Additional Details

The SS526DT Hall-effect latch operates by detecting the presence and polarity of a magnetic field. When a magnetic field of sufficient strength and the correct polarity is applied, the sensor's output switches to one state and latches. To switch the output to the opposite state, a magnetic field of the opposite polarity must be applied. This latching functionality makes the sensor suitable for applications requiring stable and reliable switching. The sensor is typically powered by a DC supply voltage. Its small size and robust design make it a popular choice for a variety of latching applications. A pull-up resistor is usually required for the output to interface correctly with a microcontroller or other logic.
