Overview
The SS361RT and SS461R are small, versatile, digital Hall-effect sensor ICs that are operated by the magnetic field from a permanent magnet or an electromagnet, and designed to respond to alternating North and South poles. The SS361RT is turned on by a North pole while the SS461R is turned on by a South pole.
These latching digital Hall-effect sensor ICs have enhanced sensitivity of only 50 G typical, at 25°C [77 °F] that often allows for the use of less expensive magnets or wider air gaps. They offer a robust IC design with reverse polarity protection and 150 °C [302 °F] capability.
These product are available in two package styles:
- SS361RT: Subminiature SOT-23 surface-mount package on pocket tape and reel which allows for compact design with automated component placement.
- SS461R: Flat TO-92-style package with straight leads in bulk packaging which allows for a compact PC board layout.
