SparkFun Electronics will be closed on November 26, 2020 and November 27, 2020 for the Thanksgiving holiday. We will begin normal operations at 9:00 AM Mountain Time on November 30, 2020.
This miniature straight bar load cell (sometimes called a strain gauge) can translate up to 100g of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar. With this gauge you will be able to tell just how heavy an object is, if an object's weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.
Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 100g. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows: red = Exc+, green = Sig+, black = Exc-, and white = Sig-. Additionally, these load cells offer an IP65 protection rating and features four M3 sized through-holes for mounting purposes.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Based on 1 ratings:
it is made in China. The wires where they attach to the load cell are very delicate and easily broken so be careful. Two of the 4 holes are not tapped but they should be. Not as linear as an expensive load cell but look at the price. It's worth the cost for sure.
