The **M2AVS-4112-R** is a specific model of an **Incremental Rotary Encoder**, typically manufactured by companies like NEMICON or similar industrial sensor providers. It is designed to convert mechanical rotational displacement into electrical signals. --- ## 1. Technical Specifications Overview Below is a breakdown of the typical electronic and physical parameters for this series: | Parameter | Specification | |:---|:---| | **Type** | Incremental Rotary Encoder | | **Output Phase** | A, B, and Z (Index) phases | | **Resolution** | 1024 Pulses Per Revolution (PPR) | | **Supply Voltage** | 5V DC to 12V DC (typical range) | | **Output Type** | Voltage Output / Open Collector | | **Shaft Diameter** | 6mm (Standard "Solid Shaft") | | **Outer Diameter** | 40mm | --- ## 2. Key Electronic Components & Functions ### A. The Optical Disc At the heart of the M2AVS-4112-R is a coded glass or plastic disc. As the shaft rotates, the disc interrupts an internal light beam, creating a pulse train. ### B. Output Signals (A, B, Z) * **Phase A & B:** These two square wave signals are offset by 90 electrical degrees (quadrature). This allows the controller to determine both the **speed** and the **direction** of rotation. * **Phase Z:** Also known as the "Index" or "Home" pulse. It produces one pulse per full 360-degree revolution, used for reference positioning. ### C. Output Circuitry The "R" suffix often denotes specific wiring or output characteristics. Most M2AVS models use a **Voltage Output** configuration: * It utilizes an internal pull-up resistor. * It is compatible with most PLC high-speed counter cards and microcontrollers (like Arduino or ESP32). --- ## 3. Wiring Configuration The device typically uses a color-coded cable. While you should always verify with the specific datasheet provided with the unit, standard wiring for this series is: | Wire Color | Function | |:---|:---| | **Red** | Vcc (Power Supply +) | | **Black** | 0V (Ground) | | **White** | Signal Phase A | | **Green** | Signal Phase B | | **Yellow** | Signal Phase Z | | **Shield** | Frame Ground / Shielding | --- ## 4. Application Use Cases 1. **Motor Feedback:** Measuring the RPM of a DC or AC motor. 2. **Positioning:** Calculating the distance traveled by a conveyor belt or linear actuator. 3. **Human-Machine Interface:** Used as a high-precision digital dial for industrial machinery settings.
