Yl-105 Datasheet Fixed May 2026

typically refers to a specific mechanical seal model used in industrial pumping applications. While "YL-105" can occasionally appear in other catalogs (like UV lacquers or capacitors), the primary datasheet information describes it as a reliable component for chemical and sewage pumps.

What is the YL-105?

The YL-105 is an IR tracking and obstacle avoidance sensor. It combines an infrared emitter and a phototransistor receiver on a small PCB with onboard comparator circuitry. typically refers to a specific mechanical seal model

6. Important Technical Notes

  1. Matching Transmitter: You must use a transmitter that operates at 433MHz. Common pairs are the FS1000A or XY-FS modules.
  2. Antenna Orientation: The antenna should be kept straight and away from metal objects or circuit boards to ensure maximum range.
  3. Decoder Chip: If you look closely at the PCB, you might see a black "blob" (COB - Chip on Board) or a specific IC. These modules often use chips like the RX480E or similar superheterodyne receiver ICs.
  4. Data Inversion: Most of these modules output "Active High" data. If you are getting garbage data, check if your library expects inverted signals (rare, but possible with specific transmitter combinations).
  5. Range: With a proper 17cm antenna on both the transmitter and the YL-105, you can achieve 50m-100m range indoors and significantly more outdoors (Line of Sight).
