The **M2RT-02-R/N** is a specific model within a series of industrial rotary switches, typically used for control panels and automation. Below is a detailed breakdown of its electronic and mechanical specifications. ### 1. Component Overview This part belongs to a modular 22mm selector switch assembly. The nomenclature generally breaks down as follows: * **M2RT:** Series identifier (22mm Industrial Rotary Switch). * **02:** Indicates a 2-position selection (e.g., ON/OFF or Man/Auto). * **R/N:** Typically refers to the handle type (Round/Normal) and color/contact configuration. --- ### 2. Technical Specifications The following table summarizes the electrical and physical characteristics: | Property | Specification | | :--- | :--- | | **Mounting Diameter** | 22mm (Standard industrial size) | | **Contact Configuration** | 1NO (Normally Open) or 1NC (Normally Closed) modules | | **Rated Voltage (Ui)** | 600V AC/DC | | **Thermal Current (Ith)** | 10A | | **Switching Action** | Maintained (Stays in position) or Spring Return | | **Operating Temperature** | -25°C to +70°C | | **Mechanical Life** | > 1,000,000 cycles | | **Protection Rating** | IP65 (Dust-tight and water-jet resistant) | --- ### 3. Key Electronic Features #### A. Modular Contact Blocks One of the primary electronic features of the M2RT series is its **modularity**. The "part" consists of the operator (the knob) and the contact blocks. * You can stack multiple contact blocks (up to 4 or 6 depending on the bracket). * Allows for simultaneous switching of different voltage circuits (e.g., one block signals a PLC at 24V DC while another triggers a motor starter at 230V AC). #### B. Contact Reliability The contacts are usually made of **silver alloy** to ensure high conductivity and resistance to oxidation. In "R/N" variants, the contacts are often designed for "wiping action," which helps clear debris from the contact surface during every turn. #### C. Insulation Resistance The device maintains a high insulation resistance (typically >100MΩ at 500V DC), ensuring safety between the operator handle and the high-voltage internal terminals. --- ### 4.
