Product Description:

The HS35R50007267 is an incremental hollow-shaft rotary encoder produced by Danaher for the Dynapar Encoders series. Installed on the nondrive end of a motor or on a line shaft, it converts mechanical rotation into square-wave electrical pulses so drives and PLCs can monitor speed and direction with high resolution. The unit’s through-bore and flexible tether make it a direct-mount feedback element for conveyors, winders, and general motion-control axes where precise position data are required.

The aluminum housing carries a protection rating of NEMA 4/IP66, so the internal optics remain sealed against dust ingress and high-pressure washdown. The bearing sets tolerate an axial shaft load of 30 lb and a radial shaft load of 40 lb, allowing the encoder to withstand belt tension or coupling side forces without premature wear. The signal electronics support a minimum frequency response of 100 kHz. At this rate, each channel can reproduce one hundred thousand transitions per second, permitting reliable counting even when the shaft turns at the device’s mechanical speed limit of 3600 rpm. The quadrature outputs maintain a phase separation of 90° ±22.5° electrical, ensuring orthogonal phasing for accurate bidirectional decoding. Starting friction is limited to 5.0 oz-in, so drive torque losses remain minimal during startup.

The encoder withstands shocks up to 50 G for 11 ms, while running torque stays below 4.5 oz-in to keep steady-state drag negligible. A higher breakaway torque of 5.0 oz-in indicates the maximum moment needed to initiate motion after long stops. Output edges have a rise and fall time of less than 1 µs, providing clean transitions for high-speed counters. Channel symmetry remains at 180° ±18° electrical, and channel A leads channel B during clockwise rotation to simplify wiring conventions. The precision-ground bore accepts shafts within a tolerance range of +0.0003 to +0.0005 in. The fully assembled unit weighs no more than 16 oz, reducing strain on the host machine.
