The **KADS-EC-R/Q** series typically refers to industrial-grade limit switches or sensor components often used in safety systems, elevators, or automated machinery. Below is an explanation of its electronic and electromechanical parts. --- ### 1. General Specifications These components are designed for high reliability in harsh environments. The "R" and "Q" suffixes usually denote specific mounting styles or contact configurations. | Component Feature | Description | | :--- | :--- | | **Contact Type** | Typically Silver Alloy (Ag) contacts for high conductivity. | | **Housing Material** | Reinforced plastic or die-cast aluminum (depending on the model). | | **Protection Rating** | Usually IP65 or IP67 (dust-tight and water-resistant). | | **Switching Logic** | Snap-action or Slow-action (NC/NO configurations). | ### 2. Key Electronic & Mechanical Parts #### A. Contact Blocks The internal switching mechanism consists of: * **Normally Closed (NC) Contacts:** Used for safety "stop" circuits. * **Normally Open (NO) Contacts:** Used for signaling or "start" triggers. * **Bifurcated Contacts:** Some high-end versions use split contacts to ensure reliability even under low-voltage/low-current conditions (logic level). #### B. Actuator Head This is the mechanical interface that triggers the internal electronic state: * **Plunger/Roller:** Converts physical movement into electrical signals. * **Return Spring:** Ensures the contacts return to their original state once the force is removed. #### C. Terminals * **Screw Terminals:** Standard for industrial wiring, allowing for secure connection of 14-22 AWG wires. * **Galvanic Isolation:** The internal structure ensures that separate poles are electrically isolated from one another to prevent short circuits. ### 3. Electrical Ratings (Standard Example) While specific data depends on the exact manufacturer (often related to brands like Kacon or similar industrial suppliers), typical ratings are: ```yaml Electrical_Parameters: Rated_Voltage: 250V AC / 125V DC Rated_Current: 5A to 10A (Resistive Load) Insulation_Resistance: 100MΩ min (at 500V DC) Dielectric_Strength: 2,500V AC (for 1 minute) Contact_Resistance: 25mΩ max (initial) ``` --- ### 4. Application Context The **KADS-EC** series is frequently utilized in: 1. **Safety Interlocks:** Ensuring a machine guard is closed before power is applied. 2. **Position Detection:** Detecting the arrival of a lift or conveyor tray. 3. **End-of-Travel Limits:** Cutting power to a motor when a mechanical arm reaches its maximum boundary. ---
