The **M22-WRLK-R** is a specific part number within the **Eaton (Moeller) RMQ-Titan** series of industrial control circuit devices. It is a high-quality, illuminated selector switch head designed for panel mounting. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The M22-WRLK-R is an **illuminated selector switch** actuator. It is important to note that this part number typically refers to the **actuator head only**. To form a functional electronic switch, it must be paired with a contact block and an LED element. | Feature | Specification | | :--- | :--- | | **Series** | M22 (RMQ-Titan) | | **Actuator Type** | Selector Switch (Thumb-grip) | | **Function** | Maintained (Stay-put) | | **Positions** | 2-position (e.g., 0 - 1) | | **Illumination** | Yes (Red) | | **IP Rating** | IP66 (Dust-tight, protected against heavy seas) | | **Mounting Diameter** | 22.5 mm | --- ### 2. Electronic Component Breakdown To understand the "electronic" side of this device, you must look at how it interacts with its modular accessories: #### A. Illumination (LED Element) * **Light Source:** This unit uses a red lens. For it to light up, an **M22-LED-R** (Red LED) block must be clipped to the back. * **Voltage Options:** LED blocks are available in various ranges: * 12 - 30 V AC/DC * 85 - 264 V AC * **Power Consumption:** Typically very low (~5-15 mA). #### B. Contact Blocks (The Switching Logic) The actuator physically moves a plunger that activates **M22-K10** (Normally Open) or **M22-K01** (Normally Closed) contact blocks. * **Rated Operational Voltage (Ue):** Up to 500V AC. * **Rated Operational Current (Ie):** 6A at 230V (AC-15). * **Compatibility:** Can hold up to two levels of contact blocks (typically 4 to 6 contacts total depending on the mounting adapter). --- ### 3. Physical & Environmental Data | Property | Details | | :--- | :--- | | **Switching Angle** | 60° | | **Color** | Red (Lens) / Titanium (Bezel) | | **Operating Temperature** | -25°C to +70°C | | **Mechanical Lifespan** | > 100,000 Operations | --- ### 4. Required Assembly Parts To make the M22-WRLK-R functional in a circuit, you generally need the following items: 1. **M22-WRLK-R**: The selector head (this part). 2. **M22-A**: The mounting adapter (clips the head to the contacts). 3. **M22-LED-R**: The red light engine. 4. **M22-K10/K01**: The electrical contact blocks. ---
