High-performance sealed connector system saves space in vehicle applications

A high-performance Molex 1.2mm in-line connector system is now available in Europe from TTI. The new Molex MXP120 sealed connector system for automotive and commercial vehicles is designed to replace traditional 1.5mm terminals in in-line harness applications, saving space and providing high performance within harsh environments. It has been designed using the worldwide AK cavity definition and is compatible with AK and USCAR interfaces The MXP120 system is a 4mm pitch system which meets medium-power application requirements up to 13A and suits most sealed harnessing applications. The single wire seal (SWS) connection system has robust perimeter seals to withstand high-pressure spray environments. The smaller package size of the MXP120 system offers significant space savings compared to existing 1.5mm connection systems and greater current carrying capacity than 0.64mm terminal systems. Consisting of single-row receptacles and single-row blade connectors, physical design features include independent secondary locking (ISL) on female receptacles and primary lock reinforcement (PLR) on the male blade connectors to ensure correct terminal positioning, while an audible click confirms secure mating. All circuit sizes and keying options are scoop proof, due to shrouds on the female receptacles.Female receptacles also feature an integral locking latch with bridge protection to protect them from damage during packaging and storage and prolong service life. The MXP120 system is available in yellow housings validated to meet T3-V2-S2 performance standards for in-vehicle safety system applications, including suplemental inflatable restraints, safety restraint systems, seat-belt pretentioners and airbags. Black housings with standard USCAR polarisation options will be available shortly and are currently being validated to meet T4-V4-S3 (per GMW3191) specifications for high performance (temperatures up to 155C/vibration up to 300m/s²) for use in space-constrained powertrain applications (fuel injections systems, emission controls, ignition coil) and body electronics connections in wet areas (exterior lighting, indicators, door locking mechanisms), says the company.
