Suitable for high-speed applications
IP67G sensor head variations
It has a high performance of 3.3 kHz response
frequency. These sensors are ideal for sensing objects
moving at high speeds.
The lineup includes 5 different models, from an ultracompact 2.8 mm 0.110 in diameter type to a spatterresistant type. Furthermore, all except for the GH-2SE
are IP67G oil-resistant models so that they can be used
with confidence even in adverse environments.

Excellent workability and ease of maintenance
They all have the same form as the FX-300 series of fiber sensors. The quick-connection cables are also of the same
shape, so that fiber sensors and laser sensors can all be used together and less power supply wiring is required.
Quick-connection cables can be used
for power supply cascade wiring. Both
main and sub units utilize
the same amplifier body.

Sub cable
As the sub cable contains only one output wire, a great amount of wiring and space can be saved.
Labor-saving by one-touch connections
The connection between the sensor head and the
amplifier is made using a quick-connection connector.
Past troublesome wiring connections using a screwdriver
are no longer necessary.

As the sensing object size becomes
smaller than the standard size
(iron sheet 10 × 10 × t 1 mm 0.394
× 0.394 × t 0.039 in), the sensing
range shortens as shown in the left
figure.
The graph on the left is plotted
with the sensitivity adjusted so as
to just detect a 10 × 10 × t 1 mm
0.394 × 0.394 × t 0.039 in iron
sheet placed at a distance of
2.0 mm 0.079 in.

Guide
• 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.

• Do not use during the initial transient time (0.5 sec.) after
the power supply is switched on.
• Do not use the sensor at places having intense
vibrations, as this can cause malfunction.
• Make sure that stress by forcible bend or pulling is not
applied directly to the cable joint of the sensor head.
