MXP120™ Sealed Connector System

The MXP120™ Sealed Connector System is a high-performance 1.20 mm terminal in-line connection system for automotive and commercial vehicles. The use of 1.20 mm terminals minimizes the connector interface and connector package size versus larger 1.50 mm terminals while offering more current carrying capacity and robustness in assembly than is possible with the use of 0.64 mm terminal systems.

Connectors in yellow housings are validated to meet T3-V2-S2 performance level for in-vehicle safety system applications. Black housings with standard USCAR polarisation options will follow. These housings are being validated to meet T4-V4-S3 specifications (per GMW3191) for high-performance (temperatures up to 155°C/vibration up to 300 m/s²) for use in space-constrained powertrain applications.

Features and Benefits Include:

4.00mm pitch connection system based on 1.20mm terminals Meets medium-power application requirements up to 13.0A
Suitable for most sealed harnessing applications
Single wire seal (SWS) connection system with robust perimeter seal Withstands high-pressure spray environments
Reduced package size when compared to existing 1.50mm connection system Offers significant space-savings for confined design parameters
Accommodates wire gauges up to 1.00mm² Limits connector pitch to 4.00mm with SWS
Compatible with AK or USCAR interface; designed using worldwide AK cavity definition Globally accepted and marketable
Female receptacles feature long shrouds for 1 by 4 circuit and above (short shrouds for below 1 by 4 circuit) Ensures all circuit sizes and keying options are scoop proof
Female receptacles with Independent Secondary Locking (ISL)
Male blade connectors with Primary Lock Reinforcement (PLR)
Ensures efficient terminal positioning and detection of partial installation
Female receptacles feature integral locking-latch with bridge protection and audible click Secure mating performance
Avoids damage to the latch during packaging and transit
