Simple magnetic encoder
Flow-rate sensor
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.

*Absolute maximum ratings are the extreme limits the device will withstand without damage to the device. However, the
electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating
conditions) are approached, nor will the device necessarily operate at absolute maximum ratings.
