Close mounting
Protection structure IP67G
Two sensors can be mounted close together because
different frequency type are available.
GL-18H/18HL type are resistant to oil and have a
protection structure IP67G.
The GL-18HL type can be mounted with a space of
20 mm 0.787 in between the two sensors.
The GL series incorporates an operation indicator (red)
for operation check.
GL-18HL type offers a long sensing range of 12 mm
0.472 in.
Small variations in the positions of the sensing objects
do not affect detection.

• 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.
