Product Description:

The HA62525400021 is an incremental rotary encoder manufactured by Danaher as part of the Dynapar Encoders series. The device translates mechanical rotation into electrical pulse trains that allow drives, PLCs, and motion controllers to monitor speed, direction, and accumulated position in automated equipment such as conveyors, unwinders, and cut-to-length stations. Its optical sensing system and sealed housing make it suitable for general industrial feedback duties where precise, repeatable shaft information is required.

Measurement resolution is 2540 PPR, giving controllers more than two thousand pulses per revolution for tight velocity and position control. The encoder electronics operate from a single 5 VDC logic rail and use a totem-pole output driver, enabling active high and low outputs without additional line receivers. The electronics support signal frequencies of at least 100 kHz, while the mechanical speed limit of 5,000 rpm accommodates most medium-speed drives. During operation at full speed, the circuitry draws no more than 80 mA, minimizing the load on auxiliary power supplies and leaving capacity available for other control devices. This power demand also allows the encoder to operate from common regulated supplies used for industrial sensors and feedback equipment.

The aluminum housing has a protection rating of NEMA 4 / IP66, sealing the optics against airborne contaminants and directed washdown streams. Electrical connection is provided through a side-mounted 7-pin MS3106A-16S-1S circular connector, which secures the cable connection against vibration and accidental disconnection. A precision solid shaft with a 3/8-inch diameter couples to flexible or rigid hubs used in industrial drive systems. Its low inertia of 3.0 × 10⁻⁴ oz-in-s² and starting torque of no more than 2.5 oz-in help keep acceleration demands modest. The flange-mounted base supports accurate alignment with the driven shaft and provides a stable attachment point for the encoder housing.
