Product details

Product Description：

Huizhou Antenk Electronics Co., Ltd. manufactures AT303V series 3.81 millimeter pitch PCB screw terminal block to achieve reliable wire to board electrical connection by screw clamping structure for secure conductor fixing on printed circuit boards, complying with official drawing dimension standards to guarantee stable assembly and consistent electrical performance. This screw type terminal block adopts PA66 233GF insulator housing with UL94V 0 flame retardant grade available in green blue black gray and orange colors, tin plated brass terminals and M2.0 nickel plated steel screws with recommended 0.2N m tightening torque. It is electrically rated for 130V voltage and 9 Amp current, supports wire gauge ranging from 24 AWG to 16 AWG or 1.5 square millimeter cross section, and satisfies RoHS and HSF environmental standards. This terminal block covers pole counts from 2 to 24 positions to match diversified PCB layout requirements and fits automated mass production assembly. It is widely used in industrial control panels, communication hardware, power supply modules, digital household appliances, computer peripherals and precision measuring instruments. Operators need to select suitable pole number and insulator color for actual projects, apply correct 0.2N m screw torque to avoid loose wire or thread damage, match proper wire size and store finished products inside dry sealed packages to prevent metal component oxidation. Unlike competitors outsourcing stamping molding and plating services Antenk implements full in house production including independent plastic and metal mold development, brass terminal high speed stamping, PA66 injection molding, multi grade electroplating and comprehensive laboratory reliability verification. We hold ISO9001 ISO14001 IATF16949 and UL E472792 certifications complying with REACH rules, own over two hundred fifty plastic connector molds and one hundred eighty metal terminal molds, provide custom solutions and round the clock engineering support, and over seventy percent terminal block products are exported globally with stable ANTENK brand production quality.

1. Screw Clamp Terminal Block delivers firm wire locking performance to establish dependable wire to board electrical connections on PCBs.

2. PA66 Insulated Terminal Housing provides excellent flame retardant and mechanical strength for long term industrial application scenarios.

3. M2.0 Ni Plated Screw ensures stable clamping force and effective corrosion resistance under specified 0.2N m tightening torque.
