The **M2ADS-113-R2/Q** is a specific electronic component typically categorized as a **Magnetic Speed/Position Sensor** or an **Active Speed Sensor**, commonly utilized in industrial automation and automotive applications. --- ### 1. Component Overview This part is designed to detect the movement, speed, or position of a ferrous target (like a gear tooth or a magnetized ring) without physical contact. | Feature | Description | | :--- | :--- | | **Component Type** | Hall-Effect or Magnetoresistive (MR) Sensor | | **Housing Material** | Usually Stainless Steel or High-Grade Polymer | | **Output Signal** | Digital Square Wave (Push-Pull or Open Collector) | | **Operating Voltage** | Typically 5V to 24V DC | | **Connection Type** | M12 Connector or Flying Leads (depending on sub-variant) | --- ### 2. Key Electronic Characteristics The "R2/Q" suffix often indicates specific electrical configurations or qualification standards. * **Sensing Principle:** It utilizes a solid-state sensing element that changes its electrical resistance or voltage in the presence of a magnetic field. * **Integrated Electronics:** The unit contains internal signal conditioning circuitry that converts raw analog signals into a clean digital pulse. * **Protection Circuitry:** * **Reverse Polarity Protection:** Prevents damage if the power leads are swapped. * **Short Circuit Protection:** Safeguards the sensor output against wiring errors. * **EMC Shielding:** Hardened against electromagnetic interference (EMI) common in industrial environments. --- ### 3. Pinout & Typical Wiring While you should always consult the specific datasheet for your batch, standard M12 industrial sensors follow this general logic: | Pin Number | Wire Color | Function | | :--- | :--- | :--- | | **1** | Brown | +VCC (Power Supply) | | **2** | White | Complementary Output (Not always used) | | **3** | Blue | GND (0V / Common) | | **4** | Black | Signal Output (Digital Pulse) | --- ### 4. Technical Specifications Table | Specification | Typical Value | | :--- | :--- | | **Frequency Range** | 0 Hz to 15 or 20 kHz | | **Operating Temperature** | -40°C to +125°C | | **Air Gap** | 0.5mm to 2.5mm (Target dependent) | | **Degree of Protection** | IP67 or IP68 (Dust/Waterproof) | --- ### 5. Common Applications * **Engine Timing:** Monitoring crankshaft or camshaft position. * **Traction Control:** Measuring wheel speed for ABS systems. * **Conveyor Systems:** Counting pulses to determine belt speed or distance traveled. * **Flow Meters:** Detecting the rotation of internal turbines.
