te.com 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.

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.
