The **W2CE-5DD-R2/N** is a specific model of an **Industrial Limit Switch** (specifically a compact, heavy-duty safety switch) manufactured by **Azbil (formerly Yamatake)**. It is widely used in factory automation to detect the position of machinery parts or objects. Below is a detailed breakdown of its specifications and electrical characteristics. ### 1. Key Technical Specifications | Feature | Specification Details | | :--- | :--- | | **Manufacturer** | Azbil Corporation | | **Actuator Type** | Roller Lever (Adjustable/Compact) | | **Circuit Configuration** | 1NC / 1NO (Single Pole Double Throw - SPDT) | | **Contact Material** | Gold-clad Silver | | **Protection Rating** | IP67 (Dust-tight and Water immersion resistant) | | **Operating Temp** | -10°C to +70°C | | **Housing Material** | Die-cast Aluminum | --- ### 2. Electrical Ratings These parts are designed for low-to-medium power control circuits. The "/N" suffix often indicates specific wiring or connector variations (typically a pre-wired or connectorized version for quick installation). | Load Type | Rated Voltage | Rated Current | | :--- | :--- | :--- | | **AC (Resistive)** | 125V / 250V | 5A | | **DC (Resistive)** | 30V | 5A | | **Minimum Load** | 5V DC | 1mA (suitable for PLC inputs) | --- ### 3. Component Breakdown #### A. The Actuator (Roller Lever) The **W2CE** series features a mechanical lever with a roller. When a physical object pushes against the roller, it rotates the internal shaft to trigger the electrical contacts. #### B. The Contact Block Inside the switch is a precision snap-action mechanism. * **NC (Normally Closed):** Breaks the circuit when the lever is pushed. * **NO (Normally Open):** Closes the circuit when the lever is pushed. #### C. Connector / Wiring The **R2** in the part number often refers to the specific exit type of the cable or the connector style (usually a specialized industrial connector or a specific cable length). This ensures the electrical signal is transmitted reliably back to a PLC (Programmable Logic Controller). --- ### 4. Typical Applications * **Conveyor Systems:** Detecting the arrival or position of a pallet. * **Machine Tools:** Sensing the home position of a sliding axis. * **Safety Interlocks:** Ensuring a guard door is closed before a machine starts. ---
