The **M2SES-1A2-R2/CE** is a specialized industrial sensor, typically identified as an **Inductive Proximity Sensor** or part of a safety interlock system (often associated with brands like Macreer or similar industrial automation suppliers). Below is a breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This device is designed for non-contact detection of metallic objects or as a magnetic actuator for safety switches. | Feature | Specification Details | | :--- | :--- | | **Type** | Inductive Proximity / Magnetic Safety Switch | | **Output Configuration** | 1 NO (Normally Open) | | **Sensing Distance** | Typically 2mm to 5mm (depending on target) | | **Voltage Range** | 12V - 24V DC (Common for CE rated parts) | | **Mounting** | M12 Threaded (Shielded/Flush) | | **Connection** | Cable Lead or M12 Connector (R2 indicates revision/cable type) | --- ### 2. Key Electronic Components The internal circuitry of this part consists of several critical stages to ensure industrial reliability: * **Oscillator Circuit:** Generates a high-frequency electromagnetic field at the sensing face. * **Schmitt Trigger:** Processes the analog signal from the oscillator into a clean "High" or "Low" digital signal to prevent "chatter" or false triggering. * **Output Transistor:** Usually a PNP or NPN transistor (depending on the specific sub-wiring) that acts as the switch for the load. * **Protection Diodes:** Includes Reverse Polarity Protection and Surge/Transient suppression to protect against inductive spikes. --- ### 3. Standards and Compliance The suffix in the model number denotes adherence to specific regulatory requirements: 1. **CE Marking:** Indicates the part complies with European safety, health, and environmental protection requirements (EMC Directive). 2. **IP Rating:** Generally rated **IP67**, meaning it is dust-tight and protected against temporary immersion in water. 3. **R2 Revision:** Often signifies a specific cable length (e.g., 2 meters) or a specific material revision for the housing (e.g., Stainless Steel vs. Brass). --- ### 4.
