The **JL05-28EB2A-R** is a specific electronic component accessory, primarily categorized as a **Circular Connector Backshell (Endbell)**. It is manufactured by JAE (Japan Aviation Electronics) and is designed for use with the JL05 series of waterproof, high-reliability circular connectors. --- ### 1. Technical Specifications The part number can be broken down to understand its physical and technical attributes: | Feature | Specification | | :--- | :--- | | **Series** | JL05 (Waterproof Circular) | | **Part Type** | Endbell (Backshell) | | **Shell Size** | 28 | | **Angle** | Straight (EB style) | | **Environmental Rating** | IP67 (when mated) | | **RoHS Compliant** | Yes (indicated by the "-R" suffix) | --- ### 2. Primary Functions This component serves three critical roles in an electronic assembly: * **Strain Relief:** It protects the soldered or crimped wire terminations inside the connector from mechanical stress caused by pulling or bending the cable. * **Environmental Protection:** It acts as a housing to seal the rear of the connector against water, oil, and dust, maintaining the IP67 integrity of the system. * **Cable Management:** It provides a structured exit point for the wiring harness, allowing for secure clamping of the cable jacket. --- ### 3. Materials and Construction The JL05 series is known for its "Industrial Grade" build quality, suitable for heavy machinery and automation. * **Body Material:** Typically an Aluminum alloy with a protective finish (usually Zinc plating or Black chromate). * **Coupling:** It features a screw-on mechanism to attach to the rear thread of a size 28 JL05 plug or receptacle. * **Gasket/O-ring:** Integrated synthetic rubber seals to prevent fluid ingress. --- ### 4. Typical Applications You will commonly find the JL05-28EB2A-R in the following environments: 1. **Industrial Automation:** Servo motors and robot arm power/signal interfaces. 2. **Machine Tools:** CNC machines where coolant and metal chips are present. 3. **Heavy Equipment:** Construction or agricultural vehicles requiring ruggedized interconnects. ---
