Application
- Steel material pachinko ball detection.
Features
- The 2-wire sensor requires an external output residual voltage processing circuit and an open collector output conversion circuit (interface IC, etc.).
Since this sensor has these circuits built-in, the cost of the external circuit of the sensor can be significantly reduced. In addition, since this sensor has an open collector output, High / Low logic processing is possible, and it can be directly connected as an input signal of 30 V DC or less. - Ultra-thin type with a thickness of 4 mm.
- Steel material 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 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.

Output Circuit
*Because there is no reverse connection protection diode built-in, pay careful attention to the polarity of the power supply.
Characteristics
- Range of detection
The pachinko ball is inserted from the IN side, and the distance from the detection point to the point where the detection point changes to non-detection is set as the detection range.
- Hysteresis
The pachinko ball is inserted from the IN side, the pachinko ball is moved in the opposite direction to the insertion from the point to be detected, and the distance from the point where the detection is changed to the non-detection is used 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. Otherwise, the range of detection may increase or other malfunctions may occur.
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 steel pachinko balls.
Do not use this sensor as it cannot detect SUS pachinko balls.
Please use model / MD-HC4S1 to detect SUS 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.
