Mingjiada Electronics Supplies TE 1-2381216-3 MCON 1.2mm 48-Pin Automotive Connector Sleeves—The Preferred Solution for Waterproof Through-Board Connections in New Energy Vehicle Battery Packs

Product Positioning: 48-pin through-panel sealed housing on the MCON 1.2mm platform

Part number 1-2381216-3 belongs to the TE MCON 1.2mm interconnect system and is a 48-pin (1.2mm × 48) male plastic housing within the new generation of low-voltage through-panel waterproof connectors for battery packs. It is internally described as “48POS, MCON 1.2, TAB HSG ASSY, SLD, COD J.” Its core design objective is to address low-voltage through-panel connections between the inner and outer sides of battery pack wall panels, integrating as many power and signal channels as possible within a limited space while meeting automotive-grade sealing, vibration resistance, and flame retardancy requirements.

Within the MCON 1.2 family, this connector complements other pin-count configurations such as 17P, 22P, and 32P. When a battery pack has a large number of low-voltage circuits requiring high-density, centralized connections, the 48-pin 1-2381216-3 model eliminates the space waste and increased assembly complexity associated with stacking multiple connectors.

Among the above parameters, the wide temperature range of -40°C to 130°C covers temperature shock scenarios encountered by battery packs under extreme cold and high-temperature operating conditions; the IP67/IP6K9K sealing rating ensures that the through-panel interface remains leak-free in water-immersed and high-pressure washdown environments; and the USCAR V2 vibration rating provides proven resistance to the continuous vibrations and shocks experienced during vehicle operation. The power pin’s current-carrying capacity of 15A@80°C enables this connector to transmit low-voltage power while supporting load requirements within a certain power range. The PA GF glass-fiber-reinforced nylon housing maintains structural rigidity while meeting the UL94 V0 flame-retardant standard, thereby reducing the fire risk associated with electrical connectors within the battery pack.

Typical Application Scenarios: Low-Voltage Through-Panel Connections in New Energy Vehicle Battery Packs

The primary application scenario for 1-2381216-3 is low-voltage through-panel interfaces in new energy vehicle power battery packs. Battery packs require reliable connections between internal low-voltage circuits—such as the BMS, sensors, and relays—and external vehicle wiring harnesses, while through-panel locations inherently present dual challenges of sealing and mechanical fastening. This connector uses a separate O-ring instead of the traditional potting method, eliminating the need to wait for additional potting material to cure during installation. This not only simplifies the assembly process on battery pack production lines but also facilitates subsequent maintenance, helping to reduce production time and operational costs.

Its high-density 48-pin layout makes it particularly suitable for medium- to high-capacity battery packs with a large number of low-voltage circuits. At the vehicle level, the technical characteristics of the MCON 1.2mm platform also make it suitable for low-voltage connection points that require sealing and vibration resistance, such as sensors, temperature detection, and auxiliary circuits related to charging ports. For vehicle platforms transitioning from a 12V architecture to 48V mild hybrid or higher-voltage architectures, this connector has been thoroughly validated under a 12V nominal architecture and serves as a proven solution for low-voltage side connections in battery packs.
