Product details

Huizhou Antenk Electronics Co., Ltd. manufactures AT2500F-3.5 series back hook plug-in terminal blocks with 3.5mm standard pitch to realize reliable wire to PCB electrical connection for signal and low power circuits, rated at 8A current and 125V voltage, compatible with 22 to 16AWG wires up to 1.5 square millimeters and fixed with M2.0 nickel plated steel screws under 0.2N.m torque. This pluggable terminal block adopts flame retardant PA66 with 23 percent glass fiber reinforced insulator reaching UL94V0 grade, nickel plated phosphor bronze conductive terminals and nickel plated brass wire cages for stable low-resistance contact, supporting multiple pole configurations from 2P to 16P and diverse housing color options including black blue green and gray, equipped with rear hook buckle structure for firm PCB mounting and fully compliant with RoHS and HSF environmental standards. This screw clamp terminal connector is widely applied in industrial control equipment, household air conditioning and washing machine appliances, communication control panels, precision testing instruments, digital audio equipment and electronic drive motors. Operators should match wire gauge with terminal block specifications, tighten fixing screws to standard 0.2N.m torque without over torquing, install the back hook buckle tightly onto PCB boards and store finished terminal blocks in dry sealed packages to prevent metal component oxidation. Unlike competitors outsourcing mold stamping and plastic molding Antenk carries out full independent production workflow covering self-designed plastic and metal precision mold fabrication, high-speed phosphor bronze terminal stamping, glass filled PA66 injection molding, metal nickel electroplating and complete electrical load reliability lab testing, certified with ISO9001 ISO14001 IATF16949 and UL E472792 while meeting RoHS HSF and REACH international environmental norms. We own more than two hundred fifty sets of plastic connector molds and one hundred eighty sets of precision metal terminal molds, provide customizable pole number and housing color solutions, offer round-the-clock professional engineering technical support, and over seventy percent of our terminal block products are exported globally backed by our Guangdong Famous Trademark ANTENK and consistent stable mass production quality.

UL94V0 GF PA66 Terminal Housing delivers high flame retardancy and rigid structural stability for long-term industrial wiring connection environments.

Nickel Plated Phosphor Bronze Terminal maintains steady low contact resistance and strong anti-rust performance under frequent wire plugging operations.

Back Hook Screw Clamp Terminal Block locks firmly onto PCB boards via rear hook design and achieves secure wire fastening with standard torque control.
