Product Description:
The HS35R10004346 is a hollow-shaft incremental encoder produced by Danaher for the Dynapar Encoders series. Designed for direct coupling to motor or machine shafts, the unit converts rotational motion into dual quadrature pulse trains that allow drives, PLCs, and indexing systems to monitor position and velocity with digital accuracy inside automated production lines. Its compact form and hollow bore simplify installation on existing shafts without requiring additional couplings.
A resolution of 1000 PPR provides 0.36° mechanical increments, supporting moderate accuracy requirements for conveyors and forming machines. The output electronics process encoder signals at frequencies up to 100 kHz, allowing high-speed controllers to sample position accurately. The code disk can spin continuously at 3600 rpm. The enclosure meets NEMA 4/IP66 requirements, blocking airborne dust and low-pressure water jets when the encoder is mounted outside a cabinet. Maximum starting torque is limited to 5.0 oz-in, reducing the load placed on small-frame motors during acceleration. Quadrature phasing is 90° ±22.5° electrical, and symmetry remains within 180° ±18° electrical, keeping the timing between channels A and B consistent for bidirectional counting.
The encoder accepts a minimum shaft engagement of 1.25 inches and a bore tolerance range of +0.0003 to +0.0005 inches, allowing slip-fit mounting. Dynamic alignment is supported by a shaft runout limit of ±0.025 in, while permissible shaft endplay is ±0.050 inches. The bearings support loads of up to 40 lb radial and 30 lb axial, making direct installation possible on moderate-duty equipment. During operation, friction is capped at 4.5 oz-in of torque, so continuous drag remains below the motor’s usable torque margin. The housing and disk assembly weigh no more than 16 ounces, minimizing the additional inertia placed on the shaft. These operating limits help preserve signal stability when the encoder is exposed to normal shaft movement and sustained rotation.
