The **W2CA-1CC-R2** is a specialized electronic component primarily categorized as a **Limit Switch Unit** (specifically a replacement/switch element) manufactured by **Omron**. It is part of the WL/WLM series of heavy-duty limit switches, designed for industrial automation and mechanical position detection. --- ### 1. General Specifications Below are the primary technical characteristics of the W2CA-1CC-R2: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Omron | | **Component Type** | Built-in Switch / Replacement Unit | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Roller Lever (Internal Mechanism) | | **Connection Type** | Lead Wire (Pre-wired) | | **Durability** | High-precision / Heavy Duty | --- ### 2. Key Electronic Parts & Construction The "R2" designation specifically refers to the internal construction and wiring configuration: * **Switching Element:** Uses a high-precision snap-action mechanism. This ensures that the electrical transition occurs rapidly regardless of the physical speed of the actuator, preventing "arcing" and prolonging contact life. * **Wiring (Lead Wires):** The **-R2** suffix often indicates a specific lead wire configuration. These are usually 3-core or 4-core cables that are pre-attached to the internal switch terminals and encapsulated to prevent moisture ingress. * **Contact Material:** Typically made of **Gold-alloy crossbar contacts** or **Silver**, depending on the specific voltage/current load requirements. Gold-clad contacts are preferred for low-energy (logic level) circuits. --- ### 3. Electrical Ratings The electrical performance depends on whether the load is Resistive or Inductive: | Voltage | Resistive Load | Inductive Load | | :--- | :--- | :--- | | **125 VAC** | 5 A | 3 A | | **250 VAC** | 5 A | 2 A | | **30 VDC** | 5 A | 3 A | --- ### 4. Application and Use Cases The W2CA-1CC-R2 is used as a core module within larger limit switch housings. Its primary functions include: 1. **Safety Interlocking:** Ensuring machine guards are closed before operation. 2. **Position Detection:** Sensing the end-of-travel for CNC beds or conveyor belts. 3. **Maintenance:** Used as a drop-in replacement part for the WL series switches, allowing technicians to fix a switch without replacing the entire outer heavy-duty casing. ---
