Micro Button Load Cell


Applied Measurements CDFT micro button load cell is designed for compression measurement applications where the absolute minimum of space is available for transducer mounting.

With capacities from 10N to 250N available and measuring just 9mm in diameter and 2.9mm in height, the CDFT is the smallest standard button load cell that we offer.  If you need to measure lower or higher forces, the CDFM3 miniature button load cell is available in capacities from 0-100N right up 0-20kN and is slightly larger at 30mm diameter and 12mm in height.

Applied Measurements CDFT micro button load cell is ideal for retro-fitment and is ideal to use in robotics and effectors, hoist and winch loads, micro-component assembly tools and machinery, keyboard button and telephone control and mechanical switches.

*The resonant frequency is calculated with the body of the load cell attached to a large plate, ensuring that only the sensing element oscillates. This is vital to achieve the highest natural frequency and subsequent frequency response.
