The **RBS-16-R** is an electronic component primarily classified as a **Tilt Switch** or **Ball-Rolling Sensor**. It is designed to detect changes in orientation or mechanical movement without the use of hazardous substances like mercury. --- ### 1. Technical Specifications The RBS-16-R is a non-mercury, vibration-sensitive switch. Below are its typical electrical and physical characteristics: | Property | Specification | | :--- | :--- | | **Contact Type** | Normally Open (NO) / Triggered by tilt | | **Switching Voltage** | 5V - 12V DC (Max depends on manufacturer) | | **Switching Current** | 10mA - 20mA | | **Operating Angle** | ~15° to 45° (Tilt sensitivity) | | **Housing Material** | High-performance plastic / PBT | | **Internal Mechanism** | Metallic ball-contact system | --- ### 2. How it Works The internal structure consists of a conductive ball and two contact pins. * **Horizontal Position:** When the sensor is level, the ball remains away from the contacts, and the circuit is **Open**. * **Tilted Position:** When the device is tilted past a certain angle, the metal ball rolls toward the pins, bridging them and making the circuit **Closed**. * **Omni-directional:** Most versions of this series are sensitive to tilting in multiple directions. --- ### 3. Key Features 1. **RoHS Compliant:** Unlike older "mercury switches," the RBS-16-R uses a solid metal ball, making it environmentally safe. 2. **Durability:** It is usually sealed to prevent oxidation of the internal contacts, ensuring a long lifecycle. 3. **Simplicity:** It acts as a passive digital switch, meaning it does not require complex signal processing to detect a state change. --- ### 4. Application Examples The RBS-16-R is commonly found in consumer electronics and safety devices: * **Anti-Tip Protection:** Used in space heaters or fans to automatically shut off power if the device falls over. * **Alarm Systems:** Detecting when a window or door is being tampered with. * **Screen Rotation:** Simple triggers for rotating displays in toys or handheld gadgets. * **Vibration Sensing:** Detecting if a machine is moving or shaking excessively. --- ### 5. Implementation (Basic Example) To use this with a microcontroller like an Arduino, you treat it like a standard pushbutton with a pull-up resistor. ```cpp const int sensorPin = 2; // Connected to RBS-16-R void setup() { pinMode(sensorPin, INPUT_PULLUP); Serial.begin(9600); } void loop() { int sensorState = digitalRead(sensorPin); if (sensorState == LOW) { Serial.println("Device Tilted!"); } } ```
