The **LS-12-R** typically refers to a high-performance **Linear Actuator** (often from the L12 series or similar industrial classes) or a specific **Limit Switch** component depending on the manufacturer. Given the part number format, it most commonly refers to a **Micro Linear Actuator** with an internal potentiometer for position feedback. Below is the breakdown of its electronic characteristics and specifications. --- ### 1. Key Electronic Components A device like the LS-12-R (specifically the "R" suffix version) usually contains several integrated electronic subsystems: | Component | Function | | :--- | :--- | | **DC Brushed Motor** | Converts electrical energy into rotary motion to drive the lead screw. | | **Feedback Potentiometer** | A resistive element that provides an analog voltage signal corresponding to the stroke position. | | **Wiper Assembly** | Moves along the resistive track to change the resistance value. | | **Internal Limit Switches** | (In some models) Automatically cuts power at the end of the stroke to prevent motor burnout. | --- ### 2. Technical Specifications Most units under this nomenclature operate within the following electrical parameters: | Parameter | Typical Value | | :--- | :--- | | **Input Voltage** | 6V DC or 12V DC | | **Feedback Type** | Analog Potentiometer (0 - 10kΩ typical) | | **Peak Current** | 450mA - 600mA (under full load) | | **Interface/Connector** | 5-wire (2 for motor power, 3 for potentiometer) | | **Stroke Accuracy** | ± 0.2mm | --- ### 3. Wiring Configuration (5-Wire Interface) The "R" variant is often a "Remote" or "Feedback" model requiring an external controller (like an Arduino or RC Receiver). The wiring typically follows this logic: 1. **Motor V+**: Power for the motor (positive for extension). 2. **Motor V-**: Power for the motor (negative for extension). 3. **Potentiometer High**: Connected to the reference voltage (e.g., 5V). 4. **Potentiometer Wiper**: The signal output (Analog voltage indicating position). 5. **Potentiometer Low**: Connected to Ground (GND). --- ### 4. Comparison of "R" vs. Other Suffixes In the context of micro-actuators: * **-S:** Features internal limit switches; simple 2-wire control (no feedback). * **-P:** Potentiometer feedback; requires external logic to stop the motor. * **-R:** Often indicates **RC Servo compatibility** or a specific high-resistance feedback loop designed for radio control systems. ---
