Cautions For 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

GX-6 type

Use the optional sensor mounting bracket when installing.

<When using MS-GX6-1 (Optional / recommended)>

To mount the sensor with a nut, the mounting hole diameter should be ø3.4 mm ø0.134 in.

[1]	Insert the sensor into the bracket as shown on the right.
[2]	Push the sensor until the bracket hook is lodged in the groove on the upper portion of the sensor.
[3]	Fix the bracket in place with M3 pan head screw.

<When using MS-GL6-1(Optional) /MS-GL6-2 (Optional)>

To mount the sensor with a nut, the mounting hole diameter should be ø3.4 mm ø0.134 in.

GX-8 type

<When using MS-GXL8-4 (Optional)>

Make sure to use a M3 (length: 12 mm 0.472 in or more) truss head screw (accessory for MS-GXL8-4).
The tightening torque should be 0.7 N·m or less.
(Do not use a flat head screw or a pan head screw.)

Note:Do not use a spring washer between the mounting screw and product.

GX-12 type

The tightening torque should be 0.7 N·m or less.
To mount the sensor with a nut, the mounting hole diameter should be ø3.4 mm ø0.134 in. Further, the hole in which the boss is inserted should be ø2.5 mm ø0.098 in and 3 mm 0.118 in, or more, deep.

Note:Do not use a spring washer between the mounting screw and product.

GX-15 type

The tightening torque should be 1 N·m or less.
To mount the sensor with a nut, the mounting hole diameter should be ø3.4 mm ø0.134 in.

Note:Do not use a spring washer between the mounting screw and product.

When installing the long sensing range type on iron or stainless steel plate, put the optional aluminum sheet in between the sensor and the plate.

Influence of surrounding metal

When there is a metal near the sensor, keep the minimum separation distance specified below.

Front sensing type

	GX-F6 type	GX-F8 type	GX-F12 type	GX-F15 type	GX-FL15 type
A	6 mm 0.236 in (Note 1)	7.4 mm 0.291 in	7.1 mm 0.280 in	8 mm 0.315 in	8 mm 0.315 in (Note 2)
B	8 mm 0.315 in	8 mm 0.315 in	20 mm 0.787 in	20 mm 0.787 in	30 mm 1.181 in
C	3 mm 0.118 in	3 mm 0.118 in	7 mm 0.276 in	7 mm 0.276 in	10 mm 0.394 in

Notes:

1)	When using MS-GX6-1 (recommended mounting bracket, optional), the distance “A” including the thickness of mounting bracket will be 6.4 mm 0.252 in.
2)	The GXL-FL15 type should be mounted on an insulator. To mount it on an iron or stainless steel, use the enclosed aluminum sheet.

D	3 mm 0.118 in	4 mm 0.157 in	7 mm 0.276 in	6 mm 0.236 in	12 mm 0.472 in
E	10 mm 0.394 in	10 mm 0.394 in	20 mm 0.787 in	20 mm 0.787 in	30 mm 1.181 in

G	2 mm 0.079 in	3 mm 0.118 in	3 mm 0.118 in	3 mm 0.118 in	10 mm 0.394 in

Note:	When GX-HL15 type is mounted on an insulator or seated on the enclosed aluminum sheet, the distance “F” can be zero.

Mutual interference prevention

When two or more sensors are installed in parallel or face to face, keep the minimum separation distance specified below to avoid mutual interference.

Notes:

1)	“I” in the model No. specifies 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. GX-F6 / H6 type: 3.5mm 0.138 in GX-F8 / H8 type: 6mm 0.236 in GX-F12 / H12 type: 6.5mm 0.256 in GX-F15 / H15 type: 15mm 0.591 in GX-FL15 / HL15 type: 47.5mm 1.870 in

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.
