Interconnection


Automotive sealed interconnect platform

22 July 2015 Interconnection

A high-performance, 1,20 mm in-line connector system from Molex is now available from TTI.

The MXP120 range for automotive and commercial vehicles is designed to replace more usual 1,50 mm terminals in in-line harness applications, saving space and providing high performance within harsh automotive environments. It has been designed using the worldwide AK cavity definition and is compatible with AK and USCAR interfaces.

This 4 mm pitch system meets medium-power application requirements up to 13 A and suits most sealed harnessing applications, with a single wire seal connection system having robust perimeter seals to withstand high-pressure spray environments.

The smaller package size of the MXP120 system offers significant space savings compared to existing 1,50 mm connection systems and greater current carrying capacity than 0,64 mm terminal systems. Consisting of single-row receptacles and single-row blade connectors, physical design features include independent secondary locking on female receptacles and primary lock reinforcement 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, thanks 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 supplemental inflatable restraints, safety restraint systems, seat-belt pre-tensioners 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 155°C/vibration up to 300 m/s²) for use in space-constrained powertrain applications and body electronics connections in wet areas.
