Distributor Inventory

The SS351AT, SS451A and SS551AT sensors are small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to a either a North pole or a South pole.

These omnipolar sensors are sensitive and flexible devices designed to meet a wide range of potential applications. The SS351AT, SS451A and SS551AT have a typical operating point of 85 G at 25 °C [77 °F]. Because they can be operated by a North pole or a South pole, they do not require the magnet polarity to be identified, thus making the installation easier and potentially reducing the system cost.

These sensors are available in three package styles. The SS351AT is available in the subminiature SOT-23 surface mount package: the SS451A is available in the leaded, flat TO-92-style package, and the SS551AT is supplied in the SOT-89B surface-mount package. The SS351AT’s small size requires less PC board space, allowing it to be used in smaller assemblies. Its 3 Vdc capability allows for use in low voltage applications, promoting energy efficiency.

The SS351AT is available on tape and reel (3000 units per reel): the SS451A is available in a bulk package (1000 units per bag), and the SS551AT is available on tape and reel (1000 units per reel).
