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.
Vibration 55Hz, 1mm amplitude, 3 planes

protection
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.
S CE marked for all applicable
directives
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).
