Its natural (beige/off-white) thermoplastic body matches the original equipment appearance, supporting professional installations where visual consistency and technical accuracy are essential. Built for durability and long-term performance, the TS30378-30P-21 is a trusted component in both DIY and commercial-grade harness manufacturing.

Detailed Product Specifications

Natural-Colored Female Receptacle for Stable Electrical Connections

The TS30378-30P-21 female housing is designed to securely receive the male plug TS30378-30P-11, forming a robust, vibration-resistant junction ideal for automotive environments. Its natural beige color provides visual differentiation from other connectors in the vehicle’s harness bundle, reducing the risk of misconnection during installation or repair. The internal cavity is precisely molded to guide and lock the male pins, ensuring full insertion and optimal contact pressure for consistent signal integrity.

Manufactured from high-grade PBT+GF15% or PA66+GF30%, the housing delivers excellent thermal resistance, mechanical strength, and dimensional stability. These materials prevent cracking or warping under prolonged exposure to heat, UV light, or mechanical stress—common challenges in vehicle interiors and engine compartments.
