Fingertip force feedback begins at the contact pad
The MT-BLC-SUB family supports axial compression sensing behind a contact pad. Keep tangential loads out of the sensor, define a hard stop and test the full finger motion for cable strain. Surgical instrument developers should specify cleaning exposure, isolation needs and any sterilisation process before a configuration is proposed.
Pump occlusion sensing requires a mechanism model
Button load cells in medical devices measure the reaction force at a mechanical interface. Syringe geometry, friction, tube stiffness and drive alignment affect how that force relates to fluid pressure. Use MT-BLC-MED for OEM integration and validate thresholds on the complete device.
Define the qualification evidence before samples
Specify zero drift, temperature conditions, overload, expected cycles and lot traceability. Ask for an agreed test plan and configuration records. Do not infer medical certification or sterilisation suitability from the miniature sensor form factor.

Before you freeze the drawingFive questions about
Five questions about
compression measurement.
Need an application-specific answer?
Talk through your force path ↗
How do I choose a button load cell capacity?
Include preload, normal compression peaks and credible overloads. Select a range that resolves the minimum force of interest while leaving mechanical margin, and add a fixture overload stop.
Are kg, kgf and N interchangeable?
Kilograms describe mass. Use kgf when expressing force: 1 kgf = 9.80665 N. The tables show N, kgf and lbf together; dimensions and ratings remain model-specific.
Can you supply a drop-in replacement?
Send the complete original model, drawing revision, capacity and electronics details. We review mechanical and electrical interfaces and agree a sample correlation test before compatibility is confirmed.
Does a high-temperature cable upgrade change the sensor rating?
No. Cable, sensor body and amplifier ratings are separate. Request a +150°C or +200°C sensing configuration with the actual thermal conditions and agreed zero/span limits.
Can a load button connect directly to a PLC?
A bare mV/V bridge normally needs a compatible conditioner. Specify an MT-AMP-KIT with 0–10V, 4–20mA or an agreed RS485 interface, plus system calibration and force mapping.
