Product Description:
The HS352048844B7 is an incremental hollow-shaft encoder produced by Danaher for the Dynapar Encoders series. It mounts directly on a rotating shaft and converts mechanical motion into square-wave electrical signals that a drive or PLC counts to calculate angular position and velocity. In industrial automation, this feedback supports precise speed regulation, axis synchronization, and automated positioning without extra gearing or secondary sensors. Its compact, sealed housing is suitable for packaging, material-handling, and general factory equipment where dependable motion feedback is required.
The encoder provides 2048 pulses per revolution, giving the controller a position granularity of approximately 0.18 degrees per count. Its high-speed electronics support a minimum frequency response of 100 kHz, allowing the encoder to deliver its full resolution while the shaft turns rapidly. Differential signaling is provided by a 7272 line driver, which has a specified output current of 40 mA and a maximum input current draw of 100 mA. This circuit maintains clean signal edges over long cable runs and helps reduce the effects of electrical noise. The IP66 enclosure is dust-tight and resists powerful water jets. Internal components support continuous operation at temperatures up to 100 °C, allowing installation near motors or gearboxes where surrounding temperatures may rise. Quadrature outputs are available through channels A and B with complementary signals, while an index Z pulse supports direction detection and homing routines.
The hollow shaft supports an allowable axial load of 30 lb and a radial load of 40 lb, helping protect the bearings when couplings or belt-driven components apply force to the assembly. The encoder tolerates rotational speeds up to 3600 rpm, which accommodates the base speeds of many industrial induction motors. Electrical termination uses a 10-pin connector with a mating half, allowing the cable connection to be disconnected without disturbing the encoder mounting. Installation uses a 5/8-inch bore, a 5.88-inch bolt circle, and 3/8-inch clearance mounting holes. These dimensions allow the unit to fit common NEMA C-face adapters without additional brackets while maintaining direct alignment with the rotating shaft.
