1688683

Phoenix Contact's 1688683 revolutionizes Modular Connectors - Accessories applications through its patented contact geometry and advanced dielectric materials. This product delivers exceptional performance in high-vibration environments while maintaining consistent characteristic impedance.The Frame configuration features gold-plated beryllium copper contacts with 50 plating thickness. This premium construction ensures contact resistance remains below 10m even after 10,000 vibration cycles at 20G acceleration.Designed for seamless interoperability with RJ45 Socket Inserts, this accessory supports 10BASE-T1S automotive Ethernet. The optimized geometry reduces stub lengths to <1mm, minimizing signal reflections in multi-drop configurations.With its IP20 implementation, the design achieves 100M insulation resistance at 500VDC. The gas-tight contact interface prevents fretting corrosion even in high-humidity environments, ensuring reliable operation over 15+ year service life.Gray indicators utilize laser-etched markings that withstand 500+ cleaning cycles. These permanent identifiers meet IATF 16949 requirements for automotive traceability while maintaining excellent contrast ratios (>70%) under various lighting conditions.
