Digital TTL (Low level when an obstacle is detected, High level when clear) Onboard Comparator: LM393 chip for stable signal processing Dimensions: 32mm × 14mm
This comprehensive guide serves as an expanded technical datasheet, explaining how the FC-51 works, its electrical specifications, pinout, adjustment procedures, and integration steps. Technical Specifications
The LM393 comparator has an open-collector output on some designs, requiring a pull-up resistor internally. In practice, this means the signal idles HIGH and pulls LOW upon detection.
By referencing this , you now have the complete technical picture: pinouts, voltage limits, range adjustment, code examples, and troubleshooting. Whether you’re building a line-following robot, a contactless switch, or a factory counter, the FC-51 offers a straightforward “detect or not detect” solution that integrates with almost any microcontroller.
