The **M2TS-7A-R/CE** is a specialized precision component typically associated with industrial automation and control systems, specifically within the category of **Limit Switches** or **Position Sensors**. Below is a detailed breakdown of its electronic and mechanical parts. --- ### 1. Technical Specifications This table summarizes the core electrical and mechanical parameters for the M2TS series: | Parameter | Specification | | :--- | :--- | | **Contact Type** | Snap-action (usually 1NO + 1NC) | | **Actuator Style** | Roller Lever (adjustable) | | **Current Rating** | 5A to 10A (Depending on AC/DC voltage) | | **Ingress Protection** | IP67 (Dust tight and immersion resistant) | | **Body Material** | Die-cast Aluminum or Zinc Alloy | | **Operating Temperature** | -20°C to +70°C | --- ### 2. Key Internal Electronic Parts #### A. Contact Block The "heart" of the switch. It consists of high-conductivity silver or gold-plated contacts. * **Common (C):** The input terminal. * **Normally Open (NO):** Closes the circuit when the lever is pressed. * **Normally Closed (NC):** Opens the circuit when the lever is pressed. #### B. Snap-Action Mechanism Unlike a slow-break switch, the snap-action mechanism uses a spring-loaded toggle. This ensures that the contacts move at a constant speed regardless of how slowly the external lever is moved, preventing **arcing** and electrical wear. #### C. Terminal Block Located inside the base of the unit, usually featuring screw terminals for secure wiring. The "CE" designation indicates compliance with European safety standards, often requiring protective grounding/earthing terminals. #### D. Sealing Gaskets Internal rubber seals (usually NBR or Silicone) protect the electronic contacts from oil, water, and coolants, maintaining the **IP67 rating**. --- ### 3. Actuator Mechanics (7A-R Designation) The "7A-R" suffix typically refers to the physical interface: * **7A:** Represents an **Adjustable Roller Lever**. This allows the operator to change the length of the arm to fit the machinery. * **R:** Often denotes a "Roller" made of hardened plastic or stainless steel to reduce friction against the triggering cam. --- ### 4. Wiring Diagram Representation The electrical circuit for this part is generally represented as follows: ```mermaid graph LR L1(Line/Input) --- COM[Common Terminal] COM -- Default -- NC[Normally Closed Output] COM -- Triggered -- NO[Normally Open Output] ``` ---
