DESCRIPTION

The SS361CT and SS461C High Sensitivity Latching Hall-effect Sensor ICs are small, sensitive, and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles. The SS361CT is turned on by a North pole while the SS461C is turned on by a South pole.

These products offer reverse polarity protection and deliver enhanced sensitivity of only 50 G typical, at 25 °C [77 °F], 80 G max. at -40 °C to 85 °C [-40 °F to 185 °F], and 95 G over the full temperature range, allowing the use of smaller, potentially lower-cost magnets or wider air gaps.

These products are available in three package styles:

• SS461C: Flat TO-92-style package with straight leads in bulk packaging which allows for a compact PC board layout.

FEATURES

• Enhanced sensitivity
• Latching magnetics respond to alternating North and South poles
