Product Description:

The HS35R102483E2 is a hollow-shaft rotary encoder produced by Danaher within the Dynapar Encoders series. In motion-control systems, it attaches directly to a motor or machine shaft and converts mechanical rotation into electronic position and speed signals for drives, PLCs, or counters. By providing clean quadrature outputs, the unit allows controllers to measure incremental movement and establish accurate feedback loops in conveyors, packaging equipment, and assembly lines where position accuracy and repeatable speed are critical to throughput.

The encoder slips over a shaft through its 5/8-inch bore, and the bore tolerance of +0.0003/+0.0005 inch ensures tight coupling without requiring excessive force. Its housing is rated NEMA 4/IP66, meaning the seals resist dust ingress and high-pressure washdown. The resolution is 1024 PPR, so one mechanical revolution generates 1,024 pulses for fine incremental measurement. A minimum frequency response of 100 kHz allows the electronics to handle fast pulse trains without distortion, while a rise and fall time of <1 µs keeps signal edges sharp for high-speed counting. The code wheel may spin at up to 3600 rpm, matching typical motor speeds in light industrial machinery without oversaturating the sensor electronics.

The mechanical interface protects the bearings and helps preserve measurement accuracy. The hollow hub withstands axial loads of 30 lb and radial side loads of 40 lb, accommodating typical belt-drive and coupling stresses. Starting torque does not exceed 5.0 oz-in, and running torque is limited to 4.5 oz-in, so the encoder imposes minimal drag on the host shaft. Electrical symmetry is specified at 180° ±18°, while quadrature phasing is specified at 90° ±22.5° to maintain consistent duty cycles across the full count. The unit weighs no more than 16 oz, allowing direct mounting on small servo motors without additional supports.
