ABSTRACT:
A mechanism for sensing that all the leads of a dual-in-line electrical component are in their proper position projecting through the appropriate openings in a printed circuit board. The sensor uses fiber optics to indicate that all the leads are properly positioned by using light reflected from the lead to activate a photo transistor which indicates to the computer controlling the machine operation that all the leads are properly positioned.
