Product details
Product Description:
Huizhou Antenk Electronics Co., Ltd. manufactures AT166 5.0 millimeter pitch PCB screw terminal blocks designed to deliver secure wire to board electrical connection via screw clamping structure for printed circuit board assembly. This terminal block reaches 300 volt rated voltage and 12 amp rated current, supports 18 to 12 AWG wire with 2.5 square millimeter wire cross section and applies 0.5 newton meter recommended screw torque. It adopts PA66 plus twenty three percent glass fiber housing with UL94V 0 flame retardant grade, tin plated brass terminals and nickel plated steel M3 screws, available in multiple pole counts and various insulator color options. This product meets RoHS and HSF environmental standards and fits industrial control modules power supply units precision measuring instruments and general consumer electronic hardware. Operators shall apply recommended torque value during wire installation, select proper pole number and insulator color for actual projects and keep finished products under dry storage to prevent metal component corrosion. Different from competitors outsourcing stamping molding and plating Antenk carries out full in‑house production including independent mold development high speed brass stamping precise PA66 injection molding multi grade electroplating and complete laboratory reliability verification. We hold ISO9001 ISO14001 IATF16949 and UL certifications, provide custom color and pole solution with round‑the‑clock engineering support, and over seventy percent of connector products are exported globally. Feel free to submit your project requirements for sample offer and full datasheet resources.
1. Flame Resistant PCB Connector prevents fire risks and guarantees stable performance for industrial electronic circuit assemblies.
2. Multi Pole Wiring Terminal supports varied contact quantities to realize flexible wire connection on different PCB application scenarios.
3. High Torque Wire Terminal maintains firm screw clamping force and avoids loose wiring under long‑term equipment operation.
