Bipolar Position Sensor ICs
SS30AT, SS40A, SS50AT
Low-cost bipolar Hall-effect digital sensor ICs. SOT-23 (SS30AT), flat TO-92-style (SS40A), SOT-89B (SS50AT) packages. Digital sinking output.
The SS30AT/SS40A/SS50AT Series sensors are versatile, bipolar, Hall-effect sensors. These sensitive magnetic sensors offer reverse polarity protection and deliver stable output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature range. Operation from any dc supply voltage from 4.5 Vdc to 24.0 Vdc is acceptable.
The SS30AT/SS40A/SS50AT Series sensors build upon Honeywell’s popular magnetic position sensors and offer several advantages. These sensors have been designed with the latest technologies to provide reliable, cost-effective solutions to many commercial, computer, medical, and/or consumer applications requiring motor control and RPM sensing.
These products are available in three package styles to suit a variety of applications. The SS40A in the leaded, flat TO-92 style package can be supplied in bulk (1000 pieces per bag) or on tape in an “Ammopack” (fan-fold) format. The SS30AT in the subminiature SOT-23 surface-mount package, and the SS50AT in the small SOT-89B surface-mount package, are both supplied on tape and reel for use in automated pick-and-place equipment.
The surface mount versions are mounted directly on the electrical traces on a printed circuit board (PCB). They are attached by an automatic solder reflow operation which requires no hole, so it may help reduce the cost of the PCB.
