Product overview
Beam body and cable exit
A rectangular beam carries upper mounting openings and a circular side cover. A spring-protected cable exits from the end face.
Shear-beam arrangement
One end is fixed and the other end receives the load.
| Sensitivity | 2.0 ±0.05 mV/V |
|---|---|
| Input resistance | 380 ±30 Ω |
| Output resistance | 350 ±5 Ω |
Beam and mounting dimensions by capacity
L3 locates the first hole; L4 and L5 give successive centre spacings. ØD and ØD1 describe the stepped hole, while ØD2 applies to the other two holes. Dimensional units require confirmation. Confirm the stepped-hole dimensions and mounting spacings for your selected capacity before designing the fixture.
