SOP SOPMK-001 50kg Load Cell Sensor - 2.0mV/V, 0.1%F.S, Alloy Steel

The SOPMK-001 load cell requires a DC excitation voltage between 5V and 10V. Operating within this range ensures the strain gauge bridge is properly powered and the specified 2.0mV/V output sensitivity is achieved. Exceeding the maximum 10V excitation can damage the internal strain gauges.

This load cell outputs a low-level millivolt signal and cannot be connected directly to a microcontroller. You must use a dedicated load cell amplifier or HX711-based module. The amplifier connects to the load cell's 4-wire (or 6-wire with sense) output, provides the excitation voltage, and amplifies the differential signal to a readable analog or digital output for your controller.

Nonlinearity (0.1% F.S.) refers to the maximum deviation of the sensor's output curve from a straight line between zero and full load. Hysteresis (0.03% F.S.) is the maximum difference in output when the same load is approached from increasing versus decreasing weight directions. Both are critical for overall measurement accuracy and repeatability.

Yes, this cantilever beam load cell is fundamentally a force transducer. While commonly used for weighing, it can measure any applied force up to 50kg (approx. 490 Newtons) along its designated axis, such as tension, compression, or push/pull forces in mechanical testing, process control, or robotic end-effector feedback systems.

For accurate results, the load cell must be firmly fixed at its base (the end with mounting holes) to an immovable structure. The load should be applied precisely at the designated point on the free end. Avoid side loads or moments not aligned with the sensing axis, as they can cause measurement errors and potentially damage the sensor.
