SS551AT

SS551AT Omnipolar, Hall-effect digital position sensor IC, low sensitivity, SOT-89B, 1000 units/pocket tape and reel

The SS551AT Series Low-Cost Bipolar Hall-Effect sensors in a surface-mount package have a thermally balanced integrated circuit over full temperature range. The bipolar magnetics respond to alternating North and South poles.

A built-in regulator provides very stable operation over 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry prevents sensor damage in case the supply voltage polarity is accidentally reversed. The SS50AT Series Low-Cost Bipolar Hall-Effect sensors are small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic circuits.

NOTE: The integrated circuitry provides excellent temperature stability and accuracy in a robust design. These digital Hall sensors have an operating temperature range of -40 °C to 125 °C [-40 °F to 257 °F], appropriate for commercial, consumer, and industrial environments.
