The SS40A/SS50AT Series sensors are low-cost, 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 SS40A/SS50AT Series sensors build upon Honeywell’s popular

magnetic position sensors and offer several competitive advantages. These

sensors have been designed with the latest technologies to provide reliable,

cost-effective solutions to commercial, computer, medical, and/or consumer

applications requiring motor control and RPM sensing.

These products are available in a variety of package styles to suit a

number of applications. Ammopack versions, along with tape-and-reel, are

standard. The surface mount version is mounted directly on the electrical

traces on a PC (printed circuit) board. It is attached by an automatic solder

reflow operation which requires no hole, so it reduces the cost of the PC

board
