Press force window
Specify peak pressing force, minimum force of interest, cycle speed and a mechanical overload stop. Select the amplifier bandwidth with the cycle.
MT-BLC-LBM / SERIES
Standard Miniature Compression Load Button
Heat treated stainless steel load buttons for press tooling, clamping fixtures, bearing preload and battery expansion fixtures. Match the load path, base support and overload window before choosing capacity.

Series options are not a full cross-product of every dimension and capacity. Button radius, tolerances, overload and model-specific performance are confirmed on the released drawing and quotation.
Measure compression without rebuilding the fixture.
Bearing preload
Account for the assembly preload and the operating force together. A zeroed display does not remove physical load from the sensor.
Battery expansion
Describe the fixture stiffness, expected displacement and test temperature. Long-term zero stability must be qualified with the assembled fixture.

The load path mattersLoad the convex button.
Load the convex button.
Give the cable room to move.
A compact sensor only measures correctly when the surrounding fixture supports it correctly.
Support the intended base surface
Machine a rigid, flat seat from the exact outline. Locate the sensor without squeezing the case or bypassing the sensing load path.
Keep contact on the central button
Align compression with the sensing axis. Keep the tool clear of the cover and outer case; a spherical top helps accommodate small alignment differences.
Relieve the fine shielded cable
Provide a dedicated exit channel and jacket retention. Specify flexing, bend space and a strain-relief spring or sleeve with the configuration.
