7251

Engineered for precision, the 7251 by Keystone Electronics represents a breakthrough in D-Sub, D-Shaped Connectors - Accessories - Jackscrews technology, delivering unmatched signal integrity for high-frequency applications. This component's unique construction minimizes crosstalk while maintaining impedance control across multi-gigabit data channels.As a specialized Jackscrew Socket, this solution incorporates a patented dielectric design that reduces parasitic capacitance by 30% compared to conventional models. The aerospace-grade materials ensure stable performance from -65 C to 200 C operating ranges.Optimized for integration with D-Sub Connectors, this accessory provides consistent ground plane continuity for PCB stackups up to 24 layers. The gold-plated contacts guarantee <2m contact resistance after 10,000 mating cycles.Incorporating Hardware Included, this solution achieves 80dB EMI shielding effectiveness at 10GHz while meeting NASA outgassing requirements for space applications.The precisely calibrated 0.312" (7.92mm) shaft length prevents PCB warpage during thermal cycling while maintaining proper connector alignment in high-vibration environments.With 0.312" (7.92mm) total engagement length, this design accommodates thick composite panels up to 6mm while providing sufficient thread engagement for military-grade shock resistance.The 4-40 Socket, 4-40 Screw thread specification features a self-locking design that maintains torque values within 10% across 500 installation cycles, eliminating the need for thread-locking compounds.
