## **Ten times greater bending durability** (Compared with conventional models) **GX-□-R** 

The non-shielded type ( **GX-8ML□** ) has twice the sensing range of the shielded type ( **GX-8M□** ), although having the same size. Hence, it allows margin against sensing distance variations. 

The bending durability of the cable to repeated bending has been increased tenfold by using special alloy cores for the cable.

LASER SENSORS **Flexible cable type** 

Flexible cable type is also available for shielded type. When ordering this type, suffix “ **-R** ” to the model No. (e.g.) Flexible cable type of **GX-3S** is “ **GX-3S-R** ”. 

## **5 m 16.404 ft cable length type** 

5 m 16.404 ft cable length type (standard: 3 m 9.843 ft) is also available. (excluding **GX-4SB** ) When ordering this type, suffix “ **-C5** ” to the model No. 

(e.g.) 5 m 16.404 ft cable length type of **GX-3S** is “ **GX-3S-C5** ”. 

Refer to table below for 5 m 16.404 ft cable length type of flexible cable type sensor.

## **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** 

- The tightening torque should be as given below. 

## **Mounting with set screw** 

## **<Shielded of threaded type>** 

- Tighten the set screw on the flat surface of the sensor without applying excessive force. Make sure to use a set screw with a cup-point end.

Note: Mount such that the nuts do not protrude from the threaded portion. 

- The root truncation of the threads with **GX-8M** □ and **GX-8ML** □ is shallow owing to strengthening of the sensors against tightening. When tapping holes on equipment to fix the sensors, the prepared holes must be ø7.2 mm ø0.283 in or more ~~.~~

Note: The protrusion should be kept C (mm in) or more to avoid reduction of sensing range. 

- To fasten **GX-3S** □ and **GX-4S** □, use a M3 or less set screw and tighten it from a direction perpendicular to the operation indicator.

**GX-F/H GXL GL GX-M GX-U/GX-FU/ GX-N GX** 

## **PRECAUTIONS FOR PROPER USE** 

## **Distance from surrounding metal** 

- As metal around the sensor may affect the sensing performance, pay attention to the following points. 

## **Influence of surrounding metal** 

- The surrounding metal will affect the sensing performance. Keep the minimum distance specified in the table below. 

**==> picture [230 x 115] intentionally omitted <==**

## **Embedding of the sensor in metal** 

- Sensing range may decrease if the sensor is completely embedded in metal. Especially for the non-threaded type and the non-shielded type, keep the minimum distance specified in the table below.

## **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.

## **Others** 

- Do not use during the initial transient time (10 ms) after the power supply is switched on. 

- Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint. 

- **GX-3S** □, **GX-4S** □ and **GX-5M** □ do not incorporate a short-circuit protection circuit at the output. Do not connect them directly to a power supply or a capacitive load. 

## **Mutual interference** 

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