Description
The HDNS-2000 is a low-cost
reflective optical sensor that
provides a non-mechanical
tracking engine for implementing
a computer mouse.
It is based on optical navigation
technology which measures
changes in position by optically
acquiring sequential surface
images (frames) and mathemat-
ically determining the direction
and magnitude of movement. The
sensor is mounted in a plastic
optical package and designed to
be used with the HDNS-2100
(Lens), HDNS-2200 (LED
Assembly Clip), and HLMP-ED80
(High Light Output 639 nm
LED), providing a complete and
compact tracking engine. This
optical tracking engine has no
moving parts and requires
no precision optical alignment
enabling high volume system
assembly. The HDNS-2000 offers
a PS/2 or quadrature output
mode for interface flexibility.
Resolution is specified as 400 cpi
at rates of motion up to 12 inches
per second.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component
to prevent damage and/or degradation which may be induced by ESD.
