Yl105 Datasheet Repack May 2026
(specifically the FIT-221 YL105 series) is a general-purpose, yellow-colored heat shrink tubing manufactured by Alpha Wire
Q5: Where can I download the official YL105 datasheet PDF?
A: Since YL105 is a generic module name, no single "official" PDF exists. Use this guide along with the datasheet of the actual Hall IC on your module (e.g., AH3144, SS441A, or OH137). yl105 datasheet
Magnetic Characteristics
| Parameter | Value | |-----------|-------| | Operate Point (Bop) | 10–30 mT (South pole facing marked side) | | Release Point (Brp) | 2–15 mT | | Hysteresis | 5–12 mT | Non-contact magnetic sensing – No moving parts, high
Inspect External RC Components: If a timer isn't lasting the correct duration, the external capacitor connected to the timing pins has likely drifted in value or leaked. Wiring example with Arduino:
5. Key Features from the YL105 Datasheet
- Non-contact magnetic sensing – No moving parts, high reliability.
- Digital output – Direct interface with microcontrollers (Arduino, STM32, ESP32, Raspberry Pi).
- Adjustable sensitivity – Onboard potentiometer for setting trigger distance.
- Power indicator – Shows module is powered.
- Response frequency – Up to 100 kHz (suitable for RPM measurement on small motors).
- Reverse polarity protection – On better modules.
