The new emitter antenna, the KGEA-BFWX series, has been designed for emission of a LF field to allow hands free access towards the Customer Device Identification for automotive application. These antennas are 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 Polyamide (ABS or PA66 optional) assure extreme conditions of humidity, liquids, substances and extreme environments.

The connector is optional and it can be customized to required features. It can be sealed or unsealed with different numbers of circuits, wire size and located outside the assembly of the antenna with cables type CSA 105ºC. Inside of the housing plastic base the serial inductance, capacitance and resistance can be customized to required values. The antenna has been designed to allow long emitting-reading distances in the smallest volume. Variety of mounting requirements and solutions are possible to accommodate different fastening anchors and mechanical robustness.

Key points:
 

• Transmitting low frequency LF.
• High stability in temperature (-40ºC up to +85ºC).
• Ideally used in keyless smart entry system.
• Connector located outside assembly housing plastic base.
• Low tolerances in the resonance frequency LC.
• 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.
