Expansion/Recovery: For a "3/4" tubing, the supplied internal diameter (ID) is 0.75 inches. After full recovery (shrinking), the ID will reduce based on the ratio (e.g., to 0.375" for 2:1 or 0.25" for 3:1).
Wall Thickness: The recovered wall thickness is vital for mechanical protection and insulation.
Chemical Resistance: These tubings are typically resistant to common oils, solvents, and fuels, making them suitable for automotive and industrial environments.
Environmental Compliance: They are generally RoHS compliant and meet various MIL-SPEC standards (like AMS-DTL-23053). 4. Application Best Practices
Heat Application: Use a heat gun rather than an open flame to ensure even shrinkage and avoid charring the yellow pigment. Sizing
: Always choose a diameter where the recovered (shrunk) ID is smaller than the diameter of the substrate you are covering to ensure a snug fit. Adhesive Seal: If using the FIT-300 (F300)
variant, the internal adhesive melts during heating to provide a moisture-proof seal.

I searched for a specific "YL-105" datasheet, but it is not a standard industry component code (like for a major IC, transistor, or sensor). This code is most likely used in one of two contexts:
Here is how to find a helpful paper/datasheet for the YL-105, depending on what the component actually is.
The LM393 does not have built-in hysteresis, but many YL-105 modules add a small positive feedback resistor. Check your board; if not present, you may experience output jitter near the threshold. The datasheet often omits this, so add hysteresis in software (debouncing) or external resistors if needed.
| Feature | YL-105 (Analog + Digital) | KY-003 (Magnetic Switch) | US1881 (Latching) | |---------|----------------------------|---------------------------|-------------------| | Output Type | Digital + Analog | Digital only | Digital (latching) | | Sensitivity Adjustment | Yes (potentiometer) | No | No | | Detectable Field Polarity | South pole only | South pole only | Both poles (latches) | | Best for | Adjustable proximity, RPM | Simple ON/OFF | Rotary encoders, door locks |
The YL-105 wins for flexibility due to its analog output and adjustable trigger point.
The YL-105 is not a bare Hall effect IC; it is a complete, ready-to-use Hall effect magnetic sensor module. It typically features a 49E (or equivalent) linear Hall sensor, a comparator circuit (often an LM393), a potentiometer for adjustable sensitivity, and onboard power regulation. The module outputs a clean digital signal (HIGH/LOW) based on the presence of a magnetic field, making it directly compatible with 3.3V and 5V microcontrollers like Arduino, Raspberry Pi, and ESP32.
The "YL" prefix indicates the manufacturer or PCB designer family (often associated with generic Chinese sensor modules), but the underlying sensor follows the standard 49E Hall effect sensor specifications.
