The **CLR-50-20-R-P-A-K11-R8** is a part number for a high-precision **Linear Swivel Clamp** manufactured by **Festo**. This component is a pneumatic actuator that combines linear motion with a rotation (swivel) to secure workpieces in automated environments. --- ### Technical Breakdown of the Part Number | Code Segment | Feature | Description | | :--- | :--- | :--- | | **CLR** | Product Series | Linear Swivel Clamp | | **50** | Piston Diameter | 50 mm diameter | | **20** | Stroke | 20 mm total stroke (Linear + Swivel) | | **R** | Swivel Direction | Right-hand swivel (Clockwise) | | **P** | Cushioning | Flexible cushioning rings/plates at both ends | | **A** | Position Sensing | Proximity sensor ready (Magnetic piston) | | **K11** | Clamping Finger | Includes a clamping finger with a protective cap | | **R8** | Dust Protection | Enhanced dust and splash protection (R8 coating/seal) | --- ### Key Electronic and Electromechanical Components While the unit is primarily pneumatic, its integration into electronic control systems relies on several key features: #### 1. Position Sensing (Code: "A") The "A" designation indicates that the internal piston is equipped with a **permanent magnet**. This allows for the use of electronic **Proximity Sensors** (typically T-slot or C-slot sensors like the Festo SMT-8M-A). * **Function:** Detects when the clamp is in the "Open" or "Closed" position. * **Output:** Typically 24V DC PNP or NPN signals sent to a PLC (Programmable Logic Controller). #### 2. Control Interface To operate this part electronically, it must be paired with a **Solenoid Valve**. * **Valve Type:** Usually a 5/2-way valve (5 ports, 2 positions). * **Activation:** The PLC sends an electrical signal to the solenoid coil, which shifts the valve and directs compressed air to move the clamp. #### 3. Environmental Protection (Code: "R8") The **R8** specification provides enhanced protection for the mechanical parts, which is crucial for electronic reliability. By preventing dust, metal chips, or fluids from entering the cylinder, it ensures the magnetic piston remains detectable by external electronic sensors without interference or mechanical failure. --- ### Specifications Table | Feature | Value | | :--- | :--- | | **Operating Pressure** | 2 bar to 10 bar | | **Operating Medium** | Compressed air (ISO 8573-1:2010) | | **Ambient Temperature** | -10°C to 80°C | | **Clamping Force (6 bar)** | Approx. 950 N | | **Material** | Wrought Aluminum Alloy (Housing), High-alloy Steel (Piston rod) |
