Safety Considerations

• Observe all ‘Safety Considerations’ for safe and proper operation to avoid hazards.
• symbol indicates caution due to special circumstances in which hazards mayoccu

Warning Failure to follow instructions may result in serious injury or death.

1. Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.)
   Failure to follow this instruction may result in personal injury, economic loss or fire.

2. Do not use the unit in the place where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact, or salinity may be present.
   Failure to follow this instruction may result in explosion or fire.

3. Do not disassemble or modify the unit.
   Failure to follow this instruction may result in fire.

4. Do not connect, repair, or inspect the unit while connected to a power source.
   Failure to follow this instruction may result in fire.

5. Check ‘Connections’ before wiring.
   Failure to follow this instruction may result in fire.

Caution Failure to follow instructions may result in injury or product damage.

1. Use the unit within the rated specifications.
   Failure to follow this instruction may result in fire or product damage.

2. Use a dry cloth to clean the unit, and do not use water or organic solvent.
   Failure to follow this instruction may result in fire.

Cautions during Use

• Install the unit correctly with the usage environment, location, and the designated specifications.
• Do NOT impacts with a hard object or excessive bending of the wire lead-out. It may cause damage the water resistance.
• Do NOT pull the Ø 3.5 mm cable with a tensile strength of 25 N, the Ø 4 mm cable with a tensile strength of 30 N or over and the Ø 5 mm cable with a tensile strength of 50 N or over. It may result in fire due to the broken wire.
• When extending wire, use AWG 22 cable or over within 200 m.

Sensitivity Adjustment

Please turn potation VR to set sensitivity as below procedure.

• When there is distance fluctuation between proximity sensor and the target, please adjust 2 at the farthest distance from this unit.
• Turning potent ion 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.
• ( ) is for Normally closed type.

Stop at ON (OFF) position

| Without a sensing object, turn the potent ion VR to the right and stop at the proximity sensor is ON (OFF).
2|

Stop at OFF (ON) position

| Put the object in right sensing position, turn the potention VR to the left and stop at the proximity sensor is OFF (ON).
3| | If the difference of the number of potention VR rotation between the ON (OFF) point and the OFF (ON) point is more than 1.5 turns, the sensing operation will be stable.
4| | If it is set in sensitivity adjustment position of potent ion VR at center between 1 and 2, sensitivity setting will be completed.

Mutual-interference & Influence by Surrounding Metals
■ Mutual-interference
When plural proximity sensors are mounted in a close row, malfunction of sensor may  be caused due to mutual interference.
Therefore, be sure to provide a minimum distance between the two sensors, as below table.

■ Influence by surrounding metals
When sensors are mounted on metallic panel, it must be prevented sensors from being affected by any metallic object except target. Therefore, be sure to provide a minimum distance as below chart.

Tightening Torque

Use the provided washer to tighten the nuts.
The tightening torque of the nut varies with the distance from the fore-end. [Figure 1] If the nut tip is located at the front of the product, apply the front tightening torque the allowable tightening torque table is for inserting the washer as [Figure 2].
