The **W2TS-N2A-R2/N** appears to be a specific model part number, commonly associated with **Wenglor** sensor technology or industrial automation components (specifically from their temperature or flow sensor series). Below is a breakdown of the electronic components and technical specifications typical for this class of industrial sensors. --- ### 1. Technical Specifications The part number follows a modular nomenclature representing its electrical and mechanical configuration. | Feature | Specification Details | | :--- | :--- | | **Sensor Type** | Thermal Flow or Temperature Sensor | | **Operating Voltage** | Typically 10...30 V DC | | **Output Type** | PNP (Push-Pull) / Analog (4-20mA or 0-10V) | | **Switching Output** | Normally Open (NO) / Normally Closed (NC) selectable | | **Connector Type** | M12 × 1, 4-pin | | **Pressure Range** | Up to 100 Bar (depending on housing) | | **Protection Class** | IP67 / IP68 (Dust and Water resistant) | --- ### 2. Internal Electronic Components The device is comprised of several high-precision electronic stages to ensure accuracy in industrial environments: * **Sensing Element:** Usually a PT100 or PT1000 Platinum Resistance Temperature Detector (RTD) integrated into the probe tip. * **Signal Conditioner:** An internal Operational Amplifier (Op-Amp) circuit that converts the minute resistance changes of the RTD into a stable voltage. * **Microcontroller (MCU):** Processes the analog data, handles the logic for the switching outputs, and manages the LED status indicators. * **Output Driver:** A robust transistor-based stage (PNP/NPN) designed to handle short circuits and inductive loads. * **EMC Protection:** Integrated varistors and capacitors to protect the internal circuitry from electromagnetic interference and voltage spikes common in factory settings. --- ### 3. Wiring and Connection (M12 Layout) To integrate this electronic part into a PLC (Programmable Logic Controller), the following standard pinout is generally used: ```markdown Pin 1: Brown (+) -> L+ (10-30V DC) Pin 2: White (A) -> Analog Output / Configuration Pin 3: Blue (-) -> M (0V / Ground) Pin 4: Black (S) -> Switching Output (PNP/NPN) ``` --- ### 4. Key Features * **IO-Link Compatibility:** Many "W2TS" models support IO-Link for digital parameter setting and diagnostics. * **Stainless Steel Housing:** The electronics are encased in V4A (1.4404) stainless steel to prevent corrosion. * **Status LEDs:** Integrated visual feedback for power supply and switching state. ---
