Hall-Effect Digital Sensors offer high sensitivity.
March 11, 2010 -
Bipolar Latching Hall-Effect Digital Sensor ICs include models SS361CT with subminiature SOT-23 surface-mount package, and SS461C with leaded, flat TO-92 package. They operate from 50 Gauss typical at 77°F, 80 Gauss at -40 to +185°F, and 95 Gauss over -40 to +257°F. Operating from 4-24 Vdc, ICs include built-in reverse voltage capability that provides protection of sensor and circuits. Applications include speed and rpm sensing, tachometers, counter pick-up, and motor and fan control.

Honeywell's New High-Sensitivity Bipolar Latching Hall-Effect Digital Sensor ICs Help Reduce Total Manufacturing Costs
MINNEAPOLIS - Honeywell (NYSE: HON) today announced the introduction of new high-sensitivity Bipolar Latching Hall-Effect Digital Sensor integrated circuits (ICs) for use in a variety of transportation, industrial, commercial, and medical applications.
The enhanced sensitivity of Honeywell's new SS361CT and SS461C Bipolar Latching Hall-Effect Digital Sensor ICs allows for the use of less expensive magnets, helping to reduce total production costs for manufacturers. The new devices are very sensitive, operating 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 max. over the full temperature range of -40°C to 125°C [-40°F to 257°F]. As bipolar latching devices, these sensors respond to alternating North and South poles.
Honeywell has downsized the sensor's integrated circuit, saving on manufacturing costs while still meeting customer requirements. These manufacturing cost savings result in lower costs to customers. The SS361CT and SS461C deliver a stable output over a -40°C to 125°C [-40°F to 257°F] temperature range, and operate from 4 Vdc to 24 Vdc. Built-in reverse voltage capability enhances protection of the sensor and the circuits.
The SS361CT's subminiature SOT-23 surface mount package uses less space on the printed circuit board than standard Hall-effect sensor packages such as TO-92 or SOT-89, allowing for use in smaller assemblies. Additionally, the SS361CT is supplied on tape and reel, allowing for automated, lower-cost pick and place assembly which can help reduce manufacturing costs. The SS461C's leaded, flat TO-92 package is available in bulk packaging (1000 units per bag).
Potential transportation applications for the SS361CT and SS461C include speed and RPM (revolutions per minute) sensing, tachometers, counter pick-up, motor and fan control, electric window lifts, and convertible roof position. Potential industrial/commercial applications include flow-rate sensing for appliances such as coffee makers, speed and RPM sensing, tachometers, counter pick-up, brushless dc motor commutation, motor and fan control, and robotics control. Potential medical applications include medical equipment using electric motors.
