KGEA-BFCAM
85x16.8x7 mm ( 33 µH – 500 µH)
Keyless Go Emitter Antenna Low Pro le Potted Unsealed &
Sealed Connector
Characteristics
This is a new low pro le antenna specially designed to assembly in the aftermarket
operation.
Antenna concept is similar to those KGEA-BFC series, but smaller in size (ferrite + capacitor
in a box potted) and easy to joint to anywhere by a simple adhesive tape.
These kind of antennas provide a cable with a customized length without connector in its
standard version (connector can be assembly under demand).
Several combinations of inductance and capacitor values are offered as standard versions.
Any other combination can be provided, together with the possibility of fully customized
design, depending mainly of capacitor size available.
Ideally used access and start Hand Free subsystem for Passive Entry keyless Go System
Requirements for automotive application.
- Low pro le size.
- Low tolerances in the resonance frequency LC
- High stability in temperature (-40ºC up to +85ºC).
- Transmitting low frequency LF (20kHz, 125kHz and 134kHz).
- Long reading distances and average current 2-4App.
- Custom LCR value under demand.
