Product Description:

The HS351024844B7 hollow-shaft incremental encoder is produced by Danaher as part of the Dynapar Encoders series. It mounts on a machine or motor shaft and translates mechanical rotation into quadrature electrical pulses, providing motion controllers with real-time speed and direction information. By supplying a once-per-revolution index along with complementary A and B tracks, the device supports accurate homing, gearing, and velocity regulation tasks commonly required in industrial automation cells.

The code disc provides a resolution of 1024 PPR, meaning 1,024 incremental pulses are delivered per revolution for fine velocity and incremental distance measurement. The photodiode array and amplifier chain support a bandwidth of 100 kHz, so the encoder can reproduce high pulse rates without waveform distortion when shafts accelerate rapidly. The output uses a 7272 line driver that sources or sinks symmetrical currents across an input supply range of 5 VDC to 26 VDC. Mechanical attachment relies on a hollow bore of 5/8 in and a face-mount pattern on a 5.88 in bolt circle. The available differential signals are A, /A, B, /B, Z, and /Z, providing compatibility with standard motion amplifiers.

The housing carries a NEMA 4/IP66 rating, protecting the encoder against dust ingress and high-pressure washdown water. Internally lubricated bearings accommodate continuous operation at speeds up to 3600 rpm. The optical assembly maintains accuracy from 0 °C through the upper operating temperature of 100 °C. Rotational inertia is limited to 7.9 × 10⁻⁴ oz·in·s², keeping additional drive acceleration requirements low, while breakaway resistance is held to 5.0 oz-in of starting torque so servo loops remain responsive. A pre-molded 10-pin connector with a matching connector simplifies field termination and helps shield the differential signal pairs against electrical noise.
