The **M2PA-1B-R2/CE** is a high-performance, plug-in type industrial electromagnetic power relay manufactured by **Omron**. It is primarily used in control panels, automation systems, and high-current switching applications. --- ### ## Technical Specifications Below is a detailed breakdown of the electronic and mechanical characteristics of the M2PA series: | Parameter | Specification | | :--- | :--- | | **Contact Form** | SPDT (1 Form C) | | **Contact Material** | Silver alloy (Ag-alloy) | | **Rated Load (Resistive)** | 10 A at 250 VAC / 10 A at 30 VDC | | **Max. Switching Voltage** | 250 VAC / 125 VDC | | **Max. Switching Current** | 10 A | | **Coil Voltage (Standard)** | Typically 24VDC or 100/110VAC (Model dependent) | | **Power Consumption** | Approx. 0.9 W (DC) / 1.2 VA (AC) | | **Dielectric Strength** | 2,000 VAC (50/60 Hz for 1 min) | | **Mechanical Life** | 10,000,000 operations min. | | **Electrical Life** | 100,000 operations min. (at rated load) | --- ### ### Key Electronic Components & Design 1. **Electromagnetic Coil:** The "heart" of the relay. When energized, it creates a magnetic field that pulls the armature to switch the contacts. The R2 designation often refers to specific coil sensitivities or internal diode protections for back-EMF suppression. 2. **Contact System:** It utilizes a "Single Pole Double Throw" (SPDT) configuration. This allows the device to toggle a circuit between a "Normally Closed" (NC) and "Normally Open" (NO) state. 3. **Built-in Indicator:** The "R" in the suffix usually denotes a **Mechanical Indicator** or an **LED Indicator**, allowing technicians to visually verify if the relay is energized without using a multimeter. 4. **CE Compliance:** The "/CE" suffix signifies that the part meets European safety, health, and environmental protection requirements, making it suitable for international industrial machinery. --- ### ### Termination and Mounting The M2PA-1B-R2/CE is designed for **Plug-in Mounting**. It is typically paired with a DIN-rail socket (such as the Omron P2CF series). This allows for: * **Rapid Maintenance:** Faulty relays can be swapped without rewiring. * **Vibration Resistance:** The plug-in pins are designed to maintain high-pressure contact even in vibrating industrial environments. ---
