37-Way Female Grey Automotive connector – TS30407-37P-21 Replacement for JAE MX58037SFA

The TS30407-37P-21 is a high-quality 37-way female grey automotive connector designed as a reliable replacement for the JAE MX58037SFA model. Engineered for precision and durability, this connector serves as a critical component in vehicle audio systems, control modules, and wire harness assemblies across various automotive platforms including passenger cars, marine yachts, and utility task vehicles (UTVs). As the female mating housing to the TS30407-37P-11 male connector, it ensures stable electrical connectivity with secure fitment, making it ideal for applications where signal integrity and vibration resistance are essential.

Constructed from premium-grade engineering plastics—either PBT+GF15% or PA66+GF30%—this housing delivers outstanding thermal stability, mechanical strength, and resistance to environmental stress. The light grey color provides clear visual differentiation, helping technicians identify correct pairing during installation or repair, especially in complex multi-harness environments. Compatible with copper alloy, brass, and phosphor bronze terminals, it supports consistent conductivity across all 37 circuits, ensuring reliable performance in both analog and digital signal transmission systems such as infotainment units, ECU interfaces, and sensor networks.

Product Specifications

Precision-Built for Demanding Automotive Environments

The TS30407-37P-21 is designed to perform reliably under harsh operating conditions commonly found in automotive systems. Its reinforced thermoplastic housing resists deformation due to temperature fluctuations, UV exposure, and mechanical impact, ensuring long-term functionality in engine bays, dashboards, and cabin-mounted installations. The precise mold tolerances guarantee smooth mating with the corresponding male connector, minimizing insertion force and preventing terminal damage during repeated connection cycles.

This connector supports robust signal transmission for factory audio systems and control modules, where even minor disruptions can affect system performance. The light grey housing enhances visual identification, reducing the risk of mis-mating in service or assembly scenarios involving multiple similar connectors. With its durable construction and stable contact design, it meets the demands of modern vehicles requiring dependable electrical interconnects.
