Description

The ADNS-2001 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 mathematic-

ally 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 ADNS-2001

offers a PS/2 or quadrature output

mode for interface flexibility.

Resolution is specified as 400 cpi

at rates of motion up to 16 inches

per second.
