SS361CT;SS461C;中文规格书,Datasheet资料.pdf

DESCRIPTION The SS361CT/SS461C latches are small, sensitive and These Hall-effect devices are available in two package styles: versatile digital Hall-effect devices that are operated by the the SS361CT in the miniature SOT-23 surface mount package magnetic field from a permanent magnet or an electromagnet. and the SS461C in the leaded, flat TO-92-style package. They are designed to respond to alternating North and South poles. The SS361CT’s small size requires less PCB (printed circuit board) space, allowing it to be used in smaller assemblies. These bipolar sensor ICs have enhanced sensitivity which often allows for the use of less expensive magnets. The SS361CT is available on tape and reel (3000 units per They offer reverse polarity protection and deliver a stable reel). The SS461C is available in a bulk package (1000 units output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature per bag). range. Operation from any dc supply voltage from 4 Vdc to 24 Vdc is acceptable. FEATURES AND BENEFITS POTENTIAL APPLICATIONS Enhanced sensitivity: will operate from only 50 Gauss Transportation typical, at 25°C [77 °F], 80 G max. at -40 °C to 85 °C Speed and RPM sensing [-40 °F to 185 °F], and 95 Gauss over the full temperature Tachometer, counter pickup range, allowing the use of smaller, potentially lower-cost Motor and fan control magnets or wider air gaps Electronic window lift Subminiature, SOT-23 surface mount package (SS361CT)
