The **18KTS-06A-R** is a high-performance **Micro-Solenoid Valve**, typically used in medical devices, portable monitors, and automated equipment for fluid or gas control. --- ### 1. Technical Specifications The following table highlights the core electronic and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Component Type** | Solenoid Valve (Micro-Electric) | | **Rated Voltage** | DC 6.0V (Commonly used in battery-operated devices) | | **Operating Current** | ~100mA - 150mA (Varies by pressure load) | | **Pressure Range** | 0 to 350 mmHg (Millimeters of Mercury) | | **Type** | Normally Open (NO) | | **Media** | Air / Non-corrosive Gases | | **Response Time** | < 3 seconds (to exhaust from 300mmHg to 15mmHg) | --- ### 2. Key Electronic Components & Working Principle The 18KTS-06A-R operates based on electromagnetic principles: * **Electromagnetic Coil:** When DC voltage is applied, the internal copper coil generates a magnetic field. * **Plunger/Armature:** This magnetic field pulls a ferrous plunger, which overcomes a mechanical spring to change the state of the valve (closing it). * **Leakage Rate:** These valves are engineered for high precision, usually featuring a leakage rate of less than 3mmHg/min. * **Driver Circuitry:** To interface this with a microcontroller (like an Arduino or ESP32), you typically need a **transistor (MOSFET)** and a **flyback diode** to protect against inductive voltage spikes. --- ### 3. Common Applications Due to its small form factor and 6V operation, it is widely found in: 1. **Electronic Blood Pressure Monitors:** Used to control the release of air from the cuff. 2. **Massage Devices:** Controlling air pockets in pneumatic massagers. 3. **Medical Oxygen Concentrators:** Managing airflow in portable units. 4. **Laboratory Automation:** Precise gas venting. --- ### 4. Integration Example (Pseudo-Code) To control this valve using a 5V logic signal and a MOSFET: ```cpp const int valvePin = 9; // Connected to Gate of MOSFET void setup() { pinMode(valvePin, OUTPUT); } void loop() { digitalWrite(valvePin, HIGH); // Close valve (Start building pressure) delay(5000); digitalWrite(valvePin, LOW); // Open valve (Exhaust/Release air) delay(2000); } ``` ---
