PRECAUTIONS FOR PROPER USE
Refer to p.1012 ~ for general precautions.
Mounting
GX-8 type
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.
•
•
Make sure to use a M3
(length: 12 mm
0.472 in or
more) truss head screw.
The tightening torque
should be 0.7 N·m or less.
Do not use a fl at head
screw or a pan head
screw.

Infl uence of surrounding metal
When there is a metal near the sensor, keep the minimum
separation distance specifi ed below.

Sensing range
The sensing range is specifi ed for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coeffi cient
specifi ed below. Further, the sensing range also changes
if the sensing object is smaller than the standard sensing
object or if the sensing object is plated.

Notes: 1) “I” in the model No. specifi es
the different frequency type.
2) Close mounting is possible for up
to two sensors.
When mounting three sensors or more at
an equal spacing, align the model with “I”
and the model without “I” alternately. The
minimum value of dimension “H” should
be as given below.
