The **ITH03FPR36SW** is a high-performance, high-voltage circular connector primarily used in industrial and military-grade applications. It belongs to the **ITH series**, which is based on the MIL-DTL-5015 standard but features a quick-disconnect reverse bayonet coupling mechanism. --- ### 1. Key Technical Specifications Below is a breakdown of the electronic and mechanical characteristics of the ITH03FPR36SW: | Feature | Specification | | :--- | :--- | | **Series** | ITH (Reverse Bayonet) | | **Shell Size** | 36 | | **Contact Gender** | Socket (Female) | | **Mounting Style** | Rear Panel Mount (Square Flange) | | **Termination** | Solder or Crimp (Depending on specific insert) | | **Coupling Type** | 3-point Reverse Bayonet | | **Environmental Rating** | IP67 (when mated) | --- ### 2. Detailed Component Breakdown #### A. Shell Design (ITH03) The "03" prefix indicates a **Rear Panel Mount Receptacle** with a square flange. This is designed to be bolted onto a panel from the inside, providing a secure, vibration-resistant connection point for external cables. #### B. Reverse Bayonet Mechanism Unlike standard threaded connectors, the "ITH" series uses a **Reverse Bayonet** locking system. - **Benefit:** It requires only a 120-degree turn to lock. - **Feedback:** It provides an audible and tactile "click" to confirm a full mate. - **Durability:** High resistance to vibration and shock, preventing accidental decoupling. #### C. Material and Plating The shell is typically constructed from high-strength aluminum alloy. The "SW" suffix often refers to a specific finish or modification: - **Standard Finish:** Cadmium with Olive Drab chromate or Black Zinc Cobalt. - **Inserts:** Made of high-insulation synthetic rubber (Chloroprene) that offers excellent resistance to fuels, oils, and low temperatures. --- ### 3. Application Areas Due to its rugged construction, this part is commonly found in: 1. **Mass Transit/Railway:** Inter-vehicle connections and power distribution. 2. **Military Ground Vehicles:** Powering sensors and communications arrays. 3. **Heavy Machinery:** Industrial automation in harsh environments. 4. **Power Electronics:** High-current delivery systems requiring environmental sealing. --- ### 4.
