Hall Effect Sensor SS44E TO-92 Hall Element Sensor Motor 3 Pins for Arduino
KSH 60.00
Out of Stock
The SS44E Hall Effect Sensor is a highsensitivity, TO92 packaged magnetic switch designed for precise magnetic field detection. This reliable sensor features an open-collector output that pulls low when a magnetic field (south pole) is detected, making it an essential component for position sensing, speed measurement, and proximity detection applications.
