Product details

Huizhou Antenk Electronics Co., Ltd. manufactures SF-S7091-42R-X-23 series 2.7 SMT shield fingers designed for reliable PCB EMI shielding and grounding connection, featuring recommended 2.30mm minimum working height and 1.2N minimum contact force with stable elastic compression performance, mechanical durability up to 2000 plug and unplug cycles to sustain long-term grounding continuity. This shielding spring contact adopts 0.10mm thick titanium copper as raw material, full 30 microinch minimum nickel underlayer plating with 0.8u gold plating on contact surface and tin plating on soldering area, passing 24-hour salt spray anti-corrosion test, electrically rated for maximum 6A working current and steadily operating from minus 55 degree Celsius to plus 125 degree Celsius, fully compliant with HSF lead-free and RoHS environmental standards, two packaging options bag and tape & reel adapt automatic SMT pick and place assembly lines with 2600 pieces per reel standard loading quantity. This compact SMT shield finger is widely applied in liquid crystal display modules, digital cameras, communication modules, industrial control panels, portable storage equipment, digital household appliances, electronic toys, computer peripherals, automotive electronic assemblies and precision measuring instruments that need effective electromagnetic interference suppression and stable grounding circuit connection. Operators should reserve enough compression space following official PCB layout drawing, avoid over-compression to prevent titanium copper spring fatigue and permanent deformation, and store finished shield fingers in dry sealed packages to stop gold and tin plating layer oxidation. Unlike competitors outsourcing metal stamping and electroplating Antenk carries out complete independent production workflow covering self-designed precision metal mold fabrication, high-speed titanium copper terminal stamping, multi-layer nickel gold tin electroplating and full salt spray high-low temperature cycle reliability laboratory testing, holding ISO9001 ISO14001 IATF16949 and UL E472792 certifications while conforming to REACH global environmental regulations. We own more than two hundred fifty proprietary plastic connector molds and one hundred eighty metal terminal molds, provide customizable material thickness plating thickness packaging modes and dimensional sizes, deliver round-the-clock professional engineering technical support, and over seventy percent of our shielding contact products are exported worldwide relying on our Guangdong Famous Trademark ANTENK and consistent stable mass production quality.

0.10mm Titanium Copper Shield Finger delivers outstanding elasticity and fatigue resistance for long-term PCB EMI shielding use.

Gold Plated EMI Ground Spring Contact ensures low impedance grounding and reliable anti-interference performance on circuit boards.

2.3mm Min Working Shield Finger maintains stable 1.2N contact force under standard assembly compression height.
