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.
• 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
