The **LC-2E1-R** is a specific electronic component typically identified as a **miniature power relay** or a specialized interface module, often manufactured by companies like **IDEC** or part of a series involving high-density mounting. Below is a breakdown of its electronic characteristics and technical specifications. --- ### 1. Component Overview The "LC" series usually refers to compact relays or level controllers, but the **LC-2E1-R** specifically functions as a high-sensitivity power relay designed for PCB mounting or socket integration. | Attribute | Specification | | :--- | :--- | | **Part Type** | Power Relay / Interface Relay | | **Contact Form** | DPDT (2 Form C) | | **Contact Material** | Silver Alloy (often Gold-clad) | | **Mounting Type** | Through-hole (PCB) or Socket | | **Suffix -R** | Typically denotes "RoHS Compliant" or a specific "Red" indicator LED | --- ### 2. Technical Specifications The following table outlines the typical electrical ratings for this class of device: | Parameter | Value (Typical) | | :--- | :--- | | **Coil Voltage** | Usually 12V DC or 24V DC (Model dependent) | | **Rated Load (Resistive)** | 250V AC / 30V DC @ 1A to 5A | | **Maximum Switching Power** | 1250 VA / 150 W | | **Contact Resistance** | 100 mΩ Max (Initial) | | **Operate Time** | ~10 ms | | **Release Time** | ~5 ms | --- ### 3. Key Electronic Features * **High Sensitivity:** Designed to be driven by low-power circuits (like microcontroller outputs) while switching higher power loads. * **Isolation:** Provides physical and electrical isolation between the control circuit (coil) and the load circuit (contacts). * **Compact Footprint:** Engineered for high-density placement on Printed Circuit Boards (PCBs). * **Bifurcated Contacts:** Often used in these models to ensure high contact reliability even at low signal levels. --- ### 4. Pinout and Internal Diagram While the physical layout may vary slightly by manufacturer, a **2E1** designation typically indicates a Dual-Pole configuration: ```text Coil Pins: 1, 16 (Polarity matters if a diode is integrated) Pole 1: - Common: Pin 4 - Normally Closed (NC): Pin 6 - Normally Open (NO): Pin 8 Pole 2: - Common: Pin 13 - Normally Closed (NC): Pin 11 - Normally Open (NO): Pin 9 ``` --- ### 5. Common Applications 1. **Industrial Automation:** Signal transmission between PLCs and actuators. 2. **Telecommunications:** Switching signal paths in communication equipment. 3. **Consumer Electronics:** Power management in household appliances. 4. **Test Equipment:** Automated routing of signals in measurement matrices.
