The **M2TS-1D-R2/CE** is a high-precision digital contact displacement sensor (often referred to as a digital gauge or pencil probe) manufactured by **Magnescale** (formerly Sony Precision Technology). Below is a breakdown of its electronic components, technical specifications, and interface characteristics. --- ### 1. Core Technical Specifications The device operates on the principle of magnetic induction/detection, which provides high resistance to oil, water, and shop-floor contaminants compared to optical sensors. | Feature | Specification | | :--- | :--- | | **Measuring Range** | 12 mm | | **Resolution** | 0.1 $\mu$m (depending on the interpolator/counter) | | **Accuracy** | 2.0 $\mu$m (peak-to-peak) | | **Interface** | RS-232C (via specific interface units) | | **Protection Class** | IP67 (Dust-tight and water-resistant) | | **Measuring Force** | Approx. 1.3 N (Downward) | --- ### 2. Electronic Component Breakdown #### A. The Magnetic Scale Technology Unlike resistive potentiometers, the M2TS series uses a **magnetic scale** embedded within the spindle. * **Scale Rod:** A rod with magnetic patterns is built into the moving spindle. * **Detection Head:** A multi-gap magnetic head detects the change in magnetic flux as the spindle moves. * **Signal Type:** It typically outputs a high-resolution analog sine/cosine wave internally, which is then digitized. #### B. Signal Processing & Connectivity The "R2" designation specifically refers to its integration capabilities with RS-232C communication protocols when used with Magnescale's network modules. * **Integrated Circuitry:** The probe tail contains micro-electronics for signal conditioning to ensure low noise over the cable length. * **Connection Port:** It usually features a mini-DIN or specialized circular connector designed to plug into a **MG series** (Main Unit) or **LZ series** display. #### C. Power Requirements * **Input Voltage:** Typically powered via the interface unit (approx. 5V DC). * **Power Consumption:** Extremely low, allowing for multi-point measurement arrays without heavy power draws. --- ### 3. Usage Environment The "CE" marking indicates compliance with European safety, health, and environmental protection standards. The electronics are shielded against: 1. **EMC (Electromagnetic Compatibility):** Minimal interference from nearby industrial motors. 2. **ESD (Electrostatic Discharge):** Protection against static buildup from moving mechanical parts. --- ### 4.
