1.Product Description
Huizhou Antenk Electronics Co Ltd manufactures 2.5 millimeter pitch screw type PCB terminal block for secure wire to board power and signal interconnection for diverse electronic hardware. This screw clamping terminal block adopts PA66 plus twenty three percent glass fiber insulator housing with UL94V zero flame retardant grade, tin plated brass terminals and M2 point zero nickel plated steel screws with recommended zero point two newton meter tightening torque, it supports contact pole positions ranging from two up to twenty four poles and provides multiple insulator color selections including green blue 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 one hundred fifty volt rated voltage and eight ampere rated current and accepts wire gauge from twenty six to eighteen AWG up to one point zero square millimeter. Users strip wire insulation, place conductor inside terminal cavity and fasten nickel plated steel screw with proper torque then solder block pins onto printed circuit board to achieve stable electrical connection. Operators shall follow drawing dimension standards during PCB design, apply correct screw torque to avoid thread damage and store goods in dry clean environment to prevent metal component 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. Please share your pole count color choice and project specifications for free sample evaluation and full technical drawing support.
GF Reinforced Terminal Housing delivers enhanced mechanical strength and high temperature stability for long‑term PCB terminal block operation.
Nickel Plated Screw Fastener provides reliable anti‑corrosion performance and stable clamping force for wire connection.
Multi Color Screw Terminal supports various housing color selections for quick circuit identification on printed circuit boards.
