Introduction

This product is a mating plug with a maximum working voltage of 48V and a maximum working current of 6.0A (unmated under load). The operating temperature range is 20°C to 70°C, with relative humidity not exceeding 85%. Materials include: insulator — black PBT; housing — black PBT; center pin — nickel-plated brass; terminals — tin-plated brass; spring contacts — tin-plated phosphor bronze. Electrical requirements: dielectric strength — 500Vac for 1 minute; insulation resistance — minimum 100MΩ at 250Vdc; contact resistance — maximum 30mΩ. Mechanical requirements: insertion force — 0.3–2.0kgf; withdrawal force — 0.3–2.0kgf; life cycle — 5,000 mating cycles while maintaining contact resistance maximum 100mΩ and withstanding 500Vac for 1 minute; terminal strength — 500gf applied to the terminal in any direction for 60 seconds while maintaining electrical characteristics with no terminal damage or excessive loosening. Soldering requirements: solderability — minimum 90% coverage when terminals are immersed 2mm in a solder bath at 260 ± 5°C for 3 ± 0.5 seconds; solder heat resistance — no deformation when immersed 2mm in a solder bath at 260 ± 5°C for 10 ± 0.5 seconds; soldering iron durability — no deformation when exposed at 350 ± 10°C for 5 seconds or less. Environmental requirements: low temperature — 48 hours at -40 ± 2°C with no deformation, maintaining contact resistance maximum 50mΩ, insulation resistance minimum 100MΩ at 250Vdc, and no signs of mechanical or electrical damage; high temperature — 48 hours at 85 ± 2°C with relative humidity 45–85%, maintaining contact resistance maximum 50mΩ, insulation resistance minimum 100MΩ at 250Vdc, and no signs of mechanical or electrical damage; humidity — 48 hours at 40 ± 2°C with relative humidity 90–95%, maintaining contact resistance maximum 50mΩ, insulation resistance minimum 100MΩ at 250Vdc, and no signs of mechanical or electrical damage; salt spray — 24 hours at 35 ± 2°C in 5% NaCl mist, with no corrosion after cleaning. Packaging: connectors bulk-packed, 500 pieces per sealed PE bag. Testing is based on IEC 60512-5-2. The maximum current curve is generated from isolated test samples under controlled environmental conditions without considering external factors such as housing, mating cables, or other circuits. The working current curve (derated at 20% of maximum) accounts for external factors and manufacturing variation.
