The **W2TS-22B-R/Q** is a specific model of an industrial **LED Pilot Light (Indicator)**. These components are essential in control panels, automation systems, and machinery to provide visual status feedback to operators. Below is a breakdown of its electronic and physical characteristics. --- ### 1. Technical Specifications The "W2TS" series generally follows standard industrial indicator configurations. | Feature | Specification Details | | :--- | :--- | | **Component Type** | LED Indicator / Pilot Light | | **Mounting Diameter** | 22mm (Standard industrial cutout) | | **Light Source** | High-intensity LED | | **Color** | **Red** (Indicated by the "R" in the suffix) | | **Lens Shape** | Round/Domed Flush type | | **Operating Voltage** | Typically 24V AC/DC or 110V/220V AC (Verify via specific label) | | **Protection Rating** | Usually IP65 (Dust-tight and water-resistant) | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps identify the exact electronic requirements: * **W2TS**: The series designation (Often associated with brands like *Widmuller* or generic industrial manufacturers using this naming convention). * **22**: Refers to the **22mm** mounting hole diameter required on the control panel. * **B**: Often designates the body style or terminal type (e.g., screw terminals). * **R**: Indicates the color **Red**. Red is typically used for "Emergency," "Stop," or "Fault" conditions. * **Q**: Usually indicates the voltage or specific LED driver type (e.g., 24V AC/DC integrated circuit). --- ### 3. Electronic Design & Features #### A. Internal Circuitry Unlike old incandescent bulbs, this part uses an **LED module**. Internally, it contains: * **Current Limiting Resistors:** To prevent the LED from burning out. * **Bridge Rectifier (Optional):** If the unit is rated for "AC/DC," it contains a small diode bridge to allow the light to function regardless of polarity. * **Leakage Current Protection:** High-quality units include circuitry to prevent the LED from glowing faintly due to induced voltage in long cable runs. #### B. Connection Interface The back of the unit features **Screw Terminals**. These are designed for: * Standard industrial wiring (14–22 AWG). * Easy integration into a PLC (Programmable Logic Controller) output loop. --- ### 4. Typical Applications The W2TS-22B-R/Q is commonly found in: * **Control Panels:** To indicate that a machine has stopped or failed. * **Safety Circuits:** Linked to E-Stop buttons to show a tripped state. * **Power Distribution:** To indicate the presence of a specific phase or power state.
