Mutual-interference & Inuence by Surrounding Metals

Mutual-interference

When several proximity sensors are mounted closely, malfunction of sensor may be caused due to mutual interference.
Therefore, be sure to keep a minimum distance between the two sensors, as below charts.

A

Inuence by surrounding metals

When sensors are mounted on metallic panel, it is required to protect the sensors from malfunction by any metallic object.
Therefore, be sure to keep a minimum distance as below chart.

Setting Distance

Moving

direction

● Sensing distance can be changed by the shape, size or material of the target. Therefore please check the sensing distance as (a),

then pass the target wi hin range of setting distance(Sa) as (b).

● Setting distance(Sa) = Sensing distance(Sn)×70%

E.g.)PR30-10AO

Set ing distance(Sa) = 10mm×0.7=7mm

Installation and Tightening Torque



When tightening the nut, use the provided washer as [Figure 1]
When installing the product, the tightening torque of the nut varies
according to the distance from the fore-end.
The front part of the product is from the fore-end to the dimension on
the below table, and the rear part is from the tip of the nut to the end
of the product. [Figure 2]
In case the nut is placed in the front part of the product, apply
tightening torque for front part.
[Table 1] the allowable tightening torque table is for inserting the
washer as [Figure 3].

[Figure 1]

Caution during Use



1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.

2. Wire as short as possible and keep away from high voltage lines or power lines, to prevent surge and inductive noise.
Do not use near the equipment which generates strong magnetic force or high frequency noise (transceiver, etc.).
In case installing the product near the equipment which generates strong surge (motor, welding machine, etc.), use diode or varistor to remove
surge.

3. Do not connect capacity load to the output terminal directly.

4. This unit may be used in the following environments.

Indoors (in the environment condition rated in 'Specications')
