IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.

Description

The 42CF is a family of general purpose photoelectric sensors
intended for light to medium duty industrial applications. They
are packaged in an industry standard 12mm cylindrical
housing.

Three possible modes of sensing include transmitted beam,
diffuse and polarized retroreflective, allow the 42CF to be
used in a variety of complex applications.

Indication of target presence is provided through a discrete
NPN or PNP output which is compatible with most
measurement and control circuits found in today’s factory
automation systems. Outputs are short-circuit protected to
provide continuous operation even under unexpected
conditions.
