France is home to a thriving consumer electronics and IoT ecosystem, with a medical devices market valued at approximately €16 billion in 2024 and projected to grow at 3.8% annually through 2029. Behind every smart meter, remote control, and connected sensor lies a critical component: the battery contact shrapnel. These small stamped parts ensure stable power transmission from coin cells and cylindrical batteries to circuit boards—and their reliability directly impacts device performance.
CR2032 and Coin Cell Contacts for PCB-Mounted Battery Holders
PCB-mounted battery holders are ubiquitous in French-designed industrial controls, smart meters, and consumer electronics. The CR2032 battery contact shrapnel must provide consistent contact force (1.0-2.0N) while accommodating slight variations in battery thickness. Our phosphor bronze C5191 contacts feature a dimple design on the positive terminal for reliable contact and a resilient negative arm that self-adapts to different battery heights. Nickel plating ensures solderability and oxidation resistance for reflow soldering processes.
Why Material Selection Matters
Phosphor bronze C5191 offers an optimal balance of conductivity (≥15% IACS), formability, and fatigue resistance—essential for contacts that undergo repeated battery replacement cycles. For higher-cycle applications, C5210 provides superior spring memory. Our progressive die stamping process maintains dimensional consistency within ±0.02mm, ensuring every contact fits precisely into the battery holder.
Tape-and-Reel Packaging for SMT Assembly
French electronics manufacturers increasingly rely on automated SMT assembly lines. Our battery contacts are available in tape-and-reel packaging, compatible with pick-and-place equipment, reducing manual handling and improving assembly efficiency.
Custom Designs for Non-Standard Applications
Off-the-shelf contacts rarely meet the exact footprint, force, or plating requirements of custom PCB layouts. We specialize in non-standard battery contact designs, from CR1220 to CR2032, with volumes as low as 500 pieces. Full material certifications and dimensional reports accompany every shipment.
