1、Product Description
Manufactured by Huizhou Antenk Electronics Co., Ltd, the AT2500V series vertical plug-in terminal block with dual 3.5mm and 3.81mm pitch is a compact screw-type wiring connector designed for safe low voltage power and signal circuit connection on printed circuit boards. All manufacturing processes strictly abide by dimensional tolerances and structural requirements specified on official engineering drawings. The insulating housing is composed of PA66 material filled with 23 percent glass fiber, featuring excellent flame retardancy, high temperature resistance and structural stability to adapt to complex electronic working environments. Internal conductive terminals are brass with full tin plating, which effectively reduces contact resistance and prevents surface oxidation for long-term stable conduction. This terminal block is rated for 125V voltage and 8A current, supporting 2 to 16 poles, optional pin lengths and multiple insulator colors to meet diverse layout demands. Our complete production workflow includes independent precision mold development, brass terminal high-speed stamping, tin electroplating, plastic injection molding, automatic component assembly and comprehensive finished product inspection. Advanced imported Japanese and Taiwanese production equipment ensures accurate pitch dimension, and all raw materials fully comply with EU RoHS and REACH environmental regulations.
This vertical pluggable terminal block owns simple and efficient wiring operation steps. Users loosen the built-in locking screws, insert stripped wire cores into the wiring cavities, then tighten screws moderately to firmly fix wires inside the block. Its vertical pin structure can be directly soldered onto PCBs, and the plug-in split design enables quick circuit disassembly, maintenance and replacement. It is widely adopted in industrial control modules, small switching power supplies, household digital appliances, communication equipment, sensors and portable precision electronic instruments. During application, users shall never exceed the rated voltage and current values to avoid terminal overheating and burnout. Excessive screw tightening torque is prohibited to prevent thread sliding and plastic housing cracking. Unused terminal blocks need dry sealed storage to protect tin-plated terminals from oxidation. Most specifications obtain UL certification numbered E472792, and our factory holds ISO9001, ISO14001 and IATF16949 quality system certifications.
Compared with other terminal block manufacturers in the industry, Antenk independently develops and owns more than 250 sets of plastic injection molds and 180 sets of metal stamping molds, supporting customized pole numbers, pin lengths, insulation colors and pitch selection for this dual pitch terminal block series. Our 10000 square meter production base employs 250 skilled workers, equipped with over 180 automatic assembly machines and 20 sets of professional electrical testing instruments, realizing stable mass production and on-time delivery for bulk overseas export orders. As a brand granted Guangdong Famous Trademark certificate, more than 70 percent of our connectors are exported to Europe, America, Southeast Asia and South America worldwide. We accept small batch customized orders without extra mold opening expenses.
We carry out rigorous full-process quality inspection for each batch of plug-in terminal blocks, covering incoming raw material detection, real-time monitoring of stamping, electroplating and injection molding procedures, dielectric voltage withstand testing, screw tightening durability testing and salt spray anti-corrosion testing. Each production batch reserves complete lot traceability records for quality review. Multi-layer strict inspection greatly improves long-term connection stability, anti-vibration and anti-loosening performance, effectively cutting down circuit faults caused by poor contact. We offer free product samples, detailed PCB layout drawings and 24-hour online technical support for all global buyers, establishing long-term sincere cooperative partnerships with electronic manufacturers all over the globe.
Tin Coated Brass Terminals deliver lasting conductive efficiency and superb anti-tarnish performance for PCB wiring connection.
Glass Reinforced PA66 Casings withstand thermal cycling and comply with international flame retardant safety standards.
Two Pitch Circuit Terminals support 3.5mm & 3.81mm pitches to accommodate diversified printed circuit board layouts.
