The part number **CLR-63-20-R-P-A-K11-R8** identifies a specific **Linear Swivel Clamp** manufactured by **Festo**, a leader in automation technology. While this is primarily a pneumatic/mechanical actuator, it contains specific electronic and integration components defined by its suffix. --- ### Part Breakdown and Technical Specifications | Code | Feature | Description | | :--- | :--- | :--- | | **CLR** | Series | Linear swivel clamp (combines linear stroke with a rotation). | | **63** | Piston Diameter | 63 mm (determines the clamping force). | | **20** | Stroke Length | 20 mm total stroke. | | **R** | Swivel Direction | Swivels to the **Right** during the clamping motion. | | **P** | Cushioning | Flexible cushioning rings/plates at both ends to reduce impact. | | **A** | Position Sensing | **Integrated Magnet** in the piston for proximity sensors. | | **K11** | Protection | Specific dust/scrap protection or bellows (Application-specific). | | **R8** | Dust Protection | Enhanced protection against dust and welding spatter. | --- ### Key Electronic Components The "Electronic" aspect of this part refers to how it interfaces with a PLC (Programmable Logic Controller) or a control system. #### 1. Magnetic Position Sensing (Code: A) The piston contains an internal permanent magnet. This allows the attachment of **proximity sensors** (typically T-slot sensors like the Festo SMT or SME series). * **Function:** Detects if the clamp is "Open" or "Closed." * **Signal Type:** Digital (PNP, NPN, or Reed contact). * **Connection:** Usually M8 or M12 connectors or open cable ends. #### 2. Control Interface To operate this unit electronically, it must be paired with a **Solenoid Valve**. * **Requirement:** 5/2-way or 5/3-way valve. * **Voltage:** Commonly 24V DC for industrial automation. * **Feedback Loop:** The sensors send a 24V signal back to the PLC once the mechanical stroke is completed. --- ### Usage in Automated Systems This specific configuration (with R8 dust protection) is often used in **Welding Cells** or **Woodworking**, where electronic sensors must be protected from harsh environments while providing precise feedback to the main controller. ---
