DESCRIPTION
The SS400 Series sensor ICs are small, versatile, digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles or to a South pole only. Bipolar, latching and unipolar magnetics are available.
Band gap regulation provides stable operation over 3.8 Vdc to 30 Vdc supply voltage range. These sensors are capable of continuous 20 mA sinking output and may be cycled as high as 50 mA max. Its 3.8 V capability allows for use in many potential low voltage applications.
The digital, open collector sinking-type output is easily interfaced with a wide variety of electronic circuits.
To provide reliable products and consistent quality, the SS400 Series are tested at both 25 °C [75 °F] and 125 °C [257 °F]. All catalog listings in this series are qualified for operation up to 150 °C [302 °F].
For design flexibility, the lead and packaging options are: Straight leads, 14,99 mm [0.59 in] long, in bulk or ammopak tape-in-box packaging Straight leads, 18,7 mm [0.735 in] long, in bulk packaging Formed leads, 14,99 mm [0.59 in] long, in bulk or ammopak tape-in-box packaging
Please refer to SS400 Series Order Guide on page 7 for details.
