H5D Differential Heavy Duty Optical Shaft Encoder Description: The H5D differential optical incremental encoder is fully assembled with a shaft, two 1/4" ID by 1/2" OD heavy duty ball bearings and a mounting plate. This design tolerates increased radial and axial loads. This design also allows for an optional rear shaft extension. The mounting plate comes with 2 mounting holes for screws #6 or smaller. The mating connector has 10 pins, is polarized and latches into the encoder. Depressing the latch tab allows the connector to be unplugged. Mating connector assemblies are available from US Digital stock as shown on the Cables & Connectors data sheet. Custom cables are also readily available. The H5D has an internal differential line driver (26C31) that can source and sink 20mA at TTL levels. The cable that connects to this encoder should have 3 twisted pairs plus power and ground. Group each pair of differential signals. The recommended receiver is industry standard 26C32. Maximum noise immunity is achieved when the differential receiver has a 110 Ohm resistor in series with a .0047mf capacitor placed across each differential pair. The capacitor simply conserves power; otherwise power consumption would increase by 45mA per pair, or 140 mA for 3 pairs.
