Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.

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

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

• 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.

• This unit may be used in the following environments.

  • Indoors (in the environment condition rated in ‘Specifications’)
  • Altitude max. 2,000 m
  • Pollution degree 2
  • Installation category II

Cautions for Installation

• 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.

Operation Timing Chart

Grounding

• The sensing distance is varied by grounding status of the capacity proximity sensor or the target. Check the material when installing the sensor and selecting the target.
• When the capacity proximity sensor and the target are grounded, the electric field is concentrated on the detection surface and the sensing distance may increase.
• If it is not grounded, the electric field radiates to the sensing surface in various directions, and the target is continuously charged with electric charge, the sensing distance may be shorten.

Sensitivity Adjustment

Please turn potention 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 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.
• ( ) is for Normally closed type.

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.

Sold Separately: Protection Cover (P90-M□)

The welding tip (spatter) generated during arc welding has a property of sticking to plastics and metals. If several welding tips are attached to the front or body of the proximity sensor, it may be difficult to replace the body or cause a malfunction.
When using a general type proximity sensor, use a silicone protective cover (sold separately). Only for flush (shield) type.
