1.Product Description
Huizhou Antenk Electronics Co Ltd manufactures five point zero and five point zero eight millimeter pitch screw type PCB terminal block for stable wire to board power and signal interconnection across various electronic devices. This screw clamping terminal block adopts black PBT insulator housing with UL94V zero flame retardant grade, tin plated brass terminals and M2 point five nickel plated steel screws with recommended zero point four newton meter tightening torque, it supports contact pole positions ranging from two up to twenty four poles and offers multiple insulator color options including green black gray and orange, complete dimension tables and PCB layout tolerance data can be obtained from official engineering drawing for PCB footprint validation. It delivers two hundred fifty volt rated voltage and seventeen point five ampere rated current and accepts wire gauge from twenty two to fourteen AWG up to one point five square millimeter. Users strip wire insulation, insert conductor into terminal cavity and fasten nickel plated steel screw with proper torque then solder terminal block pins onto printed circuit board to achieve reliable electrical connection. Operators shall follow drawing dimension standards during PCB design, apply proper screw torque to avoid component damage and store goods in dry clean environment to prevent 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 modules consumer electronic hardware household appliances and precision instrument products.
