Product Description:

The HS35R10245341 is a hollow-shaft incremental encoder produced by Danaher within the Dynapar Encoders series. In automation systems, the unit attaches to a motor or driven shaft and converts mechanical rotation into differential electrical pulses so that motion controllers can monitor position and speed with high accuracy. By providing incremental feedback, the device enables closed-loop regulation in conveyors, packaging lines, and general machinery.

Its optical disk provides 1024 PPR, so each full revolution is divided into 1,024 quadrature pulse pairs that the drive interprets as incremental counts. The internal circuitry supports a minimum frequency response of 100 kHz, allowing high-speed counting without missed edges as the shaft approaches its maximum mechanical speed of 3600 rpm. A 7272 line driver supplies the differential AB channels, providing balanced signals for noise immunity over long cables. Protection from dust and water jets is provided by the NEMA 4/IP66 housing, enabling installation on exposed equipment frames. The encoder uses a differential AB output format with a rise and fall time of less than 1 microsecond, providing sharp transitions for accurate edge detection.

Logic circuits draw a maximum current of 100 mA, reducing heat generation inside sealed enclosures. During startup, shaft movement is resisted by a maximum torque of only 5.0 oz-in, minimizing the load on small servo bearings. The hollow hub tolerates an axial thrust of 30 lb and a radial side load of 40 lb, helping protect the bearings from coupling misalignment or belt tension. A bore tolerance of +0.0003/+0.0005 in provides a precise fit on the host shaft, while a 7-pin connector permits quick electrical termination. The aluminum body and internal disk keep the total weight at 16 oz, reducing the mounting load on light-duty motors.
