KYOCERA AVX 9155-020 Series 1.27mm fine-pitch, board-to-board battery connectors are suitable for medical, industrial and networking applications. Devices feature ultra-robust and -reliable gold-plated beryllium copper (BeCu) contacts proven to establish and maintain high-integrity electrical connections in harsh application environments with operating temperatures extending from -40°C to +125°C for up to 15,000 mating cycles. Devices feature low-profile, UL94 V-0 flame retardant, glass-filled liquid crystal polymer (LCP) insulators that measure just 2.35mm high, have a nominal working height of 2.5–3.1mm, and are end-to-end stackable for broad configuration and application suitability. Products are currently available in two-, three-, four-, and five-way variants with a nominal force working range spanning 0.30–0.55N, a minimum of 0.8μm ductile nickel underplate, a minimum of 0.75μm hard gold in the contact area, and 1.5–3.0μm lead-free matte tin on the tails. Two- and three-way variants are rated for a full 3A per contact, while four- and five-way variants are rated for 2A per contact, and all four immediately available part numbers are rated for 400Vac.
