About Dongguan City Aosi Electronics.,ltd - Electric Terminals Supplier in United States

Based in the United States, Dongguan City Aosi Electronics.,ltd lists six active product lines focused on electric terminals and electric connectors. The catalogue comprises a 5.00 mm pitch spring clamp terminal block, PCB‑mount pluggable terminal blocks, plug‑in electrical connectors, the DG211V 2.5 mm spring‑type PCB terminal block, PCB screw terminal block connectors, and a pluggable male‑female connector terminal block. All items belong to the electrical apparatus category typically classified under HS chapters 85 (8536‑8537). The supplier’s product count of six reflects a narrow but specific offering within the terminal‑block market.

The listed products target applications such as industrial control panels, power distribution units, and automation equipment where reliable point‑to‑point wiring is required. Each item is designed for PCB mounting or panel installation and uses copper or copper‑alloy conductors with tin or nickel plating to meet standard conductivity and corrosion resistance. The range covers common pitches of 2.5 mm and 5.00 mm, allowing compatibility with standard wire gauges from 22 AWG to 18 AWG. No additional product categories are indicated beyond the six terminal‑block types.

Product Range and Specialties of Dongguan City Aosi Electronics.,ltd

The current catalogue offers terminal blocks that are typical of the IEC 60984 series, with current ratings generally from 2 A up to 10 A and voltage ratings up to 250 V AC. Pitch options of 2.5 mm and 5.00 mm match the widely used DIN rail and PCB standards, while the spring‑type designs provide quick insertion and reliable clamping without tools. Materials commonly specified for these products include copper alloy conductors, tin‑plated or nickel‑plated contacts, and a polymer housing that meets UL 94 V‑0 flame‑retardant criteria.

In the broader industry, electric connectors of this type are often supplied in anti‑static bags or sealed cardboard cartons, with unit quantities ranging from 100 pcs to 10 000 pcs per container. Buyers frequently request datasheets that list contact resistance (< 5 mΩ), insertion force (≈ 2 N), and mechanical durability (≥ 5000 cycles).

Trade and Export Information - Dongguan City Aosi Electronics.,ltd

United States manufacturers of electric terminals typically ship to North America, Europe, and Southeast Asian markets where automation, renewable‑energy, and building‑automation sectors drive demand. The products fall under HS code 8536 (“Electrical apparatus for switching or protecting electrical circuits”) and are subject to standard export documentation such as commercial invoice, packing list, and certificate of origin. Common buyer requirements include UL, CE, and RoHS compliance, which are usually verified through test reports before shipment.

Logistically, terminal blocks are compact; a standard 40‑ft container can accommodate up to 20 000 units depending on packaging density. Exporters often use FOB or CIF terms, and the goods are packed in moisture‑controlled, anti‑static containers to preserve electrical performance during transit. Trade finance for such high‑value electronic components frequently involves letters of credit aligned with Incoterm CIF to major ports such as Rotterdam, Hamburg, and Singapore.

Sourcing from Dongguan City Aosi Electronics.,ltd - Buyer Guidance

Prospective buyers should request the product datasheet that details current rating, voltage rating, pitch, material composition, and compliance certifications (UL, CE, RoHS). A sample batch of 100 units is standard for functional testing, and buyers normally verify contact resistance, dielectric strength, and mechanical endurance against IEC 60984 specifications before confirming larger orders.

Verification of certifications can be done by asking for the latest test reports and a copy of the supplier’s declaration of conformity. Typical minimum order quantities for these terminal blocks range from 500 pcs to 1 000 pcs, with lead times of 2 to 4 weeks after order confirmation, subject to production scheduling and any required pre‑shipment inspections.
