PHOTOSWITCH® Bulletin 45PVA Part Verification Array

IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.

Description

The Allen-Bradley 45PVA is a photoelectric Parts Verification

Array designed for bin picking applications and object

detection in the parts assembly industry. When used as part of

a suitably configured bin-picking system, the 45PVA effectively

prevents mispicks to enhance efficiency and minimize down

time. It is also the ideal solution to address the “error proofing”

initiatives prevalent in the automotive industry.

The 45PVA uses an array of LEDs to create a light screen that

can be spanned across bins at an assembly station. By

mounting the sensors on parts bins and wiring them into a

controller programmed with the necessary logic, a virtually

error-free bin-picking process can be achieved. ‘Job lights’ on

the 45PVA will not only show the assembler the bins required

to complete the current process, but will also indicate the

correct picking sequence. In the event the assembler attempts

to pick an incorrect part, a selectable warning light on the

45PVA will illuminate to indicate the error; additional fault

enunciation can be achieved via controller logic in conjunction

with a tower light or audible alarm.

In addition to increasing efficiency and quality control by

preventing faults in the bin-picking process, the 45PVA is

instrumental in personnel stress reduction and the

simplification of personnel training—especially in multi-lingual

facilities.

Features

S Robust metal enclosure with super slim 13mm profile

S Large highly-visible job indicator lights

S Optional Red warning light indicator to notify operator of

incorrect component selection

S Dip switch selectable lighting operation for job lights

S Transmitted beam or selectable retroreflective/diffuse

sensing modes

S NPN or PNP dip switch selectable output reduces inventory

S Two frequency dip switch selectable cross talk protection

S Different sizes are available for different component racks.

Transmitted beam models are available in four sizes (100

mm (4 in), 225 mm (9 in), 300 mm (12 in), and 375 mm (15

in)). Retroreflective/diffuse models are available in two

sizes (100 mm (4 in) and 225 mm (9 in)).
