Based on the part number provided, this appears to be a specific configuration of a **Pressure Switch/Sensor** or a **Pushbutton Switch** (often associated with industrial automation brands like Altech or similar manufacturers). Below is a detailed breakdown of the electronic and mechanical specifications typical for this series. --- ### 1. General Specifications The **M2AS1-A221-R2/Q** is designed for industrial control panels. It typically falls under the category of a 22mm pilot device. | Feature | Specification | | :--- | :--- | | **Mounting Diameter** | 22.5 mm | | **Operator Type** | Momentary or Maintained (Model specific) | | **Contact Configuration** | 1NO + 1NC (Commonly) | | **Illumination** | LED / Non-illuminated (Model specific) | | **Protection Rating** | IP65 / NEMA 4X (Water/Dust resistant) | --- ### 2. Electronic Component Breakdown #### A. Contact Blocks These are the electronic switching elements attached to the back of the actuator. * **A221 Designation:** Usually refers to the contact arrangement. In many industrial schemas, this signifies a specific combination of **Normally Open (NO)** and **Normally Closed (NC)** circuits. * **Voltage/Current Rating:** Typically rated for 10A at 120V AC or 6A at 240V AC. #### B. Terminal Design * **Screw Terminals:** The "R2" or "Q" suffix often denotes the wiring method. * **Q-type:** Often refers to "Quick Connect" or "Faston" terminals (6.3mm or 4.8mm tabs). * **R-type:** Can denote a specific contact block material (e.g., silver-plated) or a specific wiring orientation (Rear-entry). #### C. Electrical Durability * **Mechanical Life:** ~1,000,000 cycles. * **Electrical Life:** ~500,000 cycles at full load. * **Insulation Resistance:** >100 MΩ at 500V DC. --- ### 3. Application Examples Industrial electronics use these parts for the following functions: 1. **Motor Control:** Acting as a "Start" or "Stop" signal for magnetic contactors. 2. **Logic Inputs:** Sending signals to a PLC (Programmable Logic Controller) digital input module. 3. **Safety Interlocks:** Breaking a circuit when a physical guard is moved. --- ### 4.
