: Protects internal components against common industrial fluids, oils, and solvents.
Below is a detailed datasheet table synthesizing the electrical and physical properties from the manufacturer and leading distributors for common FIT®-221 YL105 models.
The PCB layout (visible in the datasheet’s mechanical drawing) has long, unshielded traces. This makes the module susceptible to . The datasheet provides zero guidance on filtering or external capacitors.
A: Official datasheets are available from: yl105 datasheet
The code "YL" is an abbreviation for "Yellow", a standard color for wire and cable management used in low-voltage wiring, industrial control panels, and safety applications. The specific numeric code "105" refers to the packaging configuration, typically indicating the tubing is supplied in a and is often sold in a bulk or spool package.
The 2×4 female socket delivers clean 3.3V power to the transceiver along with uninhibited logic pathways for the SPI data signals. Key Architectural Features Onboard Power Regulation via AMS1117-3.3 I Can't get nRF2401 to work - Programming - Arduino Forum
: Actuates RX or TX modes. Pass-through to the radio. This makes the module susceptible to
“The museum’s new LED emergency lights,” Aris whispered. “They’re deep red. The datasheet warns about ‘false triggering in high-intensity non-IR sources.’”

Unlike industrial Hall sensors (e.g., from Allegro or Melexis), the YL-105 datasheet provides . In practice, the analog output will drift significantly with temperature (±10% or more across 0-50°C). For indoor hobby projects, fine. For outdoor or industrial use? Avoid. The specific numeric code "105" refers to the
As explained, "YL" = Yellow, "105" = Packaging: 4-foot piece.
