3.5mm Pitch PCB Screw Terminal Block

Product Description:

Huizhou Antenk Electronics Co., Ltd. manufactures AT333‑3.5XXX‑A series 3.5 mm pitch PCB screw terminal block to deliver firm screw locked wire connection for printed circuit board assembly, supporting contact poles ranging from 02 contacts up to 24 contacts and following drawing dimensional tolerances to ensure stable PCB soldering performance. This screw terminal block adopts PBT insulator housing with UL94V 0 flame retardant grade, tin plated brass terminals and M2 nickel plated steel screws with recommended tightening torque of 0.2N.m, electrically rated for 250V voltage and 7A working current and fits wire gauge from 28 AWG to 18 AWG equivalent to 1.0 square millimeter wire cross section. Multiple insulator color selections including green blue black gray and orange satisfy diverse wiring identification needs and the product meets RoHS and HSF environmental standards. This reliable screw type terminal block is widely deployed in communication hardware, industrial control panels, digital household appliances, computer peripherals, automotive electronic assemblies and precision measuring instruments. Operators need to select correct pole number and housing color for practical wiring demands, use proper torque during screw tightening operation, avoid over torque to prevent housing or screw damage, and store finished terminal blocks inside dry sealed packages to protect metal components from oxidation. Unlike competitors outsourcing mold stamping and molding procedures Antenk carries out complete in house production workflow covering self developed precision plastic and metal mold fabrication, brass terminal high speed stamping, high temperature PBT injection molding plus comprehensive laboratory reliability verification, holding ISO9001 ISO14001 IATF16949 and UL E472792 certifications compliant with REACH rules. We own over two hundred fifty plastic connector molds and one hundred eighty metal terminal molds, deliver custom solutions and round the clock professional engineering support, and over seventy percent of our terminal block products are exported globally backed by ANTENK brand and stable mass production quality.
