The **FLCS-1C-R** is a specific electronic component typically categorized as a **Liquid Level Float Switch**. These devices are used to detect the level of liquid within a tank and trigger a response (such as starting a pump or sounding an alarm) based on that level. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Type** | Float Level Switch | | **Configuration** | Single Point (1C usually denotes SPDT or specific mounting) | | **Material** | Often Stainless Steel or High-Grade Plastic (depending on variant) | | **Mounting** | Side or Top Mount (Vertical) | | **Switching Voltage** | Typically up to 250V AC / 200V DC | | **Switching Current** | Max 0.5A to 1.5A (varies by load type) | | **Contact Form** | Form C (SPDT - Single Pole Double Throw) | --- ### 2. How it Works The FLCS-1C-R operates using a magnetic reed switch mechanism: 1. **The Float:** A buoyant float contains a permanent magnet. 2. **The Stem:** Inside the stationary stem is a hermetically sealed reed switch. 3. **Activation:** As the liquid level rises or falls, the float moves along the stem. When the magnet inside the float aligns with the reed switch, the magnetic field forces the switch contacts to open or close. ### 3. Wiring Configuration (SPDT) The "1C" in the part number usually refers to a **Form C** contact arrangement. This provides three wires: * **COM (Common):** The shared terminal. * **NO (Normally Open):** The circuit is open when the float is at its rest position. * **NC (Normally Closed):** The circuit is closed when the float is at its rest position. ### 4. Typical Applications * **HVAC Systems:** Monitoring condensate overflow in air conditioning units. * **Industrial Tanks:** Low or high-level alerts for chemicals or water. * **Sump Pumps:** Triggering the pump when water reaches a specific height. * **Medical Equipment:** Monitoring fluid levels in laboratory waste or supply containers. --- ### 5. Installation Precautions * **Orientation:** Ensure the "R" (Right-angle or specific orientation) is mounted correctly to allow the float free movement. * **Load Protection:** Because reed switches have low current ratings, you should use a **Power Relay** or **Contactor** if you are controlling high-power devices like motors. * **Fluid Compatibility:** Ensure the material of the FLCS-1C-R is compatible with the liquid being measured (e.g., oil vs. acidic water).
