Pass-through sealed connectors for next-gen automotive and industrial applications

Mouser now stocks the MX150 pass-through sealed connectors from Molex. Part of the company's family of robust and reliable MX150 automotive connectors, these pass-through sealed connectors address the industry's increasing demand for high reliability in electric motors for next-generation automotive and industrial applications. This cost-effective solution provides a superior and proven sealed panel-mounted connector that delivers an oil-resistant connection for sealed wire-to-wire and wire-to-board configurations in oil-cooled motors and related resolver/transformer and NTC temperature sensors.

The pass-through sealed connectors include the rugged and field-tested MX150 form factor to help make design assembly simpler and secure while offering a reduced package size over traditional USCAR connectors. The devices have a maximum voltage of 14VDC and a maximum current of 12A. They are configured based on a 12-circuit, dual-row stackable 2x3 connector design, including a connector for the temperature sensor assembly and a connector for the rotary transformer assembly. The stackable design delivers procurement flexibility and reduces supply chain risks compared to other solutions.

These high-performance, high-efficiency, sealed panel-mounted connectors provide quick and accurate mating for 1.5mm terminal systems, and their rugged and reliable operation delivers dependable performance under extreme temperatures, varying degrees of vibration and exposure to moisture and chemicals. The connectors feature an IP6K9K and GMW3191-S3 seal rating and GMW3191-V5 vibration rating per GWM3191 standards. Superior sealing performance is acquired using potting in the terminal interface and a unique two-ring seal option that produces improved reliability and ensures consistent connectivity over single-ring-sealed connectors. The two-lip ring seal design delivers a more solid seal, and the connectors' anti-oil seal makes them ideal for oil-cooled motor applications.

Molex's MX150 pass-through sealed connectors feature a single-piece housing for simplified assembly, brushing mounting, integrated TPA to prevent terminal back-out, and polarized housings to prevent mis-mating.
