HOA6480 Series Barcode Sensor
Infrared Products
DESCRIPTION
The HOA6480 Series is a reflective barcode sensor that incorporates a VCSEL (Vertical Cavity Surface-emitting Laser) emitter and phototransistor detector in a custommolded plastic package. The VCSEL technology allows the sensor to operate with a very low drive current. The phototransistor drives an operational amplifier with an open-collector output, providing users with flexibility in their interface designs.
The HOA6480 Series provides a digital output that allows it to be interfaced with most decoding equipment. The 4,5 mm [0.180 in] focal length allows measurement with no contact and the 0,254 mm [0.010 in] resolution works well in most barcode applications. The HOA6480 typical scan speed is 254,0 mm [10.0 in] per second. A choice of pin, wire or custom termination allows flexible interconnections and the reflective sensor configuration promotes easy mounting. POTENTIAL APPLICATIONS * Barcode verification in dispensing and processing equipment * Line or edge detection * Encoding * Data collection from manufacturing lines, robotic operations, production instrumentation/control units, automated sorting and screening equipment and analytical systems such as medical analysis. (Note that carbon black ink is required for this device to sense lines.)

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).
