The **W2CE-1CB-R2** is a specialized electronic component commonly used in precision sensing and measurement applications. It is part of a series of non-contact displacement sensors or proximity sensors, often associated with industrial automation and metrology. ### 1. Component Overview This part is typically classified as an **Eddy Current Sensor Probe** or a high-precision inductive sensor. It is designed to measure the distance between the probe head and a conductive (metallic) target without physical contact. ### 2. Technical Specifications The table below outlines the general characteristics of the W2CE series: | Parameter | Specification (Typical) | | :--- | :--- | | **Sensor Type** | Eddy Current (Inductive) | | **Target Material** | Conductive metals (e.g., steel, aluminum) | | **Measurement Range** | Small-scale (micrometers to millimeters) | | **Output Type** | Analog Voltage or Current (depending on controller) | | **Operating Temp** | -10°C to +60°C (standard industrial range) | | **Protection Rating** | Often IP67 (dust and water-resistant) | --- ### 3. Electronic Principles of Operation The W2CE-1CB-R2 operates based on the **Eddy Current Principle**: 1. **Oscillation**: The controller sends an alternating current through the coil inside the sensor head. 2. **Magnetic Field**: This current generates an oscillating magnetic field around the probe tip. 3. **Eddy Currents**: When a metallic target enters this field, "eddy currents" are induced on the surface of the target. 4. **Feedback**: These induced currents create their own magnetic field that opposes the probe's field, changing the impedance of the coil. 5. **Signal Conversion**: The electronic controller detects this change in impedance and converts it into a linear displacement signal (voltage or current). ### 4. Application Areas * **Vibration Analysis**: Measuring the vibration of high-speed rotating shafts. * **Gap Control**: Maintaining precise spacing in printing or coating processes. * **Thickness Gauging**: Measuring the thickness of metal sheets on a conveyor. * **Positioning**: High-precision alignment in semiconductor manufacturing. --- ### 5. Part Number Breakdown (W2CE-1CB-R2) While specific to the manufacturer's nomenclature (often related to brands like Kaman or similar metrology firms), the suffix usually denotes: * **1CB**: Refers to the physical housing size and cable length (e.g., 1 meter). * **R2**: Usually indicates a revision number or a specific sensitivity calibration for certain metals.
