TE Connectivity FX292X-100A-0100-L Load Cell, Compact Compression, 100 lb, 20 mV/V, 6 V

The TE Connectivity FX292X-100A-0100-L load cell is designed to operate with a recommended excitation voltage of 6 VDC. It is a ratiometric sensor, meaning its output signal (in mV/V) is directly proportional to both the applied force and the supplied voltage. Always ensure your signal conditioning circuitry is compatible with this voltage range.

This load cell provides an unamplified analog output of 20 mV/V. To read it with a microcontroller, you will need an instrumentation amplifier (like an HX711 module) to boost the small millivolt signal to a usable range. Connect the load cell's output wires to the amplifier's input, supply the recommended 6V excitation, and then interface the amplifier's output to your MCU's analog-to-digital converter (ADC) pin.

A compression load cell, like the FX292X, is specifically designed to measure forces that push directly onto its sensing surface along its primary axis. It is not suitable for tensile (pulling) forces. Other types, like tension or universal load cells, are engineered for different loading modes. Always ensure the force application matches the sensor's designated loading direction.

The FX292X-100A-0100-L is rated for reliable operation within an ambient temperature range of 0°C to 50°C. Performance specifications, including zero point and sensitivity, are guaranteed within this range. For use outside these limits, consult the manufacturer's datasheet for derating information and potential effects on accuracy.
