The **HRS-0G-R** refers to a specific series of high-performance, compact **Micro-Limit Switches** or **Detection Switches**, commonly manufactured by brands like **C&K** or **Panasonic** (depending on the specific industry suffix). These are primarily used for position detection in consumer electronics and industrial automation. --- ### ## Technical Specifications The "HRS" series is characterized by its miniature footprint and high reliability. Below are the typical electronic characteristics for the **HRS-0G-R** model: | Parameter | Value / Range | | :--- | :--- | | **Contact Rating** | 1mA 5V DC to 100mA 30V DC | | **Contact Resistance** | < 100 mΩ (Initial) | | **Insulation Resistance** | > 100 MΩ (at 100V DC) | | **Dielectric Strength** | 100V AC for 1 minute | | **Operating Force** | 50gf to 100gf (approx. 0.5N to 1N) | | **Mechanical Life** | 50,000 to 100,000 cycles | | **Circuitry** | SPST (Normally Open or Normally Closed) | --- ### ### Key Internal Components The electronic functionality of the HRS-0G-R relies on several precision-engineered parts: 1. **Actuator (Lever/Button):** The external interface that physical objects press against to trigger the switch. 2. **Movable Contact:** A spring-loaded metal leaf (often copper alloy) that snaps into position when the actuator is depressed. 3. **Fixed Terminals:** The leads that are soldered onto the PCB. The "R" in the part number often denotes **Right-Angle** or a specific **Reversed** mounting orientation. 4. **Housing:** A heat-resistant thermoplastic (LCP or PBT) that protects the internal contacts from dust and moisture. --- ### ### Typical Circuit Application In most electronic designs, the HRS-0G-R acts as a "logic signal" trigger rather than a power switch. Below is a simple representation of how it is integrated into a microcontroller (MCU) circuit. ```cpp // Example: Using HRS-0G-R as a Limit Switch const int switchPin = 2; // Connected to the switch terminal void setup() { pinMode(switchPin, INPUT_PULLUP); // Use internal resistor Serial.begin(9600); } void loop() { int switchState = digitalRead(switchPin); if (switchState == LOW) { // Switch is pressed (Contact Closed) Serial.println("Object Detected!"); } } ``` --- ### ### Common Applications * **Smartphones/Tablets:** Detecting if a flip cover is closed. * **Optical Drives:** Detecting the tray position (Open/Closed). * **Industrial Sensors:** End-of-travel limits for small robotic arms. * **Medical Devices:** Presence detection for disposable cartridges.
