7256

The 7256 by Keystone Electronics 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 Socket 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 D-Sub Connectors, the accessory ensures proper shell-to-shell bonding for RF shielding applications. The beryllium copper spring washers maintain constant pressure across thermal expansion cycles.The 0.625" (15.88mm) engagement length is calculated to provide 1.5x thread diameter penetration for aluminum enclosures while preventing bottoming out in thin panels.Precision-engineered at 0.625" (15.88mm), this dimension accommodates stacked PCB configurations with up to four intermediate layers while maintaining proper connector alignment.The 4-40 Socket, 4-40 Screw thread form is optimized for self-tapping installation in composite materials, eliminating the need for pre-tapped inserts in lightweight enclosures.
