Description:The 44E115 is an integrated Hall effect nonlatching sensor. Holding a magnet near the sensor will cause its output pin to toggle. This makes for a robust magnet presence sensor. A reed sensor also works nicely but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller but can handle less current than a reed switch. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator provides temperature-compensated supply voltage for internal circuits and allows a wide operating supply range. If a magnetic flux density is larger than threshold Bop, DO is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high).Features:3.5V to 24V DC operation voltageLow current consumptionTemperature compensationWide operating voltage rangeOpen-Collector pre-driver50mA maximum sinking output currentReverse polarity protectionLead Free Package: TO-92Applications:Proximity Switching.Positioning.Speed Detection.Current sensing applications.DIY projects.Robotics projects.Arduino projects.Raspberry-Pi projects.Electrical/Electronic projects.Package:1x 44E115 Hall Effect Sensor
