support basic speed, index, or homing functions in automated equipment. By furnishing a clean logic-level signal, it allows motion controllers to track shaft movement without requiring more complex absolute feedback hardware. Because the model uses a compact sensing head, it fits inside existing housings where real-time feedback is required.

Electrical and dynamic performance centers on a frequency response of at least 100 kHz, which lets counting electronics register high rotational rates without signal loss. The optical disk can turn safely at speeds up to 10,000 rpm, and the drive circuitry supplies up to 40 mA through its push-pull output stage, allowing the encoder to drive long cable runs. Protection against dust and coolant spray is provided by a NEMA 12/IP54 enclosure, while a flange-mount interface secures the housing directly to bulkheads or motor end bells. Low rotor inertia of 3.0 × 10⁻⁴ oz-in-s² minimizes the load on the host motor. Starting torque remains below 2.0 oz-in to prevent excessive breakaway friction. A single track produces 1 PPR, providing a clear index reference that is easy for connected controls to decode.

A 1.25-inch male pilot centers the case for accurate mechanical alignment. Shaft coupling uses a 3/8-inch solid stainless steel shaft rated for continuous motion in either direction through bidirectional sensing. A contact lip seal is fitted at the shaft entrance to prevent oil or debris from entering the housing. The assembly connects through a 10-pin side connector, which provides an accessible connection point for the signal cable. Overall mass remains below 10 oz, allowing the encoder to mount on small actuators without placing excessive stress on support brackets.
