Application
- SUS 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. - Achieves an ultra-thin sensor body with a thickness of 4 mm.
Since it is a magnetic shield type, it can be mounted in close contact with the side of the sensor. - 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 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.

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 two or more identical sensors are used, position at least at the spacing shown in the figure on the left to prevent mutual interference.
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-HC41 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.
