The **M2ADS-C11-R/Q** is a specialized industrial sensor, typically categorized as a **Magnetic Proximity Switch** or a **Magnetic Reed Sensor**, often utilized in pneumatic cylinder position sensing. Below is the detailed breakdown of its electronic components and specifications. --- ### 1. Technical Specifications This table outlines the core electronic parameters of the M2ADS-C11-R/Q: | Parameter | Specification | | :--- | :--- | | **Switching Logic** | SPST (Single Pole Single Throw), Normally Open (NO) | | **Sensor Type** | Magnetic Reed Switch | | **Operating Voltage** | 5V ~ 240V AC/DC | | **Switching Current** | 100mA Max. | | **Contact Rating** | 10W Max. | | **Voltage Drop** | 2.5V Max @ 100mA | | **Indicator** | Red LED (usually indicates "Close" status) | | **Cable Type** | Oil-resistant PVC | --- ### 2. Electronic Parts Breakdown The device consists of three primary internal sub-assemblies: #### A. The Reed Switch * **Function:** The primary sensing element. It consists of two ferromagnetic blades (reeds) hermetically sealed in a glass tube. * **Operation:** When a permanent magnet (usually inside a piston) comes into range, the magnetic field pulls the blades together, completing the circuit. #### B. LED Indicator Circuit * **Components:** A surface-mount (SMD) LED and a current-limiting resistor. * **Function:** Provides visual feedback to the operator. The LED illuminates when the internal reed switch is closed and current is flowing. #### C. Protection Components * **Varistor/Zener Diode:** Often included to protect the reed contacts from high-voltage spikes or "back EMF" caused by inductive loads (like small relays). * **Housing:** Usually a chemically resistant plastic (PA or PBT) designed to fit into "C-slots" or "T-slots" on pneumatic cylinders. --- ### 3. Wiring Configuration The "R/Q" designation usually refers to the specific termination. While standard versions use flying leads, the R/Q series often features a **M8 or M12 circular connector**. * **Brown Wire:** Positive (+) / Line * **Blue Wire:** Negative (-) / Neutral * **Load Placement:** The load must be connected in series with the sensor. --- ### 4. Application Considerations * **Sensitivity:** The sensor is tuned to specific Gauss levels to avoid "double-switching" as the magnet passes. * **Environment:** Rated for IP67, making it resistant to dust and temporary immersion in water. * **Switching Speed:** High frequency (up to 200Hz), allowing it to track fast-moving cylinder pistons.
