Molex ML-XT Sealed Connection System

ML-XT™ sealed connection system

The rugged ML-XT™ connection system with market-leading high-performance seal technology is a cost-competitive solution offering superior reliability for critical vehicle-wiring applications in harsh environments.

As vehicles and their environments become more complex, the demand placed on connectors and their seals is greater than ever before. With greater intricacy comes an increased risk of failure, as one compromised seal on a single connector can lead to the failure of an entire system.

As a result, engineers are specifying that connectors for vehicles operating in rugged harness applications have a highly-reliable and securely sealed connection system. This minimises electrical failures and prevents costly machinery downtime. Systems need to withstand high temperatures and harsh environments, including exposure to chemicals, at the lowest cost.

With multiple breakthrough innovations, Molex’s ML-XT sealed connection system meets these needs with high-performing seal technology that has completely redefined seal reliability in vehicles.

TE Connectivity Interconnect System


Features Applications
  • Covalently interlocked one-piece plug housing and interfacial seal formed by 2-shot LSR (liquid silicone rubber) moulding technology
  • Drop in replacement for defacto-standard industry connectors
  • Rear seals made from HCR (high consistency rubber)
  • Latched rear covers lock-in rear HCR seals without exceeding the perimeter of the housings
  • Plug and receptacle housings are supplied pre-assembled with internal HCR rear seals and covers
  • Utilises Molex proven XRC™ terminals with current ratings up to 13.0A
  • High terminal retention force; exceeds 111N
  • Wedgelock / TPA (Terminal Position Assurance) loaded after terminals
  • Plug housing features integral locking latch with finger grip
  • Colour-coded housings available
  • Prevents fluid ingress; system is IP69K-rated and J2030 power-wash test capable
  • Prevents fluid ingress; system is IP69K-rated and J2030 power-wash test capable
  • Prevents loss/ misalignment of seal; ensures repeatable retention during unmating and mating of plug and receptacle
  • Achieves superior reliability without the need for costly re-design
  • Provides greater tear-resistance over LSR material; prevents damage to rear seal during terminal insertion/ extraction
  • Allows for flexible cable exits and cable movement whilst maintaining optimum seal position to prevent leak paths
  • Reduces inventory, assembly time and costs for harness manufacturers. Prevents loss of rear seals for a cost-competitive mated system
  • Supports tooling widely used at harness makers
  • Withstands high axial pull-out forces per J2030 specification
  • Locks terminals in position for secure electrical contact
  • Enables easy handling and secure mating of plug and receptacle
  • Facilitates easy visual mating of harnesses to prevent mis-mating
