<p>Honeywell SS451A hall effect sensor is used in a variety of commercial, industrial and medical applications like medication bin monitor, printer head position sensing, robotic control, speed and RPM sensing in fitness equipment and others. Hall effect sensors are triggered by a magnetic field and operate as analog transducers to return a voltage directly. These sensors have varying output voltages in correspondence with the magnetic fields.</p><p>This RoHS-complaint SS451A device has built-in reverse polarity protection, which safeguards it from potential damage during installation. It features a thermally balanced integrated circuit, which allows stable operations across temperatures ranging from -40 °C to 150 °C. Featuring a low voltage 3V capability, this Honeywell Sensor consumes less power.</p>
