● Please turn poten ion VR to set sensi ivity as below procedure.

①

Without a sensing object, turn the potention VR to the right and stop at the proximity sensor is ON (OFF).

Stop at ON (OFF) position

③

If the difference of the number of potention VR rota ion between the ON (OFF) point and the OFF (ON) point is more than 1.5 turns, the sensing operation will be stable.

※

When here is distance fluctua ion between proximity sensor and he target, please adjust ② at the far hest distance from this unit.

※

Turning potention VR toward clockwise, it will be max., or turning toward counter clockwise, it will be min. The number of adjustment should be 15±3 revolution and if it is turned to the right or left excessively, it will not stop, but it idles without breakdown.

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.

Influence 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 charts.

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].

Cautions 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. Do not connect capacity load to he output terminal directly.

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