Product Description:
The HS35R102480P7B is a hollow-shaft incremental encoder produced by Danaher for the Dynapar Encoders series. It mounts directly on a motor or machine shaft and converts mechanical rotation into digital quadrature signals that a drive or PLC counts for speed, direction, and position feedback in automated equipment. A NEMA 4 / IP66 housing protects the sensing head from dust and water, making the encoder suitable for demanding industrial settings where airborne debris or moisture may reach nearby equipment.
This model features a resolution of 1024 PPR, so the control system receives equally spaced pulses during every full turn of the shaft. Its output drivers sustain a minimum frequency response of 100 kHz, allowing high-speed equipment to be monitored without pulse loss. The encoder can mechanically turn at up to 3600 rpm, and its quadrature phasing is maintained at 90° ±22.5° electrical, keeping phase separation accurate for velocity calculation. Channel symmetry of 180° ±18° electrical holds the duty cycle near 50%, and the index window follows the same tolerance to mark the home position once per revolution. For direction information, channel A leads channel B during clockwise rotation. The bearing set tolerates axial shaft loads of up to 30 lb. Starting torque does not exceed 5.0 oz-in, minimizing the mechanical load placed on the connected drive system.
Radial loading capacity reaches 40 lb, allowing the unit to operate on pulley, gear, or belt arrangements without damaging the bearings. The square-wave outputs exhibit rise and fall times of <1 µs, keeping edge jitter low when long cables are present. During continuous rotation, the running torque remains below 4.5 oz-in, limiting frictional losses and heat generation. With a maximum weight of only 16 oz, the encoder adds little mass to small motors or compact machine assemblies. Because its code type is incremental, the control system must locate the index pulse at startup before establishing a reference position. Its low inertia and substantial bearing capacities accommodate frequent indexing and directional reversals in packaging machines, conveyors, and general motion axes.
