KGEA-BFCWX
Emitter Antenna housing plastic base-potted and outside
connector unsealed & sealed.
Characteristics
PKE emitter antennas
103x20x9 mm ( 33 µH – 500 µH )
The antenna KGEA-BFCWX is designed for
emission of a LF field to allow hands free access
towards the Customer Device Identification
for automotive application. This type antenna
is inserted in the vehicle being integrated into
the Access and Start Hand Free subsystem for
requirements Passive Entry and Remote keyless
Go System. Housing plastic base (materials PBT, PA-66 or ABS) assuring extreme conditions
of humidity, liquids, substance and extreme environments. The antenna concept is similar to
KGEA-BFCR series, but smaller in size.
The connector (sealed and unsealed) is optional and it can be customized to required
features. Designed to allow long emitting-reading distances in the smallest volume.
- Ideally used in keyless smart entry system
- Transmitting low frequency LF (20kHz, 125kHz and 134kHz).
- Low tolerances in the resonance frequency LC
- High stability in temperature (-40ºC up to +85ºC).
- Connector located outside assembly housing plastic base (Optional).
- Long reading distances and average current 2-4App.
- Strong anchor points which provide an easy assembly and will ensure mechanical robustness.
- Custom LCR value under demand.
