Product Description:

SS551AT SS351AT SS451A Full-Range Hall Effect Digital Position Sensor Ics

Features:

SS551AT Hall Effect digital position sensor IC, full polarity, low sensitivity, SOT-89B, 1000 units/pocket tape and reel.

The SS551AT series of low-cost bipolar Hall effect sensor ics adopt surface mount packaging and feature thermal balance integrated circuits throughout the entire temperature range. Bipolar magnetic responses alternate between the North Pole and the South Pole.

The built-in voltage stabilizer can provide very stable operation within the power supply voltage range of 4.5Vdc to 24Vdc. The internal circuit can prevent sensor damage and avoid unexpected reversal of the power supply voltage polarity. The SS50AT series of low-cost bipolar Hall effect sensors are small, multi-functional digital Hall effect devices operated by the magnetic fields of permanent magnets or electromagnets. The output voltage of the collector open drain can be easily connected to various electronic circuits.

Note: Integrated circuits offer excellent temperature stability and accuracy in robust designs. The operating temperature range of these digital Hall sensors is -40°C to 125°C [-40°F to 257°F], making them suitable for commercial, consumer and industrial environments.
