The **W2TS-4A3-R/N** is a specific electronic component belonging to a series of high-performance connectors, typically used in automotive or industrial sensor applications. Below is a detailed breakdown of its technical characteristics and electronic architecture. --- ### 1. General Specification Overview This part is a terminal connector system designed for signal integrity in harsh environments. The "R/N" suffix usually denotes specific keying or color-coding configurations for error-proofing during assembly. | Feature | Specification Details | | :--- | :--- | | **Series** | W2TS (Automotive/Industrial Grade) | | **Pin Configuration** | 4-Pin / 4-Circuit | | **Gender** | Receptacle (Female Housing/Connector) | | **Termination Style** | Crimp / Wire-to-Wire or Wire-to-Board | | **Application** | Sensor interfaces, ECU connections, LED modules | --- ### 2. Key Electronic & Mechanical Parts The assembly of the W2TS-4A3-R/N consists of several integrated sub-components that ensure electrical connectivity: #### A. Housing Body * **Material:** High-temperature Thermoplastic (PBT or Nylon). * **Function:** Provides insulation between the four circuits and physical protection for the metal terminals. * **Locking Mechanism:** Features an integrated locking ramp or latch to prevent accidental disconnection due to high vibration. #### B. Contact Terminals (Internal) * **Material:** Copper Alloy (Phosphor Bronze or Brass). * **Plating:** Usually Tin or Gold plating to minimize contact resistance and prevent oxidation. * **Current Rating:** Typically supports low to medium current (approx. 3A to 5A depending on wire gauge). #### C. Sealing Components (The "W" in W2TS) * **Material:** Silicone rubber or Gel. * **Ingress Protection:** Often rated for IP67 or IP69K. It includes a matte seal (at the wire entry) and an interfacial seal (between mating connectors) to block moisture and dust. --- ### 3.
