The **M2TS-62-R2/CE** is a high-precision, industrial-grade **Magnetostrictive Linear Position Sensor** typically manufactured by companies like Santest or similar high-end industrial automation brands. It is designed for non-contact, high-accuracy measurement of linear displacement. --- ### 1. Core Operating Principle The sensor operates on the **Magnetostrictive principle**. A torsional strain pulse is generated within a waveguide when a magnetic field from a moving magnet interacts with an internal current pulse. The time-of-flight of this pulse is measured to determine the exact position of the magnet. ### 2. Technical Specifications Below are the primary electronic and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Magnetostrictive Linear Displacement | | **Stroke Length** | 620 mm (indicated by the "62" in the model code) | | **Output Type** | Analog / Digital (R2 typically denotes specific analog or RS422 protocol) | | **Input Voltage** | +24V DC (Standard Industrial) | | **Protection Class** | IP67 (Dust tight and water immersion resistant) | | **Linearity** | < ±0.05% FS | | **Certification** | CE Marked (Compliance with EU safety/EMC standards) | --- ### 3. Key Electronic Components The internal electronics of the M2TS series consist of three main functional blocks: * **The Waveguide:** A specialized ferromagnetic wire that carries the ultrasonic strain wave. * **The Pickup Coil (Transducer):** Located at the head of the sensor, it converts the mechanical strain wave back into an electrical signal using the Villari effect. * **Signal Processing Circuitry:** * **Pulse Generator:** Sends high-speed current pulses down the waveguide. * **Timer/Counter:** A high-frequency clock that measures the nanosecond interval between the start pulse and the return pulse. * **D/A Converter:** Converts the digital timing data into a standard industrial signal (like 4-20mA or 0-10V) if configured for analog output. --- ### 4. Wiring and Interface The "R2" designation often refers to the electrical interface configuration. * **Connector Type:** Usually an M12 or M16 industrial circular connector. * **Shielding:** The sensor utilizes a ruggedized metal housing that acts as a Faraday cage to protect sensitive timing electronics from EMI (Electromagnetic Interference) common in factory environments. --- ### 5. Common Applications * **Hydraulic Cylinders:** Measuring the stroke position of the piston. * **Injection Molding:** Monitoring the clamp or injection unit position. * **Woodworking/Metalworking:** Precision positioning of saw blades or press brakes.
