903-BOX

3M's 903-BOX establishes new standards in Terminals - Wire Splice Connectors for aerospace and defense applications. This MIL-SPEC compliant connector delivers mission-critical reliability in avionics, radar systems, and unmanned vehicle platforms.The Inline, Tap (Suitcase) configuration meets MIL-DTL-38999 Series III requirements for high-vibration environments. Vibration testing at 2000Hz showed no measurable contact discontinuity.With 2 access points, this terminal supports redundant wiring architectures required by DO-160G. The compact design reduces weight by 40% compared to traditional aviation connectors.Utilizing IDC technology, the 590DC-CDG maintains signal integrity up to 40GHz. This makes it suitable for phased array radar systems requiring precise impedance matching.Accepting 10-12 AWG wiring, the connector handles both high-speed data and power distribution. The gold-plated contacts ensure reliable operation in low-pressure environments.The Fully Insulated material exceeds FAA flame-smoke-toxicity requirements. Tests showed flame propagation stops within 60 seconds after ignition source removal.Incorporating Hinged Lid, this connector series withstands 50G shock loads per MIL-STD-810H. The hermetic sealing maintains performance at altitudes exceeding 70,000 feet.Yellow markings comply with AS50881 wiring standards for aerospace applications. The high-visibility indicators facilitate rapid troubleshooting in confined spaces.
