Product details

Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001 and ISO14001 certified manufacturer founded in 2004 with over 250 employees and a 10,000m² facility in Shenzhen and Dongguan, proudly presents the Cell Battery Contacts Model 5230 – a low‑profile, three‑finger elastic retention contact specifically engineered for 16mm to 24mm diameter coin cell batteries (CR1616, CR1620, CR2032, CR2450, etc.). Unlike conventional stamped dimple contacts that rely on a single point of connection, Model 5230 features three independent spring fingers arranged in a triangular pattern, delivering a balanced normal force of 25–35g per finger (75–105g total) for superior shock and vibration resistance. Manufactured on our 11 Japanese/Taiwanese high‑speed stamping presses using premium phosphor bronze (C5191) with selective gold plating (0.4μm) on all three contact tips, this terminal achieves ultra‑low contact resistance below 25 milliohms and outstanding corrosion resistance. Key characteristics include an ultra‑low installed height of just 1.8mm above PCB, support for continuous currents up to 300mA (pulse 1A), reliable operation from -40°C to +85°C, and integrated polarity key to prevent reverse insertion. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated optical inspection.

Application Scope: Model 5230 is ideal for compact, high‑reliability devices where battery dislodgement cannot be tolerated, including portable medical devices (digital thermometers, pulse oximeters), automotive key fobs, active RFID tags, wireless IoT sensors, wearable fitness trackers, smart watches, real‑time clock backup on PC motherboards, electronic shelf labels, and industrial handheld terminals – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the three SMT anchor pads to the PCB using standard reflow soldering (recommended temperature profile: 245–260°C peak). Insert the coin cell positive (+) side facing the three‑finger contact by sliding horizontally or pressing vertically – a tactile click confirms full seating. For removal, use a plastic pry tool under the battery edge. Precautions: Do not exceed 300mA continuous current; avoid touching gold‑plated fingers with bare fingers; ensure PCB pads match the recommended land pattern; operate within -40°C to +85°C range. Advantages Over Competitors: Unlike competitors who use single or dual‑beam designs that allow battery rotation or partial dislodgement under shock, Antenk’s three‑finger triangular pattern locks the battery in all directions – passing 15G vibration and 50G shock tests. Competitors often use tin or nickel plating that oxidizes, raising contact resistance above 100 milliohms after 12 months; Antenk’s selective gold (0.4μm) ensures <25 milliohms for the product lifetime. While others require 10,000+ MOQ and $1,000+ tooling fees for multi‑finger designs, Antenk offers low MOQs (1,000 units) with no tooling fees for standard configurations. Our IATF16949 certification ensures automotive‑grade quality management. Additionally, our 72‑hour salt spray testing and 20,000‑cycle insertion/removal validation guarantee unmatched reliability.

Antenk’s vertical integration delivers consistent quality for Model 5230. Process flow: (1) In‑house mold design using our 180+ precision terminal molds (dedicated progressive tooling with 22 stations for three independent fingers); (2) High‑speed stamping on Japanese/Taiwanese presses (11 machines) using 0.12mm phosphor bronze strip – the three‑finger geometry requires ultra‑fine die clearance of 0.01mm; (3) Selective barrel plating: nickel underplate (2μm) + gold on all three finger tips (0.4μm) using precision masking; (4) 100% AOI dimensional inspection with critical tolerance of ±0.02mm on finger height and spacing; (5) Individual spring force testing per EIA-364-04 for each finger (25–35g each); (6) Contact resistance testing per EIA-364-06 using gold‑plated battery simulator; (7) 72‑hour salt spray corrosion testing; (8) Automated assembly on 180+ machines with gold thickness verification via XRF; (9) Final QC with lot traceability and full dimensional report including finger coplanarity. Our laboratory houses 20+ testing devices including profile projectors, XRF, environmental chambers, and automated vibration/shock tables. With 250+ employees, 18+ mold‑making machines, and 250+ plastic injection molds, we provide free samples, complete 2D/3D CAD drawings showing three‑finger geometry and recommended PCB land pattern, and 24‑hour technical support. Contact Antenk today for a quotation – we typically respond within 4 hours and ship Model 5230 samples within 3 days. Ask about our volume discounts (5,000+ units) and custom options (finger force adjustment, alternative gold thickness, or beryllium copper for extreme temperatures). With 70% of our products exported worldwide and 18 years of experience, Antenk is your trusted partner for high‑reliability cell battery contacts that eliminate intermittent power failures.
