The HS35AY1FDU1DA000 is an incremental encoder with a 1-inch (25.4 mm) hollow bore, used for motor speed measurement and position feedback. For this model, we can manufacture a custom replacement matched to the original mechanical mounting, output signals, and electrical connection for equipment maintenance and spare-part replacement.
This configuration provides 1024 PPR with a 7272 line driver, delivering A and B channels and their complementary signals, together with a Z index pulse and its complementary signal. The custom encoder matches the original pulse count, output levels, and index signal to meet the existing control system’s feedback requirements.
Connection option D specifies a 10-pin MS connector with a mating plug and Dynapar HS35 phasing. The custom design must match both the pin assignments and the A/B phase relationship. Even when the connector and pulse count are identical, incorrect phasing can reverse the direction feedback, making phasing an essential requirement for plug-and-play replacement.
The mechanical configuration includes a protective basket and an anti-rotation tether kit for fan-cover mounting, matched to the original clamping position and tether attachment points. The original 1-inch insulating shaft insert is factory-installed and cannot be removed or exchanged to resize the bore. The custom design matches the equipment’s actual shaft diameter while retaining the shaft-current isolation arrangement and required installation space.
The original model operates at 5–28 VDC, while the custom replacement uses 10–30 VDC. All other configuration details are matched to the original model. Where the supply voltage meets this requirement, the replacement can use the existing mounting position and plug connection. If the equipment uses a 5 VDC supply, the power supply must be adjusted first.
