"Control Knob Stem Inspection

These control knob stems are shiny metal, and the C-clips are black oxidized metal. The control knob assemblies ***are indexed***, one at a time, into position in front of the PresencePLUS inspection sensor. Control knob assemblies which are missing the C-clip register fewer black pixels. The XXX sensor responds to a missing C-clip by energizing an alarm, which alerts the machine operator to remove the knob assembly from the work flow and place it into a rework bin."

...what's the meaning of the verb index in this context? poistion?

See explanation below...

It means that they are positioned one at a time in regular positions in front of the sensor --- the idea of 'index' means that they are probably held in some kind of device that positions them correctly --- it's the same idea as hole-punched computer printout paper being 'indexed' by the pins on the printer wheels

'indexing' always conveys this idea of 'confining to a set position' --- a control wheel might go round smoothly, or it might be designed to go round stopping in certain notched positions --- it is said to be 'indexed'

agree Elevenít (X) : I think the collocations 'alignment assemblies' and 'index assemblies' are pretty close in meaning, but index is certainly more exact. An alignment assembly will also control position, but is more engineering than elecronics

Thanks, CS! As a collocation, yes --- but the verbs would NOT be so interchangeable... Plus 'aligned' has other meanings in electronics...
agree Can Altinbay : Best answer. Blue ribbon entry. :)

\"moved step by step\"
Peer comment(s):

neutral Tony M : 'moved step by step' is OK, but 'adjusted' is not quite the same basic idea...

aligned

seems to read better.
Peer comment(s):

agree Tony M : Yes, although to me 'indexed' conveys the idea of a regular sequence of accurate positionings...
