Application Scope: Model 5252 is ideal for devices requiring dual-battery power with minimal PCB space, including portable medical monitors (dual AA for extended runtime), wireless keyboards and mice, children's electronic toys, digital cameras with battery grips, portable flashlights (dual C/D for high brightness), industrial sensors, backup alarm systems, portable PA systems, GPS tracking devices, and IoT gateways – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the contact's dual reinforced tails (4 solder points) via through-hole to the PCB. For series configuration (increased voltage), insert first battery negative against one spring and second battery positive against the other spring. For parallel configuration (extended runtime), ensure both batteries face the same direction. The integrated carrier includes clear polarity markings (+/-). Precautions: Do not mix different battery types or charge levels; do not exceed 10A in parallel configuration; verify series vs. parallel circuit design before soldering; operate within -40°C to +100°C range. Advantages Over Competitors: Unlike competitors who sell two separate contacts requiring manual alignment (leading to misalignment, tombstoning, and field failures), Antenk’s Model 5252 is an integrated solution that guarantees precise spacing and reduces assembly time by 60%. Competitors often use thinner 0.20mm material for dual contacts; Antenk uses heavy-duty 0.30mm–0.40mm phosphor bronze based on battery size. While others require 15,000+ MOQ and1,000–2,500 tooling fees for integrated dual tooling, Antenk offers low MOQs (1,000 units) with no tooling fees for standard spacing/modifications. Our IATF16949 certification ensures automotive-grade quality management – most dual contact suppliers lack this. Additionally, our 72-hour salt spray testing and 15,000-cycle validation ensure superior reliability. The integrated design also eliminates a common failure mode: one battery losing connection while the other remains engaged.
Antenk’s vertical integration delivers consistent quality for Model 5252. Process flow: (1) In-house mold design and fabrication using our 180+ precision terminal molds (dedicated dual-contact progressive tooling with 18+ stations); (2) High-speed stamping on Japanese/Taiwanese presses (11 machines) using 0.30mm–0.40mm phosphor bronze strip – the dual design requires precise carrier strip management; (3) Barrel plating (nickel/tin/gold) with real-time thickness monitoring – uniform coating across both contacts essential; (4) 100% AOI dimensional inspection with critical tolerance of ±0.08mm on each contact position and ±0.10mm on center-to-center spacing; (5) Independent spring force testing per EIA-364-04 for each contact point (both must pass); (6) Contact resistance testing per EIA-364-06 across both contacts simultaneously; (7) 72-hour salt spray corrosion testing; (8) Automated assembly on 180+ machines with polarity verification and carrier strip removal; (9) Final QC with lot traceability and full dimensional report including spacing measurements. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, environmental chambers, and dual-channel contact resistance testers. With 250+ employees including dedicated engineering and QA teams, 18+ mold-making machines, and 250+ plastic injection molds, we provide free samples, complete 2D/3D CAD drawings showing precise dual-contact spacing, and 24-hour technical support.
