GX-8ML□
Long sensing range
The non-shielded type (GX-8ML□) has twice the sensing
range of the shielded type (GX-8M□), although having
the same size. Hence, it allows margin against sensing
distance variations.

PRECAUTIONS FOR PROPER USE
• Never use this product as a sensing device
for personnel protection.
• In case of using sensing devices for
personnel protection, use products which
meet laws and standards, such as OSHA,
ANSI or IEC etc., for personnel protection
applicable in each region or country.
Mounting with set screw
• Tighten the set screw on the flat surface of the sensor
without applying excessive force. Make sure to use a set
screw with a cup-point end.
Set screw
(M4 or less)
(Note)
• Note that the maximum tightening torque differs
according to the location of the nuts.

• The root truncation of the threads with GX-8M□ and
GX-8ML□ is shallow owing to strengthening of the
sensors against tightening.
When tapping holes on equipment to fix the sensors, the
prepared holes must be ø7.2 mm ø0.283 in or more.

• The sensing range is specified for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coefficient
specified below. Further, the sensing range also changes
if the sensing object is smaller than the standard sensing

• Do not use during the initial transient time (10 ms) after
the power supply is switched on.
• Make sure that stress by forcible bend or pulling is not
applied directly to the sensor cable joint.
• GX-3S□, GX-4S□ and GX-5M□ do not incorporate
a short-circuit protection circuit at the output. Do not
connect them directly to a power supply or a capacitive
load.
