Waterproof TYPE C female seat 16PIN sinking plate 1.65 full plastic L=9.0 is a high reliability connector designed specifically for outdoor and industrial environments, supporting USB 2.0 (480Mbps) and PD 3.0 (60W) fast charging. The 16PIN layout integrates power, grounding, and protocol signals, and is designed with a sinking board of 1.65mm (with a height of 1.65mm below the board) to accommodate 1.0-1.6mm PCBs. The all plastic shell is made of LCP material (temperature resistant to 260 ℃, flame retardant UL94V-0), paired with dual sealing rings (inner ring fluororubber+outer ring silicone rubber) to achieve IPX7 waterproof rating (no penetration after soaking in 1 meter of water for 30 minutes). SMT soldering supports reflow soldering (temperature ≤ 260 ℃), with an overall length of 9.0mm and a plug and unplug life of ≥ 8000 times. It is suitable for scenarios with high requirements for waterproofing and lightweight, such as automotive electronics and outdoor equipment.
