The **W2CA-1BD-R** is a specific part number typically associated with **OMRON** industrial components, specifically within their range of high-performance limit switches or sensing units. It is often a component of the **WL-N** or **WLC** series, known for durability in harsh industrial environments. --- ### 1. General Specifications This part is a **sensing unit** or a **plunger-type limit switch head/body assembly**. Below are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Actuator/Sensing Unit | | **Actuator Type** | Roller Plunger (typical for the "2" designation) | | **Load Rating** | Standard Load (Usually 10A at 125/250 VAC) | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Circuitry** | 1NC / 1NO | | **Durability** | High Mechanical & Electrical Life (30M operations min) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the construction: * **W2**: Usually refers to the actuator style (Roller plunger type designed for side-thrust or vertical movement). * **CA**: Indicates the specific housing or body style (often "standard" or "compact" depending on the sub-series). * **1BD**: This refers to the **LED/Neon Indicator** or the wiring specification. * **1**: Standard contact configuration. * **B**: Often indicates a specific environment rating (e.g., oil-resistant). * **D**: Frequently denotes a **DC operating voltage** for the built-in status indicator lamp. * **R**: Generally stands for **Right-hand mounting** or a specific **Reset** functionality. --- ### 3. Electrical Characteristics If the unit includes a lamp (indicated by the 'D' in most Omron nomenclature), the electrical ratings for the indicator are as follows: ```json { "Operating_Voltage": "12 to 24V DC", "Leakage_Current": "0.5 mA max", "Indicator_Type": "LED (Red or Green)", "Insulation_Resistance": "100 MΩ min. (at 500 VDC)" } ``` --- ### 4. Application Use Cases The W2CA-1BD-R is engineered for precision and longevity. Common applications include: 1. **Positioning:** Ensuring a machine part has reached a specific coordinate. 2. **Safety Interlocking:** Preventing a machine from starting if a guard door is open. 3. **End-of-Travel Detection:** Stopping a motor or conveyor once a physical limit is reached. ---
