Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001:2015 and ISO14001:2015 certified high‑tech enterprise founded in 2007 with over 300 employees and a 10,000m² Huizhou facility, proudly presents the SINGLE 1/2 AA BATTERY HOLDER THM. This precision through‑hole holder is specifically designed for 1/2 AA lithium or alkaline cells (14mm diameter × 25mm length) – a compact power source critical for long‑life, low‑power industrial and medical devices. The holder features a glass‑filled nylon 6/6 housing (UL94‑V0, heat deflection temperature 240°C) with integrated polarity ribs and a reinforced dual‑point positive contact paired with a captive nickel‑plated coil spring on the negative side. Both contacts are stamped from 0.25mm phosphor bronze on our 9 Japanese/Taiwanese high‑speed presses. Key characteristics include contact resistance below 20 milliohms, retention force of 130–170g, continuous current rating of 2.5A, and an operating temperature range of -40°C to +105°C. The four solder tails (2.54mm pitch) are designed for wave or hand soldering, and molded standoffs allow thorough PCB washing. The product is RoHS, REACH compliant and UL recognized (E472792).
Application Scope: The 1/2 AA THM holder is ideal for industrial wireless sensors, IoT end nodes, utility meters (gas/water/electricity), portable medical monitors (glucose meters, insulin pumps), active RFID tags, GPS tracking beacons, memory backup circuits, and emergency call systems – markets where Antenk already serves customers including Flextronics, Foxconn, and Fortune 500 companies across the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the four tails through PCB holes (1.0mm diameter recommended) using wave soldering (260°C peak) or hand soldering. Clip excess leads. Insert the 1/2 AA battery with the positive (+) end against the dual‑beam contact and the negative end against the coil spring – an audible click confirms full seating. The housing’s polarity key prevents reverse insertion. To remove, use a non‑conductive tool to depress the spring. Precautions: Do not exceed 2.5A continuous current; avoid soldering >270°C for >5 seconds; do not use with batteries longer than 26mm; operate within -40°C to +105°C. Advantages Over Competitors: Unlike competitors using ABS housings that crack under thermal cycling or vibration, Antenk uses glass‑filled nylon 6/6, which withstands 240°C and passes 15G vibration tests. Competitors often rely on single‑point positive contacts that lose continuity under shock; our dual‑beam design provides redundant contact paths. While others require 10,000+ MOQ for 1/2 AA tooling, Antenk offers low MOQs (1,000 units) with no tooling fees for standard configurations. Our IATF16949 certification ensures automotive‑grade quality, and our in‑house 40+ lab test devices (including environmental chambers, profile projectors, and salt spray testers) guarantee every batch meets EIA‑364 standards.
Antenk’s vertical integration delivers consistent quality for the 1/2 AA THM holder. Process flow: (1) In‑house mold design using our 380+ plastic injection molds (dedicated 1/2 AA cavity with ±0.02mm tolerance on battery cavity); (2) Injection molding on 10 Japanese/Taiwanese 35‑120 ton machines using glass‑filled nylon 6/6 (melt 270°C, mold 85°C, cycle time 18 seconds); (3) High‑speed stamping of positive dual‑beam and negative spring contacts on 9 Japanese/Taiwanese presses using 0.25mm phosphor bronze strip; (4) Barrel plating: nickel (3μm) + optional gold (0.3μm) for medical versions; (5) Automated spring coiling on Japanese CNC coilers (±0.08mm pitch control); (6) Semi‑automatic assembly: heat‑staking of positive contact, spring insertion, 100% pull‑test (≥5kgf); (7) 100% coplanarity and contact position inspection using automated vision systems; (8) Spring force testing per EIA-364-04 (130–170g); (9) Contact resistance testing per EIA-364-06 (<20 milliohms); (10) 48‑hour salt spray corrosion testing (sample‑based); (11) Final QC with lot traceability. Our laboratory houses 40+ testing devices including XRF for plating thickness, environmental chambers, and tensile testers. With 300+ employees, 18+ mold‑making machines, and 180+ automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings with recommended PCB footprint, and 24‑hour technical support.
