HOW TO INTERPRET CURRENT SENSOR SPECIFICATIONS
The following definitions will help the user
understand the characteristics of the
MICRO SWITCH current sensor line.
Adjustable Operating Range — The ad-
justable linear current sensors give the
user the option of changing the sensitivity
according to the maximum sensed cur-
rent of the application. The on-board sen-
sitivity adjustment allows the user to alter
the amplification of the Hall effect sensor,
thereby adjusting the amount of sensed
current needed to achieve maximum out-
put voltage.
Example
Voffset
Vo maximum
Vspan available
Assume a current maximum of 45 amps is
determined. The user would then apply
45 amps through the toroid and adjust the
sensitivity where indicated until a 9 volt
output is achieved. The sensitivity is then
determined as (3V)/(45A)
design allows for maximum sensor flex-
ibility.
For best results, choose a sensor to oper-
ate toward its maximum operate range.
Increased amplification occurs when the
sensor is adjusted toward its minimum
operate range. Any circuit noise is also
amplified.
Offset Shift — The offset shift refers to the
effect of temperature on the offset volt-
age. It is defined as a percentage of read-
ing per degree Celsius. Example: Offset
voltage is 6.0V at 25 C. The offset shift is
at 35 C is 6.0V
temperature increases as the device is
operated toward the temperature ex-
tremes.
Offset Voltage — The offset voltage is the
voltage output when no current is flowing
through the current carrying conductor.
This is also known as the null voltage.
Operate Current — The operate current
is the level of current required to cause a
change in logic state from the state at no
current flow. For example, the logic out-
put is high at no current flow. When the
current level is increased to the operate
point, the logic output goes low.
Ratiometric — Characteristics vary in
proportion to supply voltage.

Release Current — The release current
is the level of current required to cause a
change in logic state as the current flow
decreases from the operate point.
Response Time (linear) — Measured
from the time the input current reaches
90% of its full scale value to the time when
the sensor output reaches 90% of final
value. This assumes rise time of 1 micro-
second or less on input.
Response Time (digital) — The length of
time it takes the output to switch to within
ten percent of the supply voltage from the
negative supply after the rated operate
point is reached on the input. Measured
time will vary proportionally with the over-
drive current.
Sensed Current (Amps Peak) — The
SS94A1 and 91SS12-2 linear output Hall
effect sensors have a maximum sensed
range. The toroid (flux collector) in each
holder assembly has a gap in which the
sensor is placed. By varying the width of
the gap (lg), the level of current that pro-
duces the amount of gauss necessary to
saturate the sensor is varied. In other
words, the maximum/minimum output of
the Hall element will always be obtained
at rated gauss excitation. The current lev-
el needed to achieve that maximum/mini-
mum output depends on the width of the
gap in the flux collector. Max sensed cur-
rent is also affected by number of times
sensed current wire is looped thru sensor
hole. If max sensed current is 100 amps
and current wire is looped thru hole twice,
max sensed current drops to 50 amps.
Looped 4 times it drops to 25 amps, 5
times to 20 amps.
Sensitivity – The change in sensor out-
put to 1 amp change in input. Units are in
units/NI where N is number of times
sensed current wire is looped thru sensor
hole. For example, if sensed current wire
is looped thru hole twice then sensitivity
doubles; looped thru 3 times, sensitivity
triples, etc.
Temperature Range — The –25
ature range that the current sensor has
been rated. The performance specifica-
tions are not considered to be valid out-
side the specified temperature range.
