The **W2CA-113-R** is a specific part number associated with industrial control equipment, typically identified as a **Limit Switch Component** or a **Contact Block** manufactured by brands like Omron or specialized industrial suppliers. Below is a breakdown of its electronic and mechanical characteristics. --- ### 1. General Specifications The W2CA-113-R is generally categorized as an **Actuator or Contact Unit** for heavy-duty limit switches. It is designed to bridge the mechanical movement of a machine into an electrical signal. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Contact Block / Switch Insert | | **Contact Configuration** | SPDT (Single Pole Double Throw) | | **Reset Mechanism** | Automatic Reset / Standard | | **Environmental Rating** | Often rated for IP67 (when housed) | | **Operating Temperature** | -10°C to +80°C | --- ### 2. Electronic Characteristics The internal electronic parts consist of high-conductivity contacts designed to handle industrial voltage levels without welding or excessive arcing. * **Contact Material:** Usually silver or gold-clad silver to ensure low contact resistance and long life cycles. * **Voltage Rating:** Typically supports up to **250V AC** or **125V DC**, depending on the specific housing it is installed in. * **Current Rating:** Usually rated for **10A** (resistive load) at 125/250VAC. * **Insulation Resistance:** 100 MΩ min. (at 500 VDC). --- ### 3. Application and Usage This part is used as a sub-component within a larger limit switch assembly (like the WL or WLM series). It serves the following functions: 1. **Position Sensing:** Detecting the presence or absence of an object in automated lines. 2. **Safety Interlocking:** Preventing a machine from starting unless a guard is closed. 3. **End-of-Travel Detection:** Stopping a motor when a mechanical arm reaches its maximum limit. --- ### 4. Terminal Identification The "R" in the suffix often denotes a specific terminal orientation or a reinforced design for vibration resistance. * **COM (Common):** The input terminal. * **NC (Normally Closed):** The circuit is closed when the switch is at rest. * **NO (Normally Open):** The circuit closes only when the actuator is triggered. ---
