Product Description:

The HS35R10247172 is an incremental hollow-shaft encoder produced by Danaher within the Dynapar Encoders series. It attaches to a rotating shaft and converts angular movement into square-wave output pulses. These signals allow motion controllers to monitor speed, direction, and position in industrial automation cells.

This model delivers a resolution of 1024 PPR, enabling fine velocity measurement at moderate shaft diameters. Its electronics support a frequency response of at least 100 kHz, so pulse trains remain clean even at high rotational rates. Mechanical rotation is permitted up to a maximum of 3600 RPM, matching common motor and gearbox speeds. An enclosure rating of IP66 seals the sensing head against dust and direct water jets. Input circuitry draws no more than 100 mA, limiting the load placed on supply rails. Quadrature phasing is specified at 90° ±22.5°, and signal symmetry remains within 180° ±18°, keeping the duty cycle and phase offset within typical controller tolerances. Running torque does not exceed 4.5 oz-in, so frictional losses to the host machine remain minimal. The encoder withstands shocks of 50 G for 11 ms and continues to operate through 20 G of vibration, making it suitable for installations on stamping presses or mobile equipment.

An axial load capacity of up to 30 lb and a radial load capacity of up to 40 lb allow the encoder to tolerate moderate belt tension or misalignment forces without bearing damage. Startup drag is limited to 5.0 oz-in, ensuring low breakaway torque during machine startup. The unit tolerates ambient relative humidity of up to 98% without internal condensation when mounting guidelines are followed. Its mass is limited to 16 oz, allowing installation on lightweight motor end bells without requiring substantial additional support.
