TESTING PROCESS
Each HOA6480 Barcode Sensor is precisely tested
using automated testing equipment and a custom
fixture.
During the testing process, the test fixture holds each
sensor at a distance of approximately 4,5 mm
[0.180 in] from a rotating wheel with a diameter of
89,0 mm [3.5 in] and a height of 15,2 mm [0.600 in].
One half of the wheel consists of a 50 % duty cycle
barcode of alternating black and white stripes of the
same size (0,38 mm [0.015 in] wide and 16,2 mm
[0.600 in] tall). The other half of the wheel has a
sample barcode of a known value.
The wheel rotates at 1 RPS (~254,0 mm [10.0 in] per
second). Power, ground and output connections are
applied to the sensor loaded into the test fixture.
Custom software in the test system evaluates the
duty cycle collected by the sensor and sets the
desired duty cycle between 40 % and 60 %. The
software then reads a sample barcode and verifies
that an accurate and complete barcode signal has
been collected.
REFLECTIVITY
The sensor output will be below 1.1 V when
presented with a 50 % reflective surface at 6,35 mm
[0.250 in] (Kodak Grey Scale #3, CAT 152 7662).
