The **M2UDS-30-R2/N** is a specific part number typically associated with **M2U Series Magnetic Proximity Sensors** or safety switches, often produced by manufacturers like **IDEC** or related industrial automation brands. These devices are primarily used for non-contact door monitoring and position sensing in industrial safety systems. --- ### 1. Technical Specifications Below are the general electronic and mechanical specifications for this series: | Parameter | Specification | | :--- | :--- | | **Type** | Magnetic Safety Reed Switch | | **Contact Configuration** | 2NC (Normally Closed) / 1NO (Normally Open) - *Model dependent* | | **Sensing Distance** | ~5mm to 12mm (Safety ON), ~15mm to 30mm (Safety OFF) | | **Voltage Rating** | 24V DC (Standard) | | **Current Rating** | ~100mA to 200mA | | **Housing Material** | Robust Plastic (PBT or similar) | | **IP Rating** | IP67 (Water and dust resistant) | --- ### 2. Key Features * **Non-Contact Operation:** Uses magnetic fields to detect the presence of the actuator, eliminating mechanical wear and tear. * **Redundancy:** Usually features dual-channel outputs to comply with safety standards (SIL/PL ratings). * **Compact Design:** The "30" in the part number often refers to the form factor or specific mounting dimensions (30mm spacing or size). * **Environmental Resistance:** Designed to operate in harsh environments where oil, water, or dust may be present. --- ### 3. Wiring and Application These parts are typically wired to a **Safety Relay** or a **Safety Controller**. Because they are passive magnetic switches, they do not require a separate power supply for the sensor itself but act as a bridge for the safety circuit. #### Typical Wiring Logic: ```mermaid [Safety Controller] <------> [M2UDS Switch] <------> [Actuator/Magnet] ``` 1. **Closed State:** When the magnet (actuator) is near the sensor, the internal reed switches are held in their "safe" position, allowing the machine to run. 2. **Open State:** If the door is opened and the magnet moves away, the circuit breaks, signaling the controller to initiate an Emergency Stop. --- ### 4. Part Number Breakdown (Generic) * **M2U:** Series identifier (Magnetic Safety Unit). * **DS:** Door Switch / Dual Sensor configuration. * **30:** Size/Form factor or Sensing range designation. * **R2:** Likely indicates a Right-hand cable exit or a specific 2-meter cable length. * **N:** Often indicates the contact polarity or a specific "North" magnetic orientation requirement.
