HONEYWELL SS445P Hall Effect Rotary Position Sensor, Unipolar, 2.7 to 7V, TO-92-3

SS445P is an unipolar hall-effect digital position sensor with built-in pull-up resistor. It is a small, versatile digital hall effect device that is operated by the magnetic field from a permanent magnet or an electromagnet, designed to respond to a single south pole. This unipolar sensor is designed to meet the requirements of a wide range of potential applications. The internal pull-up resistor often eliminates the need for external components, further helping to reduce the system cost. This economical unipolar sensor is well suited for simple, high-volume, cost-sensitive position and motion sensing applications. The 2.7VDC to 7 VDC supply voltage range allows this device to be used in low voltage applications. The SS345PT�s very small size requires less PCB (printed circuit board) space, allowing it to be used in smaller assemblies. Applications include commercial, industrial and medical.
