Huizhou Antenk Electronics Co Ltd manufactures PCB screw terminal block with 5.0 and 7.5 millimeter pitch for secure wire to board power and signal connections on printed circuit boards. This terminal block adopts PBT insulator housing with UL94V zero flame retardant grade, tin plated brass terminals and M3 nickel plated steel screws, it supports pole counts ranging from two up to twenty four positions and multiple insulator color selections including green blue black grey and orange, complete dimension and tolerance reference can be obtained from official engineering drawing for PCB layout validation. It delivers 250 volt rated voltage and 17.5 ampere rated current, compatible with wire gauge from twenty two to fourteen AWG up to 1.5 square millimeter, recommended tightening torque is 0.5 newton meter. Users strip wire insulation, place conductors inside terminal cavity and tighten M3 screws to achieve stable electrical connection without extra soldering for field wiring. Operators shall follow drawing dimension standards during PCB design, apply correct torque value to prevent thread damage or loose wire contact and store goods in dry clean environment to avoid metal part oxidation. Unlike competitors purchasing key components externally Antenk implements full in house workflow covering mold development metal stamping plastic molding assembly and comprehensive lab performance testing. Our factory holds ISO9001 ISO14001 IATF16949 and UL certifications and over seventy percent finished goods export globally. This terminal block fits industrial control systems digital household appliances power supply modules and precision instrument products. Please share your pole count color choice and project specifications for free sample evaluation and full technical drawing support.
