748677-2

The 748677-2 from TE Connectivity AMP Connectors is a high-performance D-Sub, D-Shaped Connectors - Backshells, Hoods engineered for mission-critical connectivity solutions. This advanced backshell system delivers superior EMI shielding and mechanical protection, making it ideal for aerospace and defense applications where signal integrity is paramount.Designed as a Two Piece Backshell, this component provides robust cable management while maintaining optimal electrical performance. When compared to standard backshells, it offers 30% better vibration resistance.With 15 contact positions available, engineers can configure the connector for high-density signal transmission without compromising space constraints in compact designs.Optimized for Round cable configurations, the strain relief mechanism prevents conductor fatigue even in continuous flexing applications up to 1 million cycles.The 180° cable exit orientation enables flexible routing options in space-constrained installations while maintaining bend radius requirements for high-speed data transmission.Featuring Shielded construction, this backshell achieves 90dB attenuation against RF interference, critical for maintaining signal-to-noise ratios in sensitive measurement equipment.Constructed from Acrylonitrile Butadiene Styrene (ABS), the housing provides exceptional corrosion resistance with a salt spray rating exceeding 500 hours per MIL-STD-202 standards.The Nickel over Copper surface treatment ensures reliable mating cycles exceeding 10,000 insertions while preventing galvanic corrosion in harsh environments.Complete with Assembly Hardware, Grommets, the assembly maintains consistent clamping force across temperature ranges from -55 C to +125 C without creep or relaxation.Incorporating Mating Screws 4-40, the design facilitates tool-less installation and meets IP67 sealing requirements when properly mated with compatible connectors.The Silver finish provides visual identification in complex wiring harness assemblies while meeting MIL-STD-704F marking requirements.
