Fabric-Over-Foam Gasket

Fabric-Over-Foam Gasket

  • Fabric-over-foam-Gasket
  • Fabric-over-foam-Gasket

Overview

  • Fabric-over-foam gasket, a type of EMI Shielding Gasket, is made of conductive fiber or metal foil for its cladding, allowing EMI/RFI shielding and electrical surge grounding effects to be functioned at the same time.
  • Double-sided taping for easy attachment to objects and can be manufactured in various shapes/sizes as required.
  • Good for touch sensor gasket or touch switch gasket

Features

  • RoHS Compliant, Halogen Free
  • Flame retardant material (UL94V-0) used
  • EMI shielding and electrical surge grounding function at the same time
  • Excellent elasticity using PU sponge for core material
  • Various lengths and shapes are available according to the application, and easy to die-cut or scissor cutting

  • Fabric-over-foam-Gasket-in-LCD-Display
  • Fabric-over-foam-Gasket-Roll

Touch Sensor Gasket / Touch Switch Gasket

  • Touch sensor gasket (touch switch gasket) functions as an electrode connecting display panel and PCB in the electrostatic touch input method, and is mainly suitable for touch switches of home appliances and industrial devices.
  • Hole processing in the center is possible, so it can be attached over LED light to show ON/OFF status when touched.
  • Touch grid method is expensive, but foam gasket has a good workability and economic advantages when the number of touch points is appropriate.
  • This gasket does not stress PCB/Panel thanks to its softness and elasticity.
