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.
These bipolar sensor ICs have enhanced sensitivity which
often allows for the use of less expensive magnets.
They offer reverse polarity protection and deliver a stable
output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature
range. Operation from any dc supply voltage from 4 Vdc to
24 Vdc is acceptable.
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
These Hall-effect devices are available in two package styles:
the SS361CT in the miniature SOT-23 surface mount package
and the SS461C in the leaded, flat TO-92-style package.
The SS361CT’s small size requires less PCB (printed circuit
board) space, allowing it to be used in smaller assemblies.
The SS361CT is available on tape and reel (3000 units per
reel). The SS461C is available in a bulk package (1000 units
per bag).
