Home / Load Cells / MR-251
"MR-251" / Ultra-small type
Features
- Ultra-small & low capacity, namely, 12 mm in external diameter and 4 mm in thickness (4.2 mm per 50N).
- Load can be sensed on the flat surface of 8 mm in diameter (during uniform loading).
- Capacities: 20N & 50N.
- Applications: Most suitable for measurement of finger pressure sensibility, for example, measurement of IC/vacuum chuck pressurizing force, body pressure distribution on car seats, and so on.

*RE: Cable
An extremely thin side wound shielded cable with an excellent bendability is used in this Model of Load Cell. In order for this extremely thin cable to be free from any accidents of being snapped off in the course of operation, it is recommended that this thin cable is connected with the robot cable via relay terminals if the load cell is installed on fluctuating positions.
Although the standard length of the drawn out cable from the load cell is determined to be 3 M, we see no particular effects provided even that the load cells are used with the drawn out cable in the different lengths
