Mounting Direction for Distance-settable Models

• Make sure that the sensing side of

the Sensor is parallel with the

surface of the sensing objects.

Normally, do not incline the

Sensor towards the sensing

object.

If the sensing object has a glossy

surface, however, incline the Sensor

by 5

° to 10° as shown in the

illustration, provided that the Sensor

is not influenced by background

objects.

• If there is a mirror-like object below the Sensor, the Sensor may not

operate stably. Therefore, incline the Sensor or separate the

Sensor from the mirror-like object as shown below.

• Do not install the Sensor in the wrong direction. Refer to the

following illustration.

Install the Sensor as shown in the following illustration if each sensing

object greatly differs in color or material.

• The stability indicator may turn off in reaction to reflection from

background objects. In such cases, incline the Sensor by 10

° as

shown in the illustration for more stable detection.

Indicator Operation

Note: If the stability indicator is lit, the detection/no detection status is

stable within the rated ambient operating temperature (

−10 to

55

°C).

● Inspection and Maintenance

Cleaning

Never use paint thinners or other organic solvents to clean the surface

of the product.
