1、Product Description
Manufactured by Huizhou Antenk Electronics Co., Ltd, the AT2500F series plug-in terminal block with dual 7.5mm and 7.62mm pitch options is a detachable screw-type wiring connector dedicated to stable PCB and equipment internal electrical interconnection. Produced strictly following engineering drawing dimensional standards, this terminal block supports 2 to 24 poles and multiple optional insulator colors for circuit classification. Its housing is crafted from PA66 material filled with 23 percent glass fiber, certified UL94V-0 flame retardant, delivering outstanding structural rigidity and high temperature resistance during soldering and long-term operation. Conductive terminals are nickel-plated phosphor bronze, paired with nickel-plated brass wire cages and zinc-plated M2.5 steel screws, rated for 300V voltage and 12A current, suitable for 18 to 12AWG wires up to 2.5mm² cross-section with a standard tightening torque of 0.4N.m. Our complete standardized production procedure covers in-house mold development, high-temperature injection molding, precision terminal stamping, multi-layer metal electroplating, automatic assembly and full dimensional inspection. Imported Japanese and Taiwanese production machines
guarantee consistent pitch precision and stable clamping force in mass production. All raw materials comply with EU RoHS and REACH environmental regulations to restrict hazardous substances.
Users operate this plug-in terminal block by loosening built-in screws, inserting stripped wire conductors into wiring cavities, tightening screws at 0.4N.m torque to fix wires securely, then plugging the entire terminal module into the matched PCB base to form detachable power and signal circuits. It is extensively used in industrial control cabinets, switching power supplies, household electrical control modules, communication power distribution equipment and precision laboratory instruments. During daily use, operators shall not exceed the rated 12A current to avoid thermal overload damage. Over-tightening screws is forbidden to prevent plastic housing cracking and thread sliding. Unused terminal blocks should be stored in dry sealed surroundings to prevent nickel plating oxidation. Most product specifications obtain UL certification numbered E472792, and our factory holds ISO9001, ISO14001 and IATF16949 certifications, ensuring reliable performance for industrial and automotive electronic applications.
Compared with other terminal block suppliers in the industry, Antenk independently develops and owns over 250 sets of plastic injection molds and 180 sets of metal stamping molds, enabling customized adjustment of pole numbers, housing colors, plating layers and structural details for this dual pitch terminal block series. Our 10000-square-meter manufacturing plant with 250 professional staff is equipped with more than 180 automatic assembly devices and 20 sets of professional testing instruments, ensuring steady batch quality and on-time shipment for large overseas export orders. As a Guangdong Famous Trademark holder, more than 70 percent of our connectors and terminal blocks are exported to global markets. We adopt full-process quality control including raw material incoming inspection, in-process stamping and plating monitoring, voltage withstand testing and clamping force sampling inspection. Strict quality control effectively enhances long-term connection stability and anti-vibration performance, eliminates circuit hidden dangers caused by loose wiring, and builds long-term reliable cooperative relations with electronic manufacturers across Europe, America, Southeast Asia and other global regions.
Nickel Plated Terminal Clamps ensure stable conductive performance and excellent corrosion resistance for terminal blocks.
Glass Filled PA66 Housings provide high mechanical strength and flame retardant property for electrical connectors.
12A Screw Wiring Blocks are widely applied for safe wire connection in various industrial electronic devices.
Dual Pitch Wire Connectors support 7.5mm and 7.62mm pitches to meet diverse PCB layout requirements.
