Differential Heavy Duty Optical Shaft Encoder
H5D
Description:
Features:
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.
Ø Small size
Ø Low cost
Ø Optional Agilent compatible pin-out
Ø Positive finger-latching polarized connector
Ø 2-channel quadrature, TTL squarewave outputs
Ø 3rd channel index option
The mating connector has 10 pins, is polarized and latches into the encoder. Depressing the
latch tab allows the connector to be unplugged.
Ø Differential line driver outputs
Ø Tracks from 0 to 100,000 cycles/sec
Ø Heavy duty ball bearings track up to 10,000 RPM
Ø -40 to +100°C operating temperature
Ø Single +5VDC supply
Ø US Digital warrants its products against defects and work-
manship for two years. See complete warranty for details.
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.
