FEATURES

Single current sinking or current

sourcing linear output

Improved temperature stability

Three pin in-line printed circuit board

terminals

Standard .100 mounting centers

Laser trimmed thin film and thick film

resistors minimize sensitivity

variations and compensate for

temperature variations

Flux range of ±100 to ±2500 gauss

OPERATION

The SS9 utilizes a Hall effect integrated

circuit chip which provides increased

temperature stability and performance.

Laser trimmed thick film resistors on the

ceramic substrate and thin film resistors

on the integrated circuit reduce null and

gain shifts over temperature which results

in consistent sensitivity from one device

to the next.

† Derived from straight line between end points.

†† Silver coating on back of ceramic is electrically connected to – terminal.

Specified using a 2.2K resistor unless otherwise noted.

Null voltage (Vout at 0 gauss) and sensitivity are ratiometric to supply voltage.

Application consideration: The output is

clamped at the high end. Clamping voltage

may be as low as 9VDC. The output will not

exceed the clamping voltage regardless of

field strength or supply voltage.
