Description
Bulletin 871C inductive proximity
sensors are self-contained, general
purpose, solid-state devices designed
to sense the presence of ferrous and
non-ferrous metal objects without
touching them.
The switch body consists of a plastic
face and either a nickel-plated brass
barrel or plastic barrel. The electronic
circuitry is potted for protection against
shock, vibration, and contamination.
These sensors are available in 3, 4, 5,
8, 12, 18 and 30mm diameters, with
smooth or threaded barrels. Connection
options include a 2m cable, micro
quick-disconnect, and pico
quick-disconnect.

Description
Bulletin 871C inductive proximity
sensors are self-contained, solid state
devices designed for most industrial
applications where it is required to
sense the presence of metal objects
without touching them. These special
extended temperature models are ideal
for industrial environments where
temperatures can reach as high as
212_F (100_C) or as low as –40_F
(–40_C). They are available for current
source (PNP) operation with a normally
open output.
Each switch has a plastic face and a
nickel-plated brass housing which meet
NEMA 1, 2, 3, 4, 12, 13 and IP67 (IEC
529) enclosure standards. The
electronic circuitry is potted for
protection against shock, vibration, and
contamination.
These sensors are available in 12, 18,
and 30mm diameters. Connection
options include: 2m (6.5ft) PUR cable or
micro quick-disconnect (4 pin,
1 keyway).

871C Cable Style
12, 18, 30mm
Description
Bulletin 871C inductive proximity
sensors are self-contained, solid-state
devices designed to sense the
presence of metal objects without
touching them. This special version
provides a 0–10V sourcing analog
output proportional to the sensing
distance.
This device is enclosed by a plastic
face and a nickel-plated brass housing
which meets NEMA 1, 2, 3, 4, 12, 13
and IP67 (IEC 529) enclosure
standards. The electronic circuitry is
potted for protection against shock,
vibration and contamination.
This sensor is available in 12, 18 and
30mm diameters with a 2m (6.5ft.) PVC
cable connection.
