Maintenance

Aside from cleaning of the surfaces protecting the front of
the lens, the Balluff Light Array
requires only minimal maintenance.
The emitter and receiver windows should be kept clear of
contamination (dust, fingerprints, etc.). If cleaning is
needed, wipe the windows with a lint-free cloth and
alcohol, (ethanol, isopropanol). Do not use acetone!
Test object positioned at various points along the emitter-receiver axis.
*2)
Given is the maximum deviation of the diameter from the arithmetic mean
of all measurement values which were obtained over the entire distance
range. Test objects: Steel cylinders (diameter d = 8 mm) and steel wires
(d = 1 mm).
Same test object (steel cylinder d = 8 mm) positioned several times in the

light band (at the center half-way between the emitter and receiver;
permissible position deviation: ±2.5 % of the emitter-receiver distance).
