IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.

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.
