ML-XT™ Sealed Connection System

Molex’s ML-XT sealed connection system integrates high-performance sealing for critical marine-wiring applications in harsh environments

Image of Molex's ML-XT Sealed Connection SystemMolex's rugged ML-XT™ connection system with high-performance seal technology is a cost-competitive solution offering superior reliability for critical vehicle-wiring applications in harsh environments.

Customers specifying low-circuit-count connectors for rugged harness applications in vehicles require a highly reliable, securely sealed connection system to minimize electrical failures and prevent costly machinery downtime. This system needs to withstand high temperatures and harsh environments, including exposure to chemicals, at the lowest cost. The ML-XT system meets these needs with high-performing seal technology proven to prevent ingress of fluids under extreme conditions. Advanced two-shot liquid silicone rubber (LSR) molded one-piece plug, and rear high consistency rubber (HCR) seals with cover guards guarantee optimum seal positioning at all times, including during mating and unmating of the header and receptacle. The result is a cost-competitive solution that achieves superior reliability over de-facto, industry-standard systems.

  • One-piece plug housing and seal design, permanently bonded by two-shot LSR molding technology
    • Prevents fluid ingress; system is IP68-rated (IP69K high-pressure spray validation in process)
    • Prevents loss/misalignment of seal; ensures repeatable retention during unmating and mating of plug and receptacle
  • Latched rear covers
    • Locks-in rear HCR seal
    • Allows for flexible cable exits and cable movement while maintaining optimum seal position to prevent leak paths
  • Rear seals made from HCR
    • Provides greater tear-resistance over LSR material; prevents damage to rear seal during terminal insertion/extraction
  • Plug and receptacle housings are supplied pre-assembled with internal HCR rear seals locked-in by rear covers
    • Reduces inventory, assembly time, and costs for harness manufacturers and prevents loss of rear seals for a cost-competitive mated system
    • Utilizes Molex-proven XRC™ terminals with current ratings up to 13.0
