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).
