The SS400F and SS400G Series sensors 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.

• Temperature-compensated magnetics
• Miniature plastic package
• Low voltage: 3.8 V operation
• The digital collector sinking output voltage is easily interfaced with a wide variety of electronic circuits.
• The SS400F Series (catalog listings ending with F) are 100% factory tested at 25 °C [77 °F] and the SS400G Series (catalog listings ending with G) are 100% factory tested at 125 °C [302 °F]. Both series are qualified for operation up to 150 °C [302 °F].
