DESCRIPTION:
The SS400F and SS400G Series sensors are small, versatiledigital Hall-effect devices that are operated by the magneticfield from a permanent magnet or an electromagnet, and aredesigned to respond to alternating North and South poles or toa South pole only. Bipolar, latching and unipolar magnetics areavailable.
Band gap regulation provides stable operation over 3.8 Vdc to30 Vdc supply voltage range. These sensors are capable ofcontinuous 20 mA sinking output and may be cycled as high as50 mA max. Its 3.8 V capability allows for use in many potentiallow voltage applications.
FEATURES:
Temperature-compensated magnetics
Miniature plastic package
Low voltage: 3.8 V operation
POTENTIAL APPLICATIONS:
Transportation:
Speed and RPM (revolutions per minute) sensing
