Inductive Proximity Sensors

Description
Bulletin
871F inductive flat pack and
block style proximity sensors are
self-contained, solid state devices.
These devices are designed for most
applications where it is required to
sense the presence of ferrous and
nonferrous metal objects without
touching them.
The body material is either plastic (flat
pack) or aluminum (block) and meets
NEMA 4, 13 and IP67 (IEC 529)
enclosure standards. The electronic
circuitry is potted for protection against
shock, vibration, and contamination.
Connection options include a micro and
mini quick-disconnect, T
oughLinkt and
PVC cable models, and both 1/2–14
NPT and PG13.5 conduit opening with
screw terminals.

Description
Bulletin
871F inductive proximity
sensors are self-contained, solid-state
devices designed to sense the
presence of ferrous and nonferrous
metal objects without touching them.
These special weld–field immune
models are ideal for welding
environments and other applications
where large magnetic fields are present.
They are rated for reliable operation at
a 1in distance from a current in line
carrying 20,000A.
Ê
Each sensor is housed by an aluminum
body which meets NEMA 4, 13, and
IP67 (IEC 529) enclosure standards. It
is equipped with a green LED to
indicate power and an orange LED
which lights when the output is
energized.
