Application
- Ball count counter
- Medal counter
- Intervening Medal or Ball Dispenser
- Slot machine
- Pachinko machine
- SUS ball detection proximity sensor
Features
- A low cost, open collector output radio frequency wave sensor that is easy to use.
- Since this is a normally closed output, it is easy to identify harness failures.
- You can monitor most of the frequency range of the sensor using any high frequency.
- It is possible to detect exposure to fraudulent emissions, with high sensitivity, from external sources that may interfere with a pachinko machine and its control unit.
- The sensor can be easily recycled for reuse, as it can detect fraudulent emissions in the frequency bands radiated by the high-frequency proximity sensors of all manufacturers.
- It is possible to monitor exposure to fraudulent emissions to the main board.
- The wide band frequency range from 200kHz to 3000kHz used for proximity sensor can be monitored with high sensitivity.
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.

Precautions During Use
Precautions During Use
- A highly sensitive radio frequency wave sensor. Use away from devices that generate high frequency noise.
- When using a power supply with large common mode noise, connect the GND line to FG via a large capacitor.
- If used near a broadcast antenna, common mode noise will be input via 100V AC. Connecting the GND line to the FG line via a capacitor removes common mode noise.
