Description
Bulletin 871L inductive proximity sensors are self-contained,
general purpose, solid state devices. These devices are
designed for most industrial applications where it is required to
sense the presence of metal objects (ferrous and non-ferrous)
without touching them.
The 871L limit switch style provides mounting
interchangeability, easy to wire terminations, rugged
construction, and superior sealing. The 25 (twenty-five)
position sensing head allows for twenty-four side views and
one top view.
Diagnostics
Green on indicates power on.
Orange on indicates output is energized.
Green flashing indicates short circuit or overload.
