Based on the part number provided, **W2CE-5D2-R2/CE**, this component belongs to the **W2CE series** of industrial Limit Switches (often associated with brands like Moujen or similar industrial automation manufacturers). These are compact, precision-built switches used for position sensing and safety interlocks. --- ### 1. Component Overview The W2CE-5D2-R2/CE is a **Miniature Limit Switch** designed for tight spaces where high durability and environmental resistance are required. ### 2. Technical Specifications The breakdown of the technical attributes is summarized in the table below: | Feature | Specification | | :--- | :--- | | **Switch Type** | Precision Limit Switch | | **Actuator Type** | Cross Roller Plunger (R2) | | **Contact Configuration** | 1NO + 1NC (Single Pole Double Throw - SPDT) | | **Electrical Rating** | 5A at 250VAC / 0.4A at 115VDC | | **Protection Rating** | IP67 (Dust-tight, waterproof) | | **Housing Material** | Zinc Die-cast body | | **Connection Type** | Pre-wired (M12 connector or lead wire depending on sub-variant) | --- ### 3. Key Electronic Characteristics * **Snap-Action Mechanism:** This part utilizes a snap-action internal switch. This ensures that the transition between "Open" and "Closed" states happens at a constant speed, regardless of how fast the actuator is being pressed, reducing electrical arcing. * **Gold-Plated Contacts (Optional/Series standard):** Many W2CE models feature gold-cladded crossbar contacts, making them suitable for switching low-level "logic" signals (low voltage/current) without oxidation issues. * **Insulation Resistance:** Typically rated at **100 MΩ min.** (at 500 VDC), ensuring safety between the current-carrying parts and the metal housing. * **Dielectric Strength:** Usually rated for **1,000 VAC** (50/60 Hz for 1 minute) between non-continuous terminals. --- ### 4. Part Number Breakdown The suffixing follows a specific logic: 1. **W2CE**: Series Name (Miniature Limit Switch). 2. **5**: Electrical rating code (Standard current). 3. **D2**: Housing/Mounting style. 4. **R2**: Actuator style (**Cross Roller Plunger** – used for cams or slides moving perpendicular to the switch). 5. **/CE**: Certification mark indicating compliance with European Health, Safety, and Environmental standards. --- ### 5. Common Applications * **CNC Machinery:** Sensing the "Home" or "Limit" position of a moving axis. * **Conveyor Systems:** Detecting the presence or passage of items. * **Packaging Equipment:** Monitoring door interlocks or mechanical arms. ---
