Features and Benefits

GMW3191 specifications:
• Designed specifically for high-vibration under-the-hood applications
• Meets IP67, IP68 and IP69k sealing specs, Temp Class III operating temperature specs and Vibe Class I vibration specs

Center-wall feature:
• Prevents scooping
• Extends past the length of the terminals to enable connection in blind-mate conditions

Header terminal filtering:
Eliminates cross talk between adjacent circuits in up-integrated systems

PCB tail customization: solder-tail or compliant-pin technology:
Enhances PCB design flexibility

Precious-metal plating:
Stabilizes contact resistance under severe temperature and vibration conditions

Matte-seal technology:
• Allows closer center-to-center terminal spacing, which reduces packaging size to the smallest in the industry
• Eliminates the need for crimping individual cable seals
• Reduces harness-assembly complexity

Integrated TPA and CPA components:
• Assists mating reliability
• Protects against un-mating in high-vibration environments. Reduces assembly complexity

Six unique mechanical polarization options and unique color coding:
Offers the ability to use multiple connectors on one module while eliminating the risk of cross-mating incorrect connectors

Two wire-dress options:
Creates flexibility in wire-routing design with both 0° and 180° orientations

Overview

Automotive powertrain OEM’s have needed a connection system specifically designed for engine and transmission control module applications. These modules are located in harsh, high-vibration environments under the hood or chassis of automobiles, so connector retention and durability are very important requirements. In order to seamlessly fit into the modules, packaging size is an important attribute for these applications as well.

The MX123 Sealed Connection System is certified to GMW3191 specs, which means that the product has been tested, and has performed well in, very harsh, hot, high-vibration environments. The system utilizes matte-seal technology to create an extremely resilient sealed connector system with the smallest packaging size in the industry. Multiple polarization, wire-dress and PCB-tail options and integrated TPA and CPA components assist in keeping the interface mated and free up valuable time in the assembly process.
