1857211-4

The 1857211-4 by TE Connectivity AMP Connectors sets new benchmarks in the D-Sub, D-Shaped Connectors - Accessories - Jackscrews segment, offering unparalleled mechanical retention for next-gen high-speed digital interfaces. This advanced jackscrew design reduces insertion loss by 15% through optimized grounding paths.This Jackscrew, Slotted variant incorporates a unique conductive polymer coating that eliminates ESD risks while maintaining <5m contact resistance. The captive design prevents loose hardware in vibration-prone installations.Validated with AMPLIMITE Series HDE, HDP, the accessory ensures proper shell-to-shell bonding for RF shielding applications. The beryllium copper spring washers maintain constant pressure across thermal expansion cycles.With integrated Clip, this solution meets DO-160G standards for lightning strike protection while providing 360 RF shielding continuity in avionics applications.Precision-engineered at 0.228" (5.80mm), this dimension accommodates stacked PCB configurations with up to four intermediate layers while maintaining proper connector alignment.The M3 thread form is optimized for self-tapping installation in composite materials, eliminating the need for pre-tapped inserts in lightweight enclosures.
