SS520 Series Dual Hall-effect Digital Position

Sensors with speed & direction outputs

Sensing and Control

The Speed & Direction Hall-effect sensor has two distinct Hall sensing elements

precisely located 1.4 mm apart on a single integrated circuit chip, which is then

encapsulated in a thermoset molding material. Two active Hall latches provide

indication of the speed and direction of a magnetic gradient across the face of

the package, such as the gradient from a rotating ring magnet. The small, 4-pin

SOT89 style package surface mounts on PC boards and flexible circuits.

Built-in temperature compensation is optimized to match the temperature coeffi-

cient of low cost magnets and track their performance over temperature.

Latching magnetics are standard for reliable operation.

A novel regulator circuit provides extremely stable operation with supply volt-

ages as low as 3.4 Vdc and as high as 24 Vdc. A typical room temperature cur-

rent consumption of 7.5 mA helps conserve power in battery operation. SS520

series sensors can use existing power supply sources in most applications, and

can be directly interfaced with many electronic components without buffering or

compensation circuitry.

GENERAL DESCRIPTION

l Single miniature plastic package

l Frequency signal for speed out-

l Logic level (High or Low) signal

l Temperature compensated mag-

l Functionality of two discrete Hall

l Symmetry of operate/release

l Low current consumption

l Wide operating voltage range

FEATURES

DO NOT wave solder this product.

Wave soldering may negatively affect the sensor performance and reliability.

Subjecting the sensor to wave soldering will void Honeywell’s warranty.

Interruption of power to a latching device may cause the output to change

state when power is restored. If a magnetic field of sufficient strength is pres-

ent, the sensor output will be in the condition dictated by the magnetic field.

CAUTION

WAVE SOLDER DAMAGE

Failure to comply with these instructions may result in product damage.
