1 3.8 to 30 VDC supply voltage range
1 High output current capability of
50 mA absolute maximum
SS100 Series
The temperature compensated Hall effect
sensor consists of a quad Hall sensing
element in a square integrated circuit
chip, which is then encapsulated in a
glass-filled thermoset molding material.
The small SOT89 style package surface
mounts on PC boards and flexible
circuits.
The integrated circuit is thermally balanced for predictable performance over
the full temperature range of –40 to
F125°C. Built-in temperature compensation has a negative slope (operate and
release points decrease as temperature
increases). This slope is optimized to
match the negative temperature coefficient of low cost magnets, to track their
performance over temperature. Bipolar,
unipolar and latching magnetics are
available.
Band gap regulation provides extremely
stable operation over the full supply voltage range of 3.8 to 30 VDC. Current consumption is a low 10 mA maximum.
SS100 sensors are capable of continuous
20 mA sinking output, and can withstand
temporary current as high as 50 mA absolute maximum. They can use existing
power supply sources in most applications, and can be directly interfaced with
many electronic components without buffering or compensation circuitry. SS100
Series sensors are available on tape and
reel for high-volume, automated pick and
place equipment. Each reel contains
1,000 sensors.
NOTE: DO NOT wave solder this product. This process may negatively affect
sensor performance and reliability, and
will void MICRO SWITCH’s warranty.
MICRO SWITCH recommends a convection infrared reflow process with peak
temperatures not to exceed 220°C
(428°F) for 10 seconds maximum.

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