Characteristics

DHSL Door Handle LF Tx antenna for Keyless Entry System (SWITCH and LED).

PREMO is developing customized door handle antennas using a type of technology over-molding low pressure depending on themechanical requirements and waterproof IP degree required by the customer.

For Door Handle Antennas, we also have the ability to integrate in a unique connector (6ways), the Antenna LF + Switch + LED as a single whole.


Characteristics

  • Overmolded Antenna with Low Pressure Technology (LPM)
  • LPM is a well know technology PREMP
  • Very fast to produce (No Curing needed)
  • Low Profile. Height max= 7,2 mm.
  • IP56 grade Waterproof.
  • Connector located outside assembly Antenna LF, Switch and LED.
  • High stability in temperature (-40ºC up to +85ºC).
  • Resonant frequency adjusting below +/- 2kHz.
  • Custom L-C value @ F-Res
  • This antenna is designed based on AECQ-200
