The **M2VF2-36-R/Q** is a high-precision, industrial-grade linear displacement transducer (often referred to as a LVDT or magnetostrictive sensor depending on the specific series architecture). It is commonly used in hydraulic cylinders and heavy machinery to measure exact positioning. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Model Series** | M2 (High-performance displacement) | | **Effective Stroke** | 36 Inches (Approx. 914.4 mm) | | **Output Type** | Voltage (V) - Typically 0-10V or 10-0V | | **Mounting Style** | F2 (Standard flange or thread mount) | | **Protection Class** | IP67 / IP68 (Depending on seal configuration) | | **Linearity** | < ±0.01% of full scale | | **Resolution** | Infinite (Analog) or 16-bit (Digital internal) | --- ### 2. Key Electronic Components The device operates using **Magnetostrictive Technology**, which involves several internal electronic sub-systems: #### A. The Waveguide The core sensing element is a ferromagnetic wire (waveguide). An internal electronic pulse generator sends a "start" pulse down this wire. #### B. The Position Magnet A permanent magnet is attached to the moving part of the machine. When the start pulse reaches the magnetic field of this magnet, a mechanical strain wave (torsional pulse) is triggered and travels back toward the sensor head. #### C. The Pickup / Signal Converter * **Strain Sensor:** At the head of the unit, a specialized coil detects the returning mechanical wave. * **Microprocessor:** Measures the time interval between the "start" pulse and the "return" pulse. Since the speed of sound in the waveguide is constant, the time is converted into a highly accurate distance measurement. #### D. Output Driver (R/Q) * **The "R" Suffix:** Often denotes a specific connector type (e.g., M12 or 6-pin circular). * **The "Q" Suffix:** Usually indicates a specific voltage output range (e.g., 0-10 VDC) or a specific diagnostic feature. --- ### 3. Connection and Wiring Most models in this series utilize a standard industrial pinout for integration with PLCs (Programmable Logic Controllers): ```yaml Pin 1: +24 VDC (Power Supply) Pin 2: Output Signal (0-10V) Pin 3: 0V (Ground) Pin 4: Signal Return / Shield ``` --- ### 4. Common Applications * **Hydraulic Cylinders:** Monitoring piston position in real-time. * **Injection Molding:** Controlling the stroke of the clamp or injector. * **Woodworking/Steel Mills:** Precise cutting and positioning of heavy materials.
