Model MD-HC4SD Thin 2-wire Through-type Proximity Sensor for SUS Pachinko Balls (Shield Type) NEW 

Application

  • SUS pachinko ball detection.

Features

  • A 2-wire through-type proximity sensor exclusively for steel pachinko balls that can save wiring.
  • Ultra-thin type with a thickness of 4 mm.
  • SUS pachinko balls can be counted even when passing in an unbroken consecutive line.
  • Since the C-cut shape is used for the main body case, it is possible to prevent incorrect installation orientation.
  • A connector with a double contact structure is used. Compared to general connectors, it exhibits strong performance against "vibration" and "adhesion of dust".
  • A transparent cover allows easy check of the internal condition.
  • Features a keyway on the case side for an easy installation in one touch.
  • Combined use with EWD-271 (radio wave sensor) gives greater safety against radio interference.

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.

Characteristics

  • Range of detection
    The detection range is the distance from the point where the output transistor is turned off when the pachinko ball is inserted from the IN side to the point where it is further inserted and the point is changed from the OFF point to the ON point.
    MD-HC4D_201204B_EN-1_03.jpg
  • Hysteresis
    Insert a pachinko ball from the IN side and move it in the opposite direction from the point where the output transistor turns OFF, and use the distance from the OFF point to the ON point as the hysteresis.

Precautions During Use

Influence by Surrounding Metals

Avoid metals in the surroundings, within 3 mm of the detection side and back side of the proximity switch.

Mutual Interference

When using multiple sensors adjacent to each other, use them at intervals greater than the values shown in the figure below to prevent mutual interference.(The different frequency model type has “B” at the end of its model designation.)

Others

  • This sensor is a dedicated detection sensor for SUS pachinko balls.
  • Although this sensor can detect steel pachinko balls, it does not give correct characteristics and should not be used.
  • Please use model / MD-HC4D to detect steel pachinko balls.
  • Be sure to insert and remove the connector horizontally.
    If you insert or remove it at an angle, it may cause terminal deformation, case damage, or poor contact.
For other precautions, refer to "General Precautions" for proximity sensors.
