In the Automotive and Commercial Vehicles industries, engineers are continually challenged to provide more electronics in the same space, accommodating faster assembly times to reduce production costs. The MX150 Connector System offers a reduced package size over traditional USCAR connectors and is designed for simple and secure assembly.
Addressing the strict spatial limitations inherent in modern vehicle architectures, this component features a 12-circuit (12CKT) high-density configuration with a standard 3.5mm pitch. The highly conductive tin-plated male terminals ensure minimal contact resistance and excellent signal integrity. When operators engage the mating halves, the mechanism delivers a distinct tactile click, confirming a secure lock without requiring direct visual inspection deep within crowded chassis frameworks.
Engineered specifically for panel mounting, the Bulkhead Twist-Lock structure simplifies the physical integration into metal or plastic barriers. By utilizing a standardized crimp termination process, production facilities can achieve rapid wire harnessing. This combination not only accelerates manufacturing throughput but also drastically improves the mechanical retention and vibration resistance of the entire wiring harness under dynamic driving conditions.
Customers are looking for a reliable, robust and proven connector design to use for 48V wiring applications. MX150 Mid-Voltage Connectors use the proven MX150 design, upgraded for a voltage rating of up to 60V. To support these elevated electrical loads, the connector body is molded from a specialized, high-strength modified polystyrene alloy. This material formulation grants the housing exceptional thermal stability, enabling continuous operation across a wide temperature gradient from -40°C to +125°C. Such extreme environment tolerance ensures reliable power delivery even when mounted near intense heat sources like engine blocks or exhaust routing.
Customers want to meet the market demand for more powerful, higher performance motors using oil cooling and need electrical connectivity that will work with these designs. MX150 Pass-Through Sealed Connectors are designed to enable oil-cooled electric motor technology through a sealed, oil-resistant design. Beyond mechanical and electrical performance, the 348406410 model strictly complies with global environmental directives. It is fully RoHS and REACH compliant, utilizing a Pb-Free (lead-free) construction. This adherence guarantees that the components meet the stringent ecological entry requirements of international automotive markets, supporting sustainable manufacturing initiatives.
With the mat seal technology, MX150 Connector System is significantly smaller than other comparable USCAR connectors, making it valuable for engineers struggling with space constraint challenges. The compact footprint does not compromise the structural integrity; instead, it provides a streamlined profile that slips easily through tight bulkheads and densely packed wire routing channels.
The design uses potting in the terminal interface, which creates an impermeable barrier against moisture and microscopic dust particles.
The unique two-ring seal option delivers redundancy when compared with typical single-ring sealed connectors, ensuring a backup defense against fluid ingress.
The two-lip ring seal design provides a more reliable seal, maintaining its shape and protective properties even under severe mechanical shock and continuous vibration.
The anti-oil seal is designed specifically for oil-cooled motor applications, formulated to resist chemical degradation and swelling when exposed to synthetic motor oils over long lifespans.
The stackable design includes a connector for the temperature sensor assembly and a connector for the rotary transformer assembly. With other designs, these sub-assemblies are provided by different suppliers. With MX150 Pass-Through Connectors, the combined design provides procurement flexibility and helps reduce supply chain risks. Consolidating these connections into a single, cohesive unit minimizes the number of individual parts required on the assembly line.
To accelerate early-stage design validation and ensure smooth system integration, comprehensive 3D CAD models (including STP files), detailed product specifications, and application notes are readily available. This documentation empowers R&D engineers to accurately visualize the exact spatial footprint, simulate mating clearances, and verify panel cutout dimensions before committing to physical prototyping, thereby shortening the overall development cycle.
Standardized packaging options are meticulously designed to protect the modified polystyrene alloy housings and sensitive tin-plated terminals from deformation or oxidation during global transit. Coupled with transparent lead time management and flexible Minimum Order Quantities (MOQ), this structured supply chain framework effectively minimizes excess inventory holding costs and significantly mitigates the risk of production line disruptions caused by component shortages.
