DESCRIPTION
The SS361CT/SS461C latches are small, sensitive and versatile digital Hall-effect 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.

FEATURES AND BENEFITS
• Enhanced sensitivity: will operate from only 50 Gauss
   typical, at 25°C [77 °F], 80 G max. at -40 °C to 85 °C
   [-40 °F to 185 °F], and 95 Gauss over the full temperature
   range, allowing the use of smaller, potentially lower-cost
   magnets or wider air gaps
• Subminiature, SOT-23 surface mount package (SS361CT)
   supplied on tape and reel allows for a compact design with
   automated component placement, helping to reduce
   manufacturing costs
• Small, leaded, flat TO-92 package (SS461C) allows for a
   compact PCB layout
• Bipolar latching magnetics respond to alternating North
   and South poles, making these products well-suited for
   accurate speed sensing and RPM (revolutions per minute)
   measurement
• Wide operating voltage range of 4 Vdc to 24 Vdc makes
   these sensors useable in a wide range of applications
• Built-in reverse voltage capability enhances the protection
   of the sensor and the circuits with which it is used
• Robust design: will operate up to 125 °C [257 °F]
• RoHS-compliant materials meet Directive 2002/95/EC
