Molex ML-XTTM Sealed Connection System Delivers Market-Leading Seal Technology for the Commercial Vehicle Market

By Business Wire News


Molex Incorporated introduces its ML-XT™ Sealed Connection System, a highly reliable, securely sealed solution that minimizes electrical failures in gruelling commercial vehicle applications while delivering assembly cost savings to original equipment manufacturers and harness makers. Rated IP68 and J2030 power-wash capable, the ML-XT system features a one-piece plug housing and seal design, which is permanently bonded using cutting-edge, two-shot LSR (liquid silicone rubber) molding technology. This ensures definitive and repeatable retention of the plug seal and prevents the seal from rolling during un-mating and mating to guarantee correct seal positioning. It also eliminates the risk of a lost or forgotten seal during installation and maintenance.

“Most standard systems are supplied without rear seal covers for the housing, leaving the seal exposed and unprotected,” said Denis O’Sullivan, global product manager, Molex. “The ML-XT system includes housings that are pre-assembled with the rear seal securely locked-in place and protected by a latched rear cover. In addition, the need for welding is removed. This allows Molex to deliver a cost-competitive drop-in replacement for the defacto commercial vehicle standard sealed connectors used in multiple harsh duty applications.”

The ML-XT rear seals are made from high consistency rubber (HCR) for greater tear resistance and protection during terminal insertion and extraction. The protective rear covers allow for flexible cable exits and cable movement while maintaining the optimum seal position to prevent leak paths. Wedgelocks or TPAs (Terminal Position Assurance) lock the terminals in position for a reliable electrical contact while the plug housing features an integral locking latch for secure mating.

The ML-XT system is currently offered in 2-, 4-, 6- and 18-circuit options, providing design flexibility for a vast range of sensor technologies and low circuit-count applications. The proven Molex XRC™ terminals deliver current ratings up to 13.0A while the nine color-coded housings enable easy visual mating of harnesses to prevent mis-mating.

“By delivering a one-piece housing solution, Molex helps customers reduce purchasing and inventory costs while simplifying assembly. Additionally, the market-leading reliability of ML-XT connectors minimizes electrical failures and helps prevent machinery downtime for greater operational efficiencies not only in commercial vehicle applications but in the automotive, military vehicle, marine and aeronautical industries as well,” added O’Sullivan.
