Unsealed connector system for electronics

The MX150 unsealed connector system by Molex is designed for limited space applications and achieves space-savings over traditional USCAR interfaces and optimum performance for mid-power harness applications.


The MX150 unsealed connector system by Molex is designed for limited space applications and achieves space-savings over traditional USCAR interfaces and optimum performance for mid-power harness applications. Courtesy: MolexMolex's MX150 unsealed connector system is designed for direct connect or in-line mid-power body electronics applications in the automotive industry, where space is limited. The Molex MX150 terminal design helps the unsealed connection system save space.

The hinged Terminal Positioning Assurance (TPA) device, which is molded as part of the housing allows simple terminal insertion and secure terminal seating. The MX150 unsealed connector system’s enlarged push surface helps improve ergonomics, allowing for convenient, USCAR-25 compliant mating and unmating. Harness manufacturers can easily access the terminal latch directly, once the TPA hinge is opened, for quick reworking or field-repairs. In addition, since standard MX150 field-service tools are employed, additional tooling charges are eliminated. 

The MX150 unsealed receptacle and in-line connectors are available in 2-, 3- and 4- circuit versions, though other circuit counts can be developed on request, with custom clip slots for increased design flexibility. To facilitate quick visual installation, 4 polarisation options are offered for each circuit size. The MX150 offers high mating performance for mid-power (14 to 22 AWG) applications by using an integral locking latch. The reinforced front-beam terminal design provides a high contact normal force while minimising the insertion force.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
