The model **CLR-25-10-R-P-A-K11-R8** refers to a high-precision **Linear Swivel Clamp** manufactured by **Festo**. While it is primarily a pneumatic actuator, it contains several "electronic-ready" components and specific mechanical features that interface with electronic control systems. --- ### 1. Technical Specification Overview | Feature | Specification | | :--- | :--- | | **Bore Size** | 25 mm | | **Stroke** | 10 mm | | **Swivel Direction** | Right-hand (R) | | **Cushioning** | P: Flexible cushioning rings/plates at both ends | | **Position Sensing** | A: Via proximity sensor (Electronic interface) | | **Protection** | K11: Clamping strap for sensor mounting | | **Wiper/Scraper** | R8: Dust and weld spatter protection | --- ### 2. Electronic & Sensing Components Although the movement is powered by compressed air, the "electronic" side of this part involves how it communicates with a PLC (Programmable Logic Controller). #### A. Position Sensing (Suffix "A") This unit features an internal **permanent magnet** located on the piston. - **Function:** This allows for non-contact sensing of the piston position. - **Electronic Integration:** It is designed to work with **T-slot proximity sensors** (such as the Festo SMT-8M or SME-8M). - **Signal Output:** These sensors typically provide a PNP or NPN digital signal to an electronic controller to confirm if the clamp is "Open" or "Closed." #### B. The K11 Mounting Interface The **K11** designation refers to the specific hardware used to hold the electronic sensors. - It includes a **clamping strap** or rail that allows the user to slide sensors along the cylinder body to fine-tune the electronic switching point. #### C. Control Interface (Solenoid Valves) To operate this part electronically, it must be paired with an **Electronic Solenoid Valve** (e.g., Festo VUVG series). - **Input:** 24V DC signal from a PLC. - **Action:** The valve converts the electronic pulse into pneumatic pressure to move the swivel clamp. --- ### 3. Mechanical & Environmental Features (R8) The **R8** suffix is critical for the longevity of the electronic sensors in harsh environments: - **Scraper:** It features a specialized metal scraper that prevents dust, chips, or weld spatter from entering the cylinder. - **Protection:** By keeping the piston rod clean, it ensures the magnetic field remains consistent for the electronic sensors, preventing "false triggers" or sensor failure due to mechanical interference. --- ### 4. Typical Application Circuit 1. **PLC Output:** Sends 24V signal to Solenoid Valve. 2. **Actuator:** CLR-25-10 rotates and clamps down. 3. **Proximity Sensor:** Detects the internal magnet, sends a "Clamp Engaged" signal back to the **PLC Input**.
