Leadership, in full force. Whether it’s critical applications
such as IV drips or dialysis, or serious engineering like robotic
end-effectors, Honeywell Sensing and Internet of Things (SIoT)
offers an unbeatable line of force sensor options. These sensors
measure the addition or backup of force — meaning, the
resistance of silicon-implanted piezoresistors increases when
flexed under applied force. Each sensor concentrates force
FEATURES
FSA Series.

• Total Error Band: ±5 %FSS • Accuracy:
±3 %FSS • Ratiometric analog or
SPI or I
2
C-compatible digital output
• Fully calibrated and temperature
compensated over 5°C to 50°C [41°F to
122°F] • Overforce: 6804 g [15 lb]
• Supply voltage: 3.3 Vdc typ. or 5.0 Vdc
typ. • Low power consumption: 13 mW
(analog) or 20 mW (digital) • Excellent
part-to-part repeatability • Enhanced
reliability • Stable interface plunger
• Internal diagnostic functions available
• REACH and RoHS compliant
Benefits: Choice of force ranges
maximizes sensitivity and improves
system resolution/performance.
Total Error Band enhances system
performance. Enhanced accuracy
includes all errors due to force
non-linearity, force hysteresis, and
non-repeatability. Digital output
enhances performance through
reduced conversion requirements
and convenience of direct interface to
microprocessors. Overforce provides
enhanced durability in applications
where overforce may exist. Supply
voltage provides customers flexibility
of design within the application.

Diagnostics functions allow user to
determine if sensor is working correctly
by detecting if electrical paths are broken
or shorted inside the sensor. Potential
medical applications include ambulatory
non-invasive pump pressure, infusion
pumps, kidney dialysis machines,
and occlusion detection. Potential
industrial applications include load and
compression sensing.
FSG Series.
Features: Extremely low deflection
(approx. 30 µm typical at Full Scale)
• Low repeatability error: ±0.2% span
Low linearity error: ±0.5% span • Low
off-center loading errors • Resolution to
0.0098 N • Fast response time
• Low power consumption • High ESD
resistance of 8 kV
Benefits: Extremely low deflection
helps reduce measurement error. Low
repeatability error improves overall
system accuracy. Low linearity error
improves system accuracy over the
entire force range. Low off-center
loading errors improve system accuracy
due to mechanical misalignment.
Low resolution improves customer’s
system accuracy. Fast response time
allows system to make faster decisions
which may improve system accuracy.
Low power consumption allows use
in battery applications. High ESD
resistance reduces special handling
during assembly. Potential medical
applications include infusion pumps,
ambulatory non-invasive pumps,
occlusion detection, kidney dialysis
machines, and enteral pumps; potential
industrial applications include load and
compression sensing, variable tension
control, robotic end-effectors, and wire
bonding equipment.
FSS Series.
Features: RoHS-compliant materials
• Low deflection • Direct mechanical

MCTF at 25°C [77°F] (subject to
application variation) • Small size
• Enhanced sensitivity without
compromising signal integrity
• Electrically ratiometric output • Low
voltage supply • High resistance
to electrostatic discharge (ESD)
Classification Level 3B (8 KV) • Sensor
output has low sensitivity to many
mounting stresses
Benefits: RoHS-compliant materials
allow use in industries requiring
regulation compliance. Low deflection
directly to the silicon-sensing element through a stainless steel
plunger, with the amount of resistance changing in proportion
to the amount of force applied. This change in circuit resistance
results in a corresponding output level. Honeywell SIoT force
sensors also deliver built-in stability and flexibility to provide
enhanced performance in most applications.
