Based on the model number, the **CVR1-BE-R** is an **I/O module connector** (specifically a Cover/Shell kit) typically used within the **Mitsubishi Electric MELSEC-L Series** or similar programmable logic controller (PLC) peripheral ecosystems. Here is a breakdown of the electronic and mechanical specifications for this component: --- ## 1. General Specifications The CVR1-BE-R is primarily a **housing/connector kit** designed to facilitate secure wiring for high-density I/O modules. | Feature | Description | | :--- | :--- | | **Component Type** | Connector Cover / External Terminal Interface | | **Orientation** | Right-angle / Side-entry (indicated by "-R") | | **Compatibility** | Mitsubishi MELSEC-L, D-Sub, or high-density pin headers | | **Material** | ABS Plastic or Metal-plated Resin (EMI shielding) | --- ## 2. Key Electronic Features While the part is primarily a mechanical interface, its design serves specific electronic functions: ### A. EMI/RFI Shielding The "BE" designation often refers to a metallic or metal-coated finish. This provides a **Faraday cage effect**, protecting the low-voltage signals (24V DC logic) from electromagnetic interference generated by nearby motors or high-voltage relays. ### B. Pin Configuration These connectors are usually designed for **40-pin** or **37-pin** high-density layouts. * **Voltage Rating:** Typically rated up to 30V DC. * **Current Rating:** Approximately 0.5A to 1.0A per pin (signal level). ### C. Connection Mechanism * **Strain Relief:** Prevents physical tension on the soldered or crimped wires from damaging the PLC's internal PCB headers. * **Locking Screws:** Ensures that the connection remains stable even in high-vibration industrial environments. --- ## 3. Physical Dimensions & Layout The "R" suffix indicates a **Right-Angle** exit for the cables. This is critical for shallow control panels where there isn't enough clearance for cables to stick straight out of the PLC face. ### Component Parts List 1. **Top & Bottom Shell:** The protective casing. 2. **Cable Clamp:** Metal bracket to secure the main cable bundle. 3. **Jackscrews:** Manual or screwdriver-driven bolts to lock the unit to the PLC. 4. **Insulator:** Internal plastic divider to prevent short-circuiting between pins. --- ## 4. Usage Scenario Typically, you would use this part when wiring a **Transistor Output Module** (like the LY41NT1P) or a **DC Input Module**. You would solder your field wires to a compatible male/female header, then encase that header in the **CVR1-BE-R** before plugging it into the PLC rack.
