Product Description:
The HS351024G54B7 incremental encoder is produced by Danaher within the Dynapar Encoders series. Designed for fan-cooled induction motors and other rotating equipment, it converts shaft position into digital quadrature signals for speed feedback in drives and PLC control loops. The unit installs over a 1 in hollow shaft bore, couples through a compression hub, and routes data through a 10-pin connector supplied with its mating plug. Differential A, A-complement, B, B-complement, Z, and Z-complement channels support precise index referencing, while the assembly weighs no more than 16 oz to minimize bearing load.
Resolution is set at 1024 counts per revolution, giving 0.35° edge granularity for velocity regulation. The output stage is a 5–26 V line driver (7272) that sources complementary signals suitable for long cable runs. A minimum frequency response of 100 kHz keeps the pulse train accurate at elevated speeds, and the protected housing carries a NEMA 4/IP66 rating that blocks dust and high-pressure washdown. Mechanical speed capability reaches 3600 rpm. Within that limit, the running torque stays below 4.5 oz-in, and initial motion requires no more than 5.0 oz-in of starting torque.
The rotating hardware withstands an axial thrust of 30 lb and a radial side load of 40 lb, making it suitable for belt-driven equipment or applications with overhung pulleys. Operation continues at ambient temperatures up to 100 °C when the applicable derating rules for the electronics are observed, and the sealing remains intact on humid production floors. Installation is simplified by the fan-cover motor mount, which aligns the encoder with common totally enclosed fan-cooled motor end bells and reduces the need for custom brackets. When installed on a burr-free shaft, the internal safety stop keeps dynamic loads within the bearing limits and helps preserve signal accuracy during prolonged duty cycles.
