Mounting Devices

A variety of convenient fiber mounting devices are available in two lengths and two shaft diameters.

Length:

  • The 32mm length is ideal for standard, isometric forces.
  • Choose the 22mm length when using a motor.

Shaft diameter :

  • Use the 0.8mm for the KG4 and KG7B force transducers.
  • Use the 0.5mm for the KG4A and KG7.

The KG2 have unique mounting devices.
