Model EWD-271 High-frequency Induced Magnetic Field Detector (Radio Wave Sensor)

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.

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

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.
