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
GL-18H/18HL type
Refer to p.1579~ for general precautions.
Sensing range
• 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 object or if the
sensing object is plated.

• The tightening torque should
be 0.5 N·m or less.
• To mount the sensor with a
nut, the thru-hole diameter
should be ø3.4 mm
ø0.134 in.
• Screws, nuts or washers are
not supplied. Please

arrange them separately.

Wiring
• Please carry out the wiring carefully since protection
circuit against reverse power supply connection is not
incorporated.
• The output does not incorporate a short-circuit protection
circuit. Do not connect it directly to a power supply or a
capacitive load.
• Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching
regulator, ensure that the frame ground (F.G.) terminal of
the power supply is connected to an actual ground.
• In case noise generating equipment (switching regulator,
inverter motor, etc.) is used in the vicinity of this
sensor, connect the frame ground (F.G.) terminal of the
equipment to an actual ground.
• Do not run the wires together with high-voltage lines or
power lines or put them in the same raceway. This can
cause malfunction due to induction.
Others
• Do not use during the initial transient time (50ms) after
the power supply is switched on.
• Take care that the sensor does not come in direct contact
with oil, grease, or organic solvents, such as, thinner, etc.
• Make sure that the sensing end is not covered with metal
dust, scrap or spatter. It will result in malfunction.
• When there is a metal near the sensor, keep the
minimum separation distance specified below.
