Rectangular inductive proximity sensors

Industry’s no. 1* in stable sensing. This sensor has the longest stable sensing range among comparable rectangular inductive proximity sensors in the industry.
The sensor is easy to install. Precise adjustment and control of sensing sensitivity greatly reduces individual sensor differences and variations.

Now it is much easier to adjust sensor positions when using multiple sensors or when sensors have been replaced. The product, e.g. the coil and core has been completely redesigned to provide excellent temperature characteristics. Stable sensing can be obtained regardless of the time of day or season.

Characteristics:

  • Built-in amplifier
  • Mutual interference prevention
  • Oil and water resistant
  • Easy to see indicators

Notes:

  1. Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23°C.
  2. “I” in the model No. indicates a different frequency type.
  3. The maximum operation distance stands for the maximum distance for which the sensor can detect the standard sensing object. The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient temperature drift and/or supply voltage fluctuation.
  4. Panasonic Industrial Devices SUNX’s IP68 test method
    (1)Immerse at 0m below 0℃ water surface and leave for 30 min. Then, immerse at 0m below +70°C water surface and leave for 30 min.
    (2) Regard the heat shock test in (1) as one cycle and perform 20 cycles.
    (3) Leave in water at a depth of 1m in water for 500 hours.
    (4) After tests (1) to (3) , insulation resistance, voltage withstandability, current consumption, and sensing ranges must meet the standard values.
  5. If using the sensor in an environment where cutting oil droplets splatter, the sensor may deteriorate due to added substances in the oil. Please check the resistivity of the sensor against the cutting oil you are using beforehand.
  6. This is the numerical value when the sensor is mounted onto an insulant plate. When the sensor is mounted onto a steel or stainless steel plate, insert the optional aluminum sheet between the sensor and the plate.
  7. This is the numerical value when the sensor is mounted onto an insulant plate. When the sensor is mounted onto a metallic plate, the maximum response frequency will decrease.
