Product Description:

The HS35R1024H04001 is an incremental rotary encoder produced by Danaher for the Dynapar Encoders series. Mounted on a rotating shaft, it converts mechanical motion into a train of digital pulses that a drive, PLC, or counter uses to determine speed, position, and direction within an automated line. By providing reliable feedback, the unit helps close control loops in packaging, material-handling, and general motion systems where consistent rotational data are required for coordinated machine actions.

This encoder has NEMA 4/IP66 enclosure protection, so sealed gaskets block dust and high-pressure water spray during washdown cycles. Electrical demand is limited to 100 mA, permitting direct connection to common sensor power rails. A resolution of 1024 PPR means one revolution produces 1,024 quadrature pulses that a controller can interpolate for fine incremental measurement. The sensing electronics support rotational input frequencies of at least 100 kHz, and output transitions occur in less than 1 µs, keeping edge distortion low at high counts. Continuous operation is allowed at shaft speeds up to 3600 rpm, while the starting torque of 5.0 oz-in minimizes breakaway drag on lightly coupled systems. Functional performance is maintained at relative humidity levels as high as 98 percent.

The encoder tolerates an axial thrust load of 30 lb and a radial side load of 40 lb, enabling direct clamping to gearboxes or motor stub shafts without auxiliary bearings. Once in motion, friction remains low because running torque does not exceed 4.5 oz-in, which reduces heat generation and bearing wear. The complete assembly weighs 16 oz, so it adds little inertia to the drive train and simplifies installation on small-frame motors. The permitted shaft loads accommodate forces from direct mounting and normal machine operation. Low running torque also limits resistance against the connected shaft during continuous rotation.
