KGEA-BFCR_14 Datasheet, PDF (1/1 Pages) PREMO CORPORATION S.L – Emitter antenna housing plastic base with resin and outside connector unsealed & sealed

KGEA-BFCR
145x26x12mm (33 µH - 500 µH)
Emitter antenna housing plastic base with resin and
outside connector unsealed & sealed
Characteristics:
The antenna KGEA-BFCR is designed for emission
of a LF eld to allow hands free access towards
the Customer Device Identi cation 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 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 4-8App.
- Strong anchor points which provide an easy assembly and will ensure mechanical
robustness.
- Custom LCR value under demand.
