The **M2ADS-Z22-R** is a specific model within the series of Industrial Emergency Stop (E-Stop) switches, typically manufactured by brands like **IDEC** or similar industrial control component providers. It is designed for panel mounting in automation and machinery safety circuits. --- ### 1. Technical Specifications Below are the primary electronic and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Actuator Type** | 40mm Mushroom Head (Non-Illuminated) | | **Reset Method** | Push-Lock, Turn-Reset | | **Contact Configuration** | 2NC (2 Normally Closed safety contacts) | | **Mounting Hole Size** | 22mm Diameter | | **Contact Rating** | 600V AC/DC (Standard Industrial Grade) | | **IP Rating** | IP65 / IP66 (Dust-tight and water-resistant) | | **Terminal Type** | Screw Terminals | --- ### 2. Key Electronic Components The "Electronic" nature of this part refers to its role as a **passive electromechanical switch**. It does not contain microprocessors but functions as a critical safety interlock. #### A. Contact Blocks (The 22-R suffix) * **2NC Configuration:** This part features two independent "Normally Closed" circuits. In a safety system, these are wired in series with a safety relay. * **Positive Opening Operation:** The contacts are designed to be forced open by the physical movement of the button, ensuring the circuit breaks even if the contacts have lightly welded due to an overcurrent. #### B. The Latching Mechanism * **Push-Lock:** When pressed, the internal mechanical latch holds the contacts in the "Open" (OFF) position. * **Turn-Reset:** The operator must physically rotate the mushroom head to release the latch, ensuring that machinery cannot restart automatically without human intervention. #### C. Safety Standards Compliance As an electronic safety component, it is designed to meet: * **ISO 13850:** Safety of machinery (Emergency stop functions). * **IEC 60947-5-5:** Electrical standards for E-stop devices with mechanical latching. --- ### 3. Typical Wiring Example In a standard safety circuit, the M2ADS-Z22-R is wired to a Safety Monitoring Relay: ```mermaid graph LR A[24V DC Source] --> B[E-Stop NC 1] B --> C[E-Stop NC 2] C --> D[Safety Relay Input] D --> E[Control Circuit Power] ``` ---
