The **M2SES-2BA-R** is a specific electronic component, typically categorized as a **Sealed M2 Style Miniature Toggle Switch** or a specific industrial control component depending on the manufacturer (often associated with brands like Mors Smitt or similar industrial relay/switch suppliers). Below is a breakdown of the electronic specifications and characteristics typically associated with this part series. --- ### 1. General Specifications This component is designed for high-reliability environments, often used in railway, industrial automation, or heavy machinery. | Feature | Specification | | :--- | :--- | | **Component Type** | Miniature Toggle Switch / Micro-switch | | **Contact Configuration** | 2BA (Double Pole, often signifies specific contact arrangement) | | **Terminal Type** | Solder or PC terminals (depending on suffix) | | **Sealing** | Environmentally sealed (Water/Dust resistant) | | **Actuator Style** | Standard Lever / Toggle | --- ### 2. Electrical Characteristics These parts are engineered to handle specific voltage and current loads while maintaining low contact resistance. * **Contact Rating:** Generally rated for **5A at 125VAC** or **2A at 250VAC**. * **Insulation Resistance:** Minimum of 1,000 MΩ at 500VDC. * **Dielectric Strength:** Usually 1,000V RMS at sea level. * **Mechanical Life:** Designed for over 40,000 to 100,000 make-and-break cycles. --- ### 3. Key Electronic Materials The internal construction of the M2SES series focuses on durability: 1. **Contacts:** Often Silver (Ag) or Gold-plated over Silver to prevent oxidation in low-power circuits. 2. **Case & Bushing:** Glass-filled nylon or Diallyl Phthalate (DAP) for high heat resistance and electrical insulation. 3. **Seal:** An internal O-ring on the actuator and an epoxy seal on the terminals to prevent flux or contaminants from entering. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by brand, the code usually breaks down as follows: * **M2:** Refers to the series/size (Miniature). * **S:** Indicates a Sealed construction. * **E:** Often refers to the Epoxy terminal seal. * **2BA:** Specifies the switching function (e.g., DPDT On-On or On-Off-On) and the mounting hardware. * **R:** Usually denotes **RoHS Compliance** or a specific Right-Angle orientation. --- ### 5. Application Use-Cases * **Control Panels:** Used in ruggedized handheld controllers. * **Railway Systems:** Due to its high vibration resistance. * **Medical Equipment:** Where sealing against fluids is necessary. * **Telecommunications:** For signal switching in outdoor enclosures.
