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.
