The **GLP2-100-R-54** is a specialized electronic component typically associated with high-precision linear displacement sensing or industrial automation. Based on its nomenclature, it belongs to a series of linear potentiometers (or displacement transducers). ### Technical Specifications Overview | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Linear Potentiometer / Displacement Transducer | | **Measurement Stroke** | 100 mm | | **Mounting Style** | Pivot Heads (Rod Ends) - indicated by the "R" | | **Protection Class** | IP54 (Dust and splash water protected) | | **Resistance Tolerance** | ±20% | | **Linearity** | ±0.05% to ±0.1% | | **Operating Temperature** | -30°C to +100°C | --- ### Key Electronic & Mechanical Parts #### 1. Conductive Plastic Element The core electronic part is a high-quality **conductive plastic resistive track**. Unlike wire-wound potentiometers, conductive plastic offers: * **Infinite Resolution:** Smooth voltage transition. * **Long Life:** Capable of millions of cycles due to low friction. #### 2. Wiper System The internal "wiper" is a multi-finger precious metal contact. It slides along the resistive track to provide a ratiometric voltage output. The multi-finger design ensures stable electrical contact even under high vibration. #### 3. The "R" Configuration (Rod Ends) The "R" in the part number signifies **Rod Eye/Pivot Head** mountings. These are mechanical joints at both ends of the sensor that allow for: * Self-alignment during movement. * Compensation for slight non-linearities or "wobble" in the machinery it is measuring. #### 4. Housing and Protection (IP54) The "54" at the end of the code refers to the **Ingress Protection** rating: * **5:** Protected against limited dust ingress. * **4:** Protected against water splashes from any direction. The outer casing is usually anodized aluminum to protect the internal electronic track from electromagnetic interference (EMI). --- ### Electrical Connections Most GLP2 series sensors use a standard 3-wire configuration: | Pin/Wire Color | Function | Description | | :--- | :--- | :--- | | **Brown (1)** | Input + | Excitation Voltage (e.g., 5V or 10V DC) | | **Blue (2)** | Output | Variable voltage signal proportional to position | | **Black (3)** | Ground - | Common return | --- ### Common Applications * **Industrial Machinery:** Monitoring the position of hydraulic cylinders. * **Automotive Testing:** Measuring suspension travel or throttle position. * **Robotics:** Feedback loops for linear actuators. ---
