Model MDS-H12R Pachinko ball (Steel balls) Reversible Detection Proximity Sensor (Counter Sensor)

Application

  • Counting in steel pachinko ball dispensers or counting bills (currency).

Features

  • Can accurately count up and down the number of steel pachinko balls coming continuously.
  • The count remains accurate even when steel pachinko balls passing or remaining inside the sensor vibrate or move in the opposite direction.
  • An infinite number of sensors can be installed together making it possible to count lots of balls in a short time.
  • Three types with different frequencies are available to prevent interference in multiple-sensor installations.

International Standards

  • Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
  • Products is compliant to the RoHS directive.

* Please consult about "change of specification" and "request of specification" of the product.

Usage precautions

Influence of surrounding metal

When installing metal around the proximity sensor, leave space as shown in the figure below. However, metal cannot be installed in all directions, but in one direction only. Contact is possible in case of steel pachinko balls.
*The detection range varies by ±10% or less when metal is 1.2 mm in thickness, has an area larger than the part surface, and is separated by 5 mm or more from each side.

Mutual interference

If you install two or more sensors in series, separate them at least by the distances shown in the figure below to prevent reciprocal interference. If you install two or more sensors laterally, use standard products and products with a different frequency alternately to prevent interference. Moreover, separate them at least by the distances shown in the figure below.

Precautions During Use

  • Ensure to use the sensor after thorough prior evaluations including the operation check, performance check, and reliability check with the sensor incorporated in your product.
  • Be sure to contact us first if the product is being considered for use in an application which requires extremely high reliability, where its breakage, malfunction, or operation can be reasonably expected to be, directly or indirectly, a significant threat to human life, or can cause injury, or damage to property, including, but not limited to medical equipment, automobiles, aerospace vehicle instruments, nuclear power control equipment or other equipment or instruments. In normal use, be sure to provide safety measures to avoid secondary disasters to ensure the safe operation of the entire system.
  • Avoid use and/or storage of the product in a place where it can be exposed to the following; chemical solutions and corrosive gas; abrupt temperature changes; direct sunlight; vibration or shock. Dew condensation or freezing may affect the product performance.

Other

  • Please note that this proximity sensor can detect steel pachinko balls, but not SUS pachinko balls.
    Contact us for detection of SUS pachinko balls.
  • See proximity sensor general usage precautions for other precautions.
