The **RBS-10-R** is an electronic component primarily classified as a **Tilt Switch** or **Rolling Ball Sensor**. It is designed to detect orientation or movement by using a physical ball that completes or breaks an electrical circuit when the device is tilted. --- ### 1. Technical Specifications Below are the typical technical parameters for the RBS-10-R sensor: | Feature | Specification | | :--- | :--- | | **Contact Type** | Non-Contact / Rolling Ball | | **Switching Voltage** | 5V - 12V DC (Typical) | | **Switching Current** | 10mA - 20mA (Max) | | **Sensitivity Angle** | ~10° to 45° (Depending on model variant) | | **Housing Material** | High-temperature Resistant Plastic / Metal | | **Operating Temp** | -25°C to +85°C | --- ### 2. Internal Mechanism The device operates on a simple but effective mechanical principle: 1. **The Ball:** Inside the housing is a small, conductive metal ball. 2. **The Terminals:** Two conductive pins protrude into the bottom of the internal chamber. 3. **The Trigger:** - **Horizontal Position:** The ball rests on the pins, creating a **Closed Circuit** (Conductive). - **Tilted Position:** The ball rolls away from the pins, creating an **Open Circuit** (Non-conductive). ### 3. Key Electronic Characteristics * **Omni-directional Sensing:** Many versions of the RBS-10 series are designed to trigger regardless of which direction the unit is tilted, provided it moves away from the vertical/horizontal axis. * **Debouncing Requirement:** Because a rolling ball can "bounce" or rattle against the contacts, the output signal often requires a **Software Debounce** or a **Hardware Filter** (using a capacitor) to prevent false triggering. * **Low Power Consumption:** Since it is a passive mechanical switch, it consumes zero power in a static state, making it ideal for battery-operated wake-up circuits. --- ### 4. Common Applications * **Security Systems:** Detecting if a device or container has been moved or tampered with. * **Screen Rotation:** Used in older or budget electronics to detect screen orientation. * **Safety Cut-offs:** Automatically turning off heaters or irons if they tip over to prevent fires. * **Toys/Gadgets:** Triggering lights or sounds when an object is shaken or moved. ### 5. Sample Connection (Arduino/Microcontroller) To read the state of an RBS-10-R, you typically use a pull-up resistor. ```cpp const int tiltPin = 2; // Pin connected to RBS-10-R void setup() { pinMode(tiltPin, INPUT_PULLUP); // Use internal pull-up Serial.begin(9600); } void loop() { int state = digitalRead(tiltPin); if (state == HIGH) { Serial.println("Device Tilted!"); } else { Serial.println("Device Level."); } delay(100); } ``` ---
