Honeywell SS40AF

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℃ to 125℃ [- 40°F to 257°F] temperature range. Operation from any dc supply voltage from 4.5 Vdc to 24.0 Vdc is acceptable. 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.
