Product Description:

The HS35R0060F300 is a hollow-shaft incremental encoder produced by Danaher within the Dynapar Encoders series. In automated machinery, this sensing element attaches directly to a motor or spindle shaft and converts mechanical rotation into a train of electrical pulses. A drive, PLC, or motion controller counts these pulses for speed or position feedback, enabling closed-loop regulation and event timing across conveyors, presses, and packaging lines.

The external body measures 3.54 in in diameter and fits shafts with a tolerance range of +0.0003 to +0.0005 in to achieve concentric mounting. Supported shaft insertion depth ranges from 1.25 in to 2.0 in, allowing the encoder to clear shoulders or collars without spacers. The code wheel produces 60 PPR, which can provide 240 edges to the host electronics when quadrature decoding is used. High-speed detection is possible because the sensing electronics support a frequency of at least 100 kHz, while the mechanical speed is limited to 3600 rpm. The sealed NEMA 4/IP66 housing protects the internal optics from dust and water jets during operation. Starting torque is limited to 5.0 oz-in, and running torque falls to 4.5 oz-in after rotation begins, reducing the load placed on the drive shaft.

The hollow hub withstands an axial load of 30 lb and a radial load of 40 lb, helping prevent shaft misalignment from distorting the code disk. The encoder can absorb mechanical shocks of up to 50 G for 11 ms without losing signal integrity. Its total mass is limited to 16 oz, which reduces the weight supported by the mounting assembly and helps moderate vibration. The allowable shaft insertion range provides sufficient engagement with the clamp while maintaining clearance around adjacent shoulders and collars. Low starting and running torque also reduce resistance at the shaft during continuous operation, helping limit unnecessary bearing load.
