KGEA-HBT Short Range Antenna LF for smart entry system. External housing + LPM (filled)

Short Range Antenna LF for smart entry system. External housing + LPM (filled).

PREMO offers a short antenna with a high mechanical robustness and the best performance electrical on metal surface due to its bridge type design external housing.

Characteristics:

Short antenna (length until 150 mm).
External housing shape H-bridge Material PBT-GF30% or PA66-GF30%.
Strong anchor points which provide an easy assembly and will ensure mechanical robustness.
Higher impact absorption and mechanical reduction preventive.
LF antenna module inside external housing is to cover by Low Pressure Technology (LPM)
LPM is a well know technology in PREMO.
Very fast to produce (No Curing needed)
IP56 grade Waterproof
Connector Non Waterproof IP52 located outside assembly housing plastic base.
High stability in temperature (-40ºC up to +85ºC).
Resonant frequency adjusting below +/- 2kHz.
Custom L-C value (F-Resonant)
This antenna is designed based on AECQ-200
