Product Description:

The HS35R10248177 is a hollow-shaft incremental encoder manufactured by Danaher within the Dynapar Encoders series. It installs over a driven shaft and delivers electrical pulse streams that controllers interpret for speed and position feedback, enabling closed-loop regulation of motors and material-handling axes in automated equipment. A clamping collar and anti-rotation tether secure the encoder without requiring additional couplings, maintaining a compact axial length on conveyors, presses, and winders.

This model provides a resolution of 1,024 PPR for detailed motion feedback during each mechanical revolution. The output electronics support frequencies of at least 100 kHz, allowing accurate measurements on high-speed actuators. Sealing conforms to NEMA 4/IP66, which blocks dust ingress and withstands directed washdown jets. The electronics draw up to 100 mA from the supply, keeping the load on the controller modest. Dual square-wave channels are phased at 90° ±22.5° for directional sensing, while channel symmetry is held to 180° ±18° to limit duty-cycle error. Transition edges rise or fall in less than 1 µs with a 1,000 pF load, supporting signal transmission over long cable runs.

Bearing life is rated for 80,000 hours at 3,600 rpm, supporting continuous operation on motors used in pump or fan drives. Running torque is limited to 4.5 oz-in, and starting torque peaks at 5.0 oz-in, minimizing the additional load placed on low-horsepower shafts. The hub accepts a 5/8-inch bore, and the shaft bore tolerance of +0.0003/+0.0005 inch provides a tight but serviceable fit. The encoder can withstand a radial load of 40 lb and an axial load of 30 lb without reducing its rated bearing life. Its maximum operating speed is 3,600 rpm, which accommodates many common induction-motor applications. The encoder weighs no more than 16 oz, reducing the mounting load on lightly supported shafts.
