FX29
Compact Compression Load Cell
Versatile Miniature Force Sensor
mV, Amplified, and Digital Outputs
Low Power Consumption
Rugged Microfused Sensing Element
Stainless Steel Enclosure
Several Load Ranges
TE Connectivity’s (TE) FX29 is a compact compression load cell
that offers exceptional price-to-performance in a robust sensor
package. Optimized for embedded force sensing applications from
disposable medical devices to durable appliances and exercise
equipment. The FX29 allows design flexibility with mV, amplified,
and digital output options.
Features
• Compact Design
The FX29 incorporates the high reliability Microfused technology
and is offered in ranges from 10lbf to 200lbf (50N to 1000N).
Microfused technology provides excellent span and zero stability,
outstanding cycle life, superior resolution, high over-range
capabilities, and an unamplified span sensitivity of 20mV/V.
• mV or Amplified Analog Outputs
• Optional I2C Digital Interface
• High Over Range Capability
The FX29 utilizes a two-piece construction of stainless steel
materials. The combination of a metal injection molded flexure and
micro miniaturized MEMS strain gauges allows flexibility of force
range options for a lower cost sensor. These improvements over
previous load cell designs give the FX29 more precise
dimensional control and better performance.
Applications
• Medical Infusion Pumps
• Analog & Digital Scales
• Fitness & Exercise Equipment
• Payload Weighing
• Power Tools
• Robotics
• Surgical & Dental Tools
• Battery Powered Devices
• Manufacturing Equipment

Mounting Recommendation
The sensor can be put into a simple slot fixture for load testing. The load should be applied to the spherical face
of center boss. Recommended to stick the sensor with double face 3M adhesive or glue. Some feature to clamp
the sensor from top to down can be optional.
See below for reference:
NOTE: Clamping force may shift the zero reading slightly. Re-zero if needed.
Below table shown the Zero change difference when loaded 5 Lbf from the top. (For reference only)
