Key Technical Specifications Below are the primary electrical and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Precision Limit Switch / Micro Switch | | **Contact Configuration** | Single Pole, Double Throw (SPDT) | | **Rated Voltage** | Typically up to 250V AC / 30V DC | | **Rated Current** | 5A to 10A (Depending on load type) | | **Actuator Type** | Roller Lever or Plunger (Model specific) | | **Protection Rating** | IP67 (Waterproof and Dustproof) | | **Termination** | Pre-wired or Connector-based (CE standard) | --- ### 2. Core Electronic Components The internal construction of the W2CE-5B4-R2/CE consists of several critical parts: * **Switching Mechanism:** A "snap-action" spring mechanism that ensures rapid movement of contacts, minimizing arcing and increasing electrical life. * **Contacts:** Usually made of silver alloy to provide high conductivity and resistance to oxidation. * **Housing:** A ruggedized, die-cast aluminum or reinforced plastic shell designed to shield the internal electronics from electromagnetic interference (EMI) and physical impact. * **Sealing Gaskets:** Silicone or NBR rubber seals that prevent oil, water, or coolants from entering the electronic chamber. --- ### 3. Application Use Cases This part is commonly integrated into the following systems: 1. **CNC Machinery:** For detecting the home position or end-of-travel limits of moving axes. 2. **Conveyor Systems:** To sense the presence of objects or to trigger sorting gates. 3. **Safety Interlocks:** Ensuring that protective doors are closed before a machine begins operation. 4. **Robotic Arms:** Providing feedback on the physical orientation of joints. --- ### 4. Installation & Safety * **Mounting:** Ensure the actuator is aligned with the target to avoid excessive side-loading, which can wear out the internal mechanical spring. * **Wiring:** Follow the pin-out diagram on the casing to ensure the COM (Common), NO (Normally Open), and NC (Normally Closed) terminals are connected correctly for your logic circuit.
