The **JDL-A36-R** is a specific model of an electronic component typically categorized as a **Limit Switch** or a **Micro Switch**, often found in industrial machinery, elevators, or automated production lines. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The JDL-A36-R is designed to convert mechanical motion into an electrical signal. It is usually a "Heavy Duty" or "Industrial" grade switch. | Feature | Specification (Typical) | | :--- | :--- | | **Switch Type** | Limit Switch / Micro Switch | | **Contact Configuration** | 1NO + 1NC (1 Normally Open + 1 Normally Closed) | | **Rated Voltage** | 250V AC / 115V DC | | **Thermal Current ($I_{th}$)** | 10A | | **Actuator Type** | Roller Plunger / Roller Lever (depending on sub-variant) | | **Housing Material** | Aluminum Die-cast or Flame-retardant Plastic | --- ### 2. Internal Electronic Parts The device consists of several critical internal components that ensure reliable electrical switching: * **Contacts:** Usually made of silver alloy to provide high conductivity and resistance to electrical arcing. * **Terminal Screws:** Heavy-duty M3 or M4 screws for secure wiring of the NC (Normally Closed) and NO (Normally Open) circuits. * **Snap-action Mechanism:** A spring-loaded internal leaf spring that ensures a rapid transition between states to prevent "teasing" the contact, which reduces electrical wear. * **Insulation:** High-grade phenolic or ceramic insulators to prevent short-circuiting between the poles and the metallic casing. --- ### 3. Connection Diagram The electrical wiring usually follows a standard industrial numbering system: ```text Terminal 1-2: NC (Normally Closed) - Circuit is ON until pressed. Terminal 3-4: NO (Normally Open) - Circuit is OFF until pressed. ``` --- ### 4. Applications The JDL-A36-R is commonly used in the following electronic systems: 1. **Safety Interlocks:** Ensuring a machine door is closed before the circuit completes. 2. **Position Detection:** Stopping a motor when a mechanical arm reaches its limit. 3. **Conveyor Systems:** Counting items or detecting jams on a production line.
