PRICING NOTICE
The pricing listed on our website is only for U.S. buyers and all pricing is subject to change without notice. Any inquiries for products from buyers outside of the U.S. will receive a quote and availability from the licensed distributor nearest your region. These prices will be based on product availability, currency conversions, markets, taxes, shipping costs, as well as local support.
3A40 3-Axis Load Cell
3-Axis Force Measurement
Force: 0.45 lbf to 11.2 lbf
Force: 2 N to 50 N
Model 3A40 has 3 independent axes in a small package size. Capacities available are 2N, 10N, 20N, and 50N. Product is made from aluminum alloy so it is very light weight.
Interface’s 3A40 3-axis load cell measures forces simultaneously in 3 mutually perpendicular axes: X, Y, and Z – positive and negative. Each axis provides a unique mV/V output and requires no mathematical manipulation. The 3-axis load cell is built to minimize eccentric loading effects and crosstalk between axes.
The 3A40 is ideally suited to many industrial and scientific applications, such as aerospace, robotics, automotive and medical research (orthopedics and bio-mechanical). The load cell is provided in various capacity ranges and sizes with each of the three axes providing the same capacity.
We are happy to work with your design needs – providing a custom design if warranted for varying capacities (between X, Y, and Z), higher temperature capability, or OEM/private labeling if needed.
