ENVIRONMENTAL RESISTANCE
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.

(Compared with conventional models) GX-□-R
The bending durability of the cable to repeated bending
has been increased tenfold by using special alloy cores
for the cable.

Flexible cable type
Flexible cable type is also available for shielded type.
When ordering this type, suffix “-R” to the model No.
(e.g.) Flexible cable type of GX-3S is “GX-3S-R”.
5 m 16.404 ft cable length type
5 m 16.404 ft cable length type (standard: 3 m 9.843 ft) is also available. (excluding GX-4SB)
When ordering this type, suffix “-C5” to the model No.
(e.g.) 5 m 16.404 ft cable length type of GX-3S is “GX-3S-C5”.

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.

• 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

• 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.
