The **M2TT-NE-R2SLASHCE** is a specific part number belonging to the **M2TT series** of industrial control switches, manufactured by **IDEC**. This component is a sub-assembly, specifically a **Switch Unit (Contact Block)** used in heavy-duty push-button configurations. --- ### 1. Component Identification The part number breaks down into specific technical characteristics regarding its electrical and mechanical design: | Part Segment | Description | Technical Detail | | :--- | :--- | :--- | | **M2TT** | Series Name | Miniature/Industrial Control Unit Series | | **NE** | Contact Type | Normally Open (NO) / Normally Closed (NC) configurations | | **R2** | Mounting Style | Specific to the 22mm or 30mm mounting diameters (standard industrial) | | **CE** | Certification | Compliant with European Conformity (CE) safety standards | --- ### 2. Electrical Specifications This part acts as the "brain" of a push-button, converting mechanical movement into an electrical signal. * **Insulation Voltage (Ui):** Typically rated for 600V. * **Thermal Current (Ith):** Usually rated up to 10A to handle industrial motor starters. * **Contact Material:** Silver-alloy (AgNi or AgCu) for low contact resistance and high durability. * **Contact Configuration:** Often features a **DPDT** (Double Pole Double Throw) or **2NO/2NC** internal structure depending on the specific pinout. --- ### 3. Key Electronic Features #### A. Modular Design The "NE" designation usually refers to a snap-on contact block. This allows the electronic switching element to be separated from the mechanical actuator (the button or lever), making it easier to replace if the contacts wear out without replacing the entire housing. #### B. Self-Cleaning Action The internal contacts utilize a **wiping action**. Every time the switch is toggled, the metal surfaces rub against each other slightly, which removes oxidation and ensures a reliable electronic connection even in dusty environments. #### C. Terminal Type * **Screw Terminals:** Typically features "IP20" finger-safe screw terminals to prevent accidental shock. * **Wire Compatibility:** Supports stranded or solid wire ranging from 14 AWG to 22 AWG. --- ### 4. Application Environments Because of the **CE** rating and the rugged construction, these parts are found in: 1. **CNC Control Panels:** For cycle starts or emergency stops. 2. **PLCs Input Modules:** Sending 24V DC signals to industrial controllers. 3. **Power Distribution:** Manual override switches for circuit breakers. --- ### 5.
