Industry No. 1* in stable sensing

* Based on research conducted by SUNX as of August 2007 among equivalent rectangular Inductive sensors.

Can be installed with ample space

This sensor has the longest stable sensing range among the same level of rectangular inductive proximity sensors in the industry. It is easy to install the sensor.

Variation at the maximum operation distance is within ±8 %

Thorough adjustment and control of sensing sensitivity greatly reduces individual sensor differences and variations.

The work of adjusting sensor positions when using multiple sensors and when sensors have been replaced is much easier.

* Not including temperature characteristics. GX- 12 has a variation of 0.64 mm 0.025 in or less for a maximum operation distance of 4 mm 0.158 in

Temperature characteristics vary within ±8 %

Components such as the sensor coil and core and product design have been totally revised to provide excellent temperature characteristics. Stable sensing can be obtained regardless of the time of day or the yearly season.

APPLICATIONS

Muting control of light curtains

Positioning processing equipment

Positioning metal pallets

ENVIRONMENTAL RESISTANCE

10 times the durability! (Compared to previous models)

The new integrated construction method used provides shock resistance of 10,000 m/s² (approx. 1,000 G in X, Y and Z directions for three times each), and vibration resistance clears durability tests of between 10 and 500 Hz (3mm 0.118 in amplitude in X, Y and Z directions for 2 hours each). In addition, resistance to impulse noise is approx. three times greater than for previous models.

Highly resistant to water or oil! IP68g* protective construction

The new integrated construction method used improves environmental resistance performance. The IP68g prevents damage to the sensor by stopping water and oil getting inside.

* For details, refer to the "Specifications" (p.652~)

Sensing presence of metallic objects on a part feeder

Vibration resistance: 500 Hz

FUNCTIONS

Indicators are easy to see over a wide field of view

A prism with a wide field of view has been developed. This has greatly improved the visibility of the operation indicators.

GX-H□

GX-F

MOUNTING

Tightening strength increased with no damage!

A metal sleeve has been inserted. It is possible to tighten up to 0.7 N·m *.

* Maximum tightening torque for M3 screw.

Conductor thickness doubled to make wiring much easier! (GX-8 only)

The conductor's thickness was doubled for the GX-8. This makes it easier to handle and perform crimping work on the cables. In addition, the tensile strength of the crimping area has become higher.

SENSING CHARACTERISTICS (TYPICAL)

GX-8 type

Sensing field Correlation between sensing object size and sensing range

As the sensing object size becomes smaller than the standard size (iron sheet 15 × 15 × t 1 mm (0.591 × 0.591 × t 0.039 in)), the sensing range shortens as shown in the left figures.

GX-12 type

Sensing field Correlation between sensing object size and sensing range

As the sensing object size becomes smaller than the standard size (iron sheet 20 × 20 × t 1 mm (0.787 × 0.787 × t 0.039 in)), the sensing range shortens as shown in the left figure.

PRECAUTIONS FOR PROPER USE

Refer to p.1012~ for general precautions.

• 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-8 type

• 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 flat head screw or a pan head screw.)

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.

Influence of surrounding metal

- When there is a metal near the sensor, keep the minimum

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-8 type: 6mm 0.236 in GX-12 type: 6.5mm 0.256 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.
