Product Description:
The HS35R0360H341 is a hollow-shaft incremental encoder manufactured by Danaher for the Dynapar Encoders series. By generating equally spaced output pulses, the device supplies velocity, direction, and position feedback to drives and PLCs that regulate motors and mechanical axes. Its through-bore construction allows the encoder to slide over a host shaft, reducing coupling hardware and making it suitable for compact conveyor, printing, and packaging machinery.
The encoder has a resolution of 360 PPR, so the control system receives 360 pulses for each shaft revolution, enabling moderate positional granularity without excessive count rates. A minimum frequency response of 100 kHz lets the electronics process those pulses even when the shaft spins at the rated 3600 rpm. The enclosure meets NEMA 4 / IP66 sealing requirements, protecting the optics against dust and high-pressure washdown. The 1-1/8 in bore is machined to a nominal tolerance of +0.0003 to +0.0005 in, providing a close fit that limits vibration transfer. The encoder has a maximum running torque of 4.5 oz-in, and starting torque is limited to 5.0 oz-in, so it imposes minimal drag on the host motor. Shaft runout is limited to ±0.025 in, maintaining even sensor gaps during rotation.
The encoder has an axial load capacity of 30 lb and a radial load limit of 40 lb, allowing it to tolerate belt tension or minor pulley side loads without bearing damage. Its moment of inertia is 25.6 × 10-4 oz-in-s², so rapid acceleration cycles do not add significant inertial load to the drivetrain. A shaft endplay allowance of ±0.050 in maintains internal clearances during thermal expansion and helps prevent contact between rotating components. Despite its metal housing and sealed bearings, the encoder has a maximum mass of less than 16 oz, reducing the load on small motor frames and minimizing cantilever stress on the mounting bracket.
