Product Description:

The HS35R0100D310 is a hollow-shaft incremental encoder produced by Danaher within the Dynapar Encoders series. The unit mounts directly on a motor or gearbox shaft and generates square-wave pulses that a drive or PLC reads as speed and position information, enabling closed-loop regulation of conveyors, winders, and servo axes. A clamp collar secures the encoder to the shaft while an anti-rotation bracket holds the housing stationary, allowing the device to deliver motion feedback without adding appreciable radial stress to the driven element.

The mechanical interface has a bore diameter of 20 mm, which accommodates common metric shafts, while a bore tolerance of +0.0003/+0.0005 in supports accurate installation. The optical disc provides a resolution of 100 PPR, so one revolution produces 100 pulses that control electronics can multiply through quadrature decoding. Signal fidelity is maintained with a minimum frequency response of 100 kHz, permitting reliable counting near the maximum mechanical speed of 3600 rpm. Internal friction remains low because the maximum running torque is 4.5 oz-in, reducing heat and power draw. Starting torque stays below 5.0 oz-in, the moment of inertia is 25.6 × 10⁻⁴ oz-in-s², and the overall mass does not exceed 16 oz. These characteristics help preserve responsive servo dynamics while limiting the load placed on the host shaft.

The housing tolerates an axial load of 30 lb and a radial load of 40 lb, making the encoder suitable for belt-tensioned or gear-coupled arrangements. It withstands shocks of 50 G for 11 ms without losing accuracy, helping it maintain dependable feedback when machinery experiences sudden impacts or abrupt changes in motion. Its sealed NEMA 4/IP66 enclosure blocks dust and high-pressure water, allowing installation in washdown areas or outdoor environments where moisture and airborne contaminants are present.
