The **M2AS1-5434-R** is a specific part number belonging to the **M2AS series** of miniature, high-frequency signal relays, typically manufactured by companies like **CIT Relay & Switch**. These components are designed for low-level signal switching, often used in telecommunications, security systems, and medical equipment. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Contact Form** | DPDT (2 Form C) | | **Coil Voltage** | 5V DC (Nominal) | | **Contact Rating** | 2A @ 30VDC / 0.5A @ 125VAC | | **Max Switching Power** | 60W / 62.5VA | | **Coil Power Consumption** | ~140mW (Sensitive type) | | **Dielectric Strength** | 1000Vrms (between coil and contacts) | | **Mounting Type** | Through-hole (PCB Mount) | --- ### 2. Breakdown of the Part Number While nomenclature can vary slightly by manufacturer, the **M2AS1-5434-R** usually breaks down as follows: * **M2A**: Series designation (Subminiature Signal Relay). * **S**: Sensitivity (usually denotes a high-sensitivity coil, approx. 150mW). * **1**: Number of poles/Contact arrangement (often 2 Form C). * **5**: Nominal Coil Voltage (5 Volts). * **434**: Specific internal design revision or lead plating code. * **-R**: RoHS Compliance (Lead-free). --- ### 3. Electronic Features * **Bifurcated Contacts:** The internal contacts are often split (bifurcated) to ensure high reliability when switching very low currents (gold-clad silver contacts). * **Fully Sealed:** These relays are typically "Washable" or "Sealed," meaning they can withstand automatic wave soldering and cleaning processes without contamination entering the internal mechanics. * **Small Footprint:** Designed to occupy minimal PCB real estate, making them ideal for high-density electronic assemblies. --- ### 4. Common Applications 1. **Telecommunications:** PABX systems, modems, and networking hardware. 2. **Instrumentation:** Test equipment and measurement devices where signal integrity is critical. 3. **Security:** Control panels and sensor switching. 4. **Audio/Video:** Signal routing in professional audio mixers or switching matrices.
