The **JS350-R** typically refers to a high-torque, industrial-grade linear actuator (often used in ergonomic desks, medical beds, or industrial automation). The electronic components of this system are divided between the **Actuator Unit** itself and the **Control Box** that manages it. --- ### 1. Actuator Internal Components The mechanical movement is driven by these core electronic parts located inside the JS350-R housing: | Component | Function | | :--- | :--- | | **DC Motor** | Usually a 24V or 12V Permanent Magnet motor that converts electrical energy into rotational force. | | **Hall Effect Sensors** | Dual sensors that provide pulse feedback to the controller to track position, speed, and synchronization. | | **Limit Switches** | Internal micro-switches that cut power or signal the controller when the actuator reaches its maximum extension or retraction. | | **Wiring Harness** | A 6-pin or 8-pin DIN/Molex connector carrying power for the motor and low-voltage signals for the sensors. | --- ### 2. Control System & Drive Electronics The JS350-R cannot function alone; it requires a control box (e.g., JCB35N series) which contains: * **H-Bridge Circuitry:** A set of power transistors (MOSFETs) that reverse the polarity of the current to change the motor's direction (Up vs. Down). * **Microcontroller (MCU):** The "brain" that counts pulses from the Hall sensors to ensure the legs move perfectly in sync (to prevent tilting). * **SMPS (Switched-Mode Power Supply):** Converts AC wall power (110V/220V) into the stable DC voltage required by the actuator. * **Overload Protection:** A current-sensing resistor that shuts down the system if it detects a spike in amperage (indicating an obstruction or weight limit breach). --- ### 3. Technical Specifications (Electronic) The electronic performance is generally defined by the following parameters: ```json { "Input_Voltage": "24V DC", "Current_Rating": "5A - 8A (Typical under load)", "Feedback_Type": "Hall Sensor (Double Hall for sync)", "Duty_Cycle": "10% (2 min on / 18 min off)", "Protection_Class": "IP54 or IP66" } ``` --- ### 4. Connection Pinout While variations exist, a standard JS350-R electronic interface uses a 6-pin connector: 1. **Motor + / -** (Power) 2. **Motor - / +** (Power) 3. **VCC** (5V for Sensors) 4. **GND** (Ground for Sensors) 5. **Hall Signal 1** (Pulse) 6. **Hall Signal 2** (Pulse)
