KGEA-BFCR

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 Identication for automotive

application. This type antenna is inserted in the vehicle

being integrated into the Access and Start Hand Free

Nomenclature description

Electrical diagram

145x26x12mm (33 µH - 500 µH)

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.

L: Ferrite core coil inductance

R: Copper resistance and connection

C: Tunning internal capacitor NPO

Rdc: Optional parallel resistor

Z: External impedance
