## 2. Key Electronic Components
The internal circuitry of the IRS060 series generally consists of the following electronic stages:
### A. Photo-Electronic Scanning System
* **LED Emitter:** A high-reliability infrared LED serves as the light source.
* **Code Disc:** A glass or plastic disc with etched radial lines that interrupt the light beam.
* **Photodiode Array:** Receives the light pulses and converts them into low-level electrical currents.
### B. Signal Processing (ASIC)
* **Comparator Circuit:** Converts the analog sinusoidal signals from the photodiodes into digital square waves (TTL/HTL).
* **Interpolation Logic:** High-resolution versions use internal interpolation to multiply the base pulses for higher accuracy.
### C. Output Driver Stage
* **Line Driver:** Most industrial versions use a **75176** or similar RS422 differential driver chip. This allows for long cable runs by transmitting complementary signals (A, /A, B, /B, Z, /Z) to cancel out electromagnetic interference (EMI).

| Pin/Wire Color | Signal | Function |
| :--- | :--- | :--- |
| Red | Vcc | Power Supply (+) |
| Black | GND | Ground (0V) |
| Green | A | Channel A (Position) |
| Yellow | /A | Inverted Channel A |
| White | B | Channel B (Direction) |
| Blue | /B | Inverted Channel B |
| Orange | Z | Index Pulse (Reference) |
