Product Description:
The HS35R10248447 is a hollow-shaft incremental encoder manufactured by Danaher within the Dynapar Encoders series. It converts rotary motion into electrical pulse trains that allow variable-frequency drives, PLC high-speed counters, and distributed control systems to measure shaft speed and position in automated equipment such as conveyors, winders, and servomotor assemblies. Because the sensing disk is installed around the motor shaft instead of requiring a separate projecting shaft, the encoder has a compact installation profile and does not require a flexible coupling.
The encoder outputs 1024 PPR, so one revolution produces 1,024 quadrature pulses that a controller can scale for moderate-precision feedback. A through-bore of 5/8 in fits standard 0.625-inch shafts and supports accurate alignment with the rotating assembly. The unit tolerates rotational speeds of up to 3600 rpm in machinery that operates within the permitted mechanical load limits. Its sensing electronics respond to pulse frequencies as high as 100 kHz, supporting rapid acceleration profiles without data loss. The die-cast housing has a sealing rating of NEMA 4 / IP66, protecting the internal optics against dust ingress and washdown sprays. Maximum supply current is 100 mA, allowing the encoder to operate from compatible industrial control circuits without imposing a heavy electrical load. Starting torque is limited to 5.0 oz-in, while running torque remains below 4.5 oz-in to minimize the added load on the drive train.
The encoder supports an axial bearing load of up to 30 lb, helping protect the hub from thrust produced by connected machinery. Its radial bearing load limit is 40 lb, which accommodates forces associated with belt tension and minor shaft misalignment. Continuous operation from -40 °C to +70 °C permits use in unheated outdoor enclosures and warm motor compartments. The rotor has an inertia of 7.9 × 10⁻⁴ oz-in-s², reducing its effect on the dynamic response of lightweight servo axes. A maximum mass of 16 oz also limits the overhung load applied to the supporting motor or machine shaft.
