Solid State Sensors
Surface Mount Digital Position Sensors
FEATURES
Quad Hall design virtually eliminates
mechanical stress effects
Temperature compensated
magnetics
Bipolar, unipolar, latching magnetics
Super high sensitivity available
Symmetry of operate/release points
about zero gauss (bipolar/latching)
Operating temperature range of –40
to 125°C
Low current consumption (7 mA
typical @ 5 V, 25°C)
3.8 to 30 VDC supply voltage range
High output current capability of
50 mA absolute maximum
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 bal-
anced for predictable performance over
the full temperature range of –40 to
125°C. Built-in temperature compensa-
tion has a negative slope (operate and
release points decrease as temperature
increases). This slope is optimized to
match the negative temperature coeffi-
cient of low cost magnets, to track their
performance over temperature. Bipolar,
unipolar and latching magnetics are
available.
SS100 Series
Band gap regulation provides extremely
stable operation over the full supply volt-
age range of 3.8 to 30 VDC. Current con-
sumption 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 abso-
lute maximum. They can use existing
power supply sources in most applica-
tions, and can be directly interfaced with
many electronic components without buf-
fering 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 prod-
uct.
This process may negatively affect
sensor performance and reliability, and
will void MICRO SWITCH’s warranty.
MICRO SWITCH recommends a convec-
tion infrared reflow process with peak
temperatures not to exceed 220°C
(428°F) for 10 seconds maximum.
