The **M2XM2-1Z1-R/UL** is a high-performance **Electromagnetic Relay** manufactured by **Megachips** (or often associated with specific industrial power control components). This specific part number follows a modular nomenclature standard for power relays used in automation and PCB design. ### Technical Specifications The following table outlines the typical electrical and physical characteristics of this component series: | Characteristic | Specification | | :--- | :--- | | **Contact Form** | 1Z (SPDT - Single Pole Double Throw) | | **Contact Material** | Silver Alloy (AgSnO2 or AgNi) | | **Rated Load (Resistive)** | 10A to 16A @ 250VAC / 30VDC | | **Coil Voltage** | Typically 12VDC or 24VDC (Check suffix) | | **Safety Certifications** | UL (Underwriters Laboratories) Recognized | | **Mounting Type** | PCB Mount (Through-hole) | | **RoHS Status** | Compliant (-R suffix) | --- ### Part Number Breakdown Understanding the code helps in identifying the specific functional blocks of the electronic part: * **M2X**: Series identifier (typically indicates a miniature power relay series). * **M2**: Mounting/Size classification (Standard footprint). * **1Z**: Contact configuration. "1" indicates one pole, and "Z" represents a change-over contact (Form C). * **1**: Standard sensitivity or specific coil power rating. * **R**: Environmentally friendly/RoHS compliant construction. * **UL**: Indicates the component has passed UL safety testing for the North American market. --- ### Internal Components & Operation 1. **The Coil**: When current flows through the copper coil, it creates an electromagnetic field. 2. **The Armature**: The magnetic field pulls a hinged lever (armature) toward the core. 3. **The Contacts**: The movement of the armature forces the "Common" (COM) contact to move from the "Normally Closed" (NC) position to the "Normally Open" (NO) position. 4. **The Spring**: Once power is removed from the coil, a mechanical spring returns the contacts to their original state. ### Common Applications * **Industrial Controls**: PLC output modules and motor control. * **Home Appliances**: Power switching for HVAC systems or washing machines. * **Power Supplies**: Inrush current protection and power sequencing. * **Automotive Electronics**: Accessory power switching. ---
