Based on the technical nomenclature for industrial control components, the **W2TS-1BB-R/N** typically refers to a **22mm Industrial Pushbutton Switch**, often associated with brands like **Tend** or similar manufacturers specializing in control panel components. --- ### 1. General Specifications The W2TS series consists of modular industrial switches designed for durability and ease of installation in control cabinets. | Parameter | Specification | | :--- | :--- | | **Mounting Diameter** | 22mm (Standard) | | **Action Type** | Momentary (Spring Return) | | **Operator Shape** | Extended / Flush Round Head | | **Illumination** | Non-Illuminated (standard for this suffix) | | **Color Code** | R (Red) / N (Black/Neutral - depending on manufacturer catalog) | --- ### 2. Breakdown of the Model Name The alphanumeric code identifies specific mechanical and electrical properties: * **W2TS**: The series identifier (22mm diameter pilot devices). * **1BB**: Indicates the contact block configuration. Usually, this signifies **1 Normally Closed (NC)** or **1 Normally Open (NO)** contact, depending on the specific block assembly attached. * **R/N**: * **R**: Red button cap (often used for Stop or Reset). * **N**: Represents the color Black or a specific housing variation. --- ### 3. Electrical Characteristics These parts are designed for low-voltage control circuits (AC-15 or DC-13 categories). * **Rated Insulation Voltage (Ui):** 600V * **Thermal Current (Ith):** 10A * **Contact Resistance:** $\le 50m\Omega$ * **Mechanical Life:** $> 1,000,000$ operations * **Electrical Life:** $> 500,000$ operations at full load --- ### 4. Connection and Installation 1. **Terminal Type:** Screw terminals with pressure plates (compatible with ring or fork lugs). 2. **Mounting:** The head is inserted through a 22.5mm hole, and a locking ring secures it from the back. The contact blocks are then snapped onto the back of the actuator. 3. **Ingress Protection:** Usually rated **IP65**, making it resistant to dust and water splashes from all directions. --- ### 5. Application Usage * **Emergency Stop circuits:** (If the head is mushroom-style, though W2TS is usually standard push). * **Motor Starters:** Used to trigger contactors. * **PLC Inputs:** Providing human-to-machine interface signals.
