It's a sensor for counting the notches in a rail on the floor of the
library for positioning the carriage along the X-axis.

Sorry about the crap focusing.  Angle and illumination are a bit of
trouble inside the cabinet, even with the panels removed.

There you can see the notched rail, and on the bottom of the near side
of the carriage is a sensor shaped line an inverted U.  During transport
(the carriage wasn't locked), it got bumped hard enough to be knocked
out of line, so the carriage doesn't alwayws count the proper number of
notches and ends up banging against the front of the cabinet.  I've
tried disassembling and realigning the parts (even with the shroud off,
in case it's bent enough to get in the way), and can't get it to work
reliably.

The Optek part number is OPB 810W51, which seems to still be a current
part, but I haven't found anyone that will sell them to me in qty < 100.
