The **X1-5B-R** typically refers to a high-precision, sub-miniature **Load Cell** (force sensor) often manufactured by companies like Forsentek or similar industrial sensor specialists. These components are designed for tension and compression measurement in space-constrained environments. --- ### 1. Key Electronic Specifications The performance of the X1-5B-R is defined by its electrical characteristics, which determine how it interfaces with an amplifier or controller. | Parameter | Typical Value | | :--- | :--- | | **Rated Output (Sensitivity)** | 1.0 ~ 2.0 mV/V | | **Excitation Voltage** | 3 ~ 10V DC (Standard) | | **Input Resistance** | 350 ± 30 Ω | | **Output Resistance** | 350 ± 5 Ω | | **Insulation Resistance** | ≥ 2000 MΩ (50V DC) | | **Compensated Temp. Range** | -10°C to +40°C | --- ### 2. Core Components and Construction The device is a "transducer," meaning it converts mechanical force into a measurable electrical signal. * **Strain Gauges:** The internal heart of the sensor. These are foil-based resistors bonded to the sensor body. When the body deforms, the resistance changes. * **Wheatstone Bridge Circuit:** The strain gauges are wired in a bridge configuration to provide a differential voltage output, ensuring high accuracy and temperature compensation. * **Elastic Body:** Usually made of High-Strength Stainless Steel or Aluminum Alloy, designed to flex microscopically under load. * **Wiring/Cabling:** Typically features a 4-core shielded cable to protect the low-voltage signal from Electromagnetic Interference (EMI). --- ### 3. Wiring Diagram (Color Coding) Most X1 series sensors follow the standard industrial 4-wire color code: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Red** | Excitation + | Positive Input Power | | **Black** | Excitation - | Negative Input Power (Ground) | | **Green** | Signal + | Positive Output Signal | | **White** | Signal - | Negative Output Signal | --- ### 4. Integration Requirements To use the X1-5B-R in an electronic system, you generally need the following signal chain: 1. **Regulated Power Supply:** To provide a stable excitation voltage (usually 5V). 2. **Signal Amplifier/Transmitter:** Because the output is in millivolts (mV), it is too small for most microcontrollers (like Arduino) to read directly. An **HX711** or an industrial **Instrumentation Amplifier** is required. 3. **ADC (Analog to Digital Converter):** To convert the amplified analog signal into a digital value for processing. ---
