The **M2AS1-5311-R/N** is a specialized electronic component, typically categorized as a **Magnetic Proximity Sensor** or a **Reed Switch Assembly**, often used in industrial automation, security systems, and position sensing. --- ### 1. Technical Specifications The part number typically follows a specific nomenclature for magnetic sensors. Below are the general electronic characteristics associated with this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Contact Form** | Form A (Normally Open) | | **Switching Voltage** | Max 200V DC / 140V AC | | **Switching Current** | Max 0.5A | | **Carry Current** | Max 1.0A | | **Contact Rating** | 10VA (Watts) | | **Operating Distance** | 5mm to 15mm (depending on magnet strength) | | **Housing Material** | ABS Plastic or Stainless Steel (Environmentally sealed) | --- ### 2. Internal Electronic Parts The device consists of three primary internal components: 1. **Reed Switch:** Two ferromagnetic blades hermetically sealed in a glass envelope. When a magnetic field is introduced, the blades pull together to close the circuit. 2. **Protective Resistor/Diode (Optional):** Some versions include an internal series resistor for current limiting or a flyback diode to protect against inductive spikes. 3. **Encapsulation:** The internal reed switch is potted with epoxy resin to protect it from vibration, moisture, and mechanical shock. --- ### 3. Connection Diagram The device is usually a two-wire passive component. Below is a simple representation of its integration: ```mermaid graph LR A[Power Source] --> B(M2AS1 Sensor) B --> C[Load/PLC Input] C --> D[Ground/Common] ``` --- ### 4. Key Features & Applications * **No Power Required:** As a passive magnetic switch, it does not require a standby power supply. * **Non-Contact Sensing:** Operates through non-ferrous materials (plastic, wood, aluminum). * **Durability:** The "R/N" designation often refers to RoHS compliance and specific mounting orientations (Right-angle or Narrow). **Common Uses:** * Door and window position monitoring in security. * End-of-travel limit switching in pneumatic cylinders. * Liquid level sensing (when paired with a magnetic float).
