Product Description:
The HS35R1024E507PS is a hollow-shaft incremental encoder produced by Danaher within the Dynapar Encoders series. It installs on a motor or shaft extension. The encoder converts mechanical rotation into conditioned pulse trains for PLCs, drives, and motion controllers that need position or speed feedback in automated equipment.
The housing is sealed to NEMA 4/IP66, so airborne dust or directed washdown water will not reach the sensing electronics. Internal optics deliver a line count of 1024 PPR, giving controllers one thousand twenty-four discrete position updates per revolution. High-speed detection is possible because the signal chain sustains a minimum response frequency of 100 kHz. Mechanical overruns are accepted at speeds up to 3600 rpm, matching common induction motor outputs. The shaft bearings tolerate axial coupling forces up to 30 lb, while running torque is limited to 4.5 oz-in to reduce drag on small motors. Electrical timing maintains a quadrature phase of 90° ±22.5° and pulse symmetry of 180° ±18°, ensuring consistent duty cycles for differential receivers. Operation can continue at 98% relative humidity without signal degradation.
The encoder supports a radial load of 40 lb, allowing installation on belted or pulley-driven systems without premature bearing wear. The optical module withstands shocks of 50 G for 11 ms and random vibration levels up to 20 G, so conveyor impacts or mobile machinery jolts do not disrupt edge spacing. Startup friction peaks at 5.0 oz-in, which is important when the encoder is mounted on low-torque servo motors. Total mass remains at or below 16 oz, reducing the load imposed by cantilevered arrangements on small-diameter shafts. The hollow-shaft mounting arrangement allows the encoder to fit directly over a compatible rotating shaft without requiring a separate flexible coupling. Its conditioned pulse output provides the timing information needed for accurate position tracking and speed measurement under continuous motion, mechanical stress, and moisture exposure.
