Description
Background suppression sensing is designed to sense small
objects over a short range. Objects beyond its range of
sensing are generally rejected. The near and far limits of the
sensing range are dependent upon the reflectivity of the object
and the senstivity setting.
Two package sizes are available. Smaller 10.3mm x 15mm x
25.4mm sensors can be selected when precise, short range
sensing is required. Larger sensors offer greater sensing
ranges to 7.87in (200mm).
Each bulletin 42BA comes complete with a steel right angle
mounting bracket which provides a variety of mounting
options.
