Mutual-interference and 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 provide a minimum distance between he two sensors with referring to he chart below.

Face to Face Parallel

Influence by surrounding metals

◎

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

Setting Distance

Target

Moving

● Sensing distance can be changed by the shape, size or material of the target.

Check he sensing distance like (a), then pass the target within range of setting distance (Sa).

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

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]

E.g.) PRACM30-10DN

Setting distance (Sa) = 10mm × 0.7 = 7mm

Caution During Use

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

2. 12-24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.

3. Use the product, after 0.8 sec of supplying power.

4. 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.

5. If the surface of the product is rubbed with a hard object, PTFE coating can be worn out.

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