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.

Button Load Cell Mounting & Engineering Guides
Practical engineering notes for compact compression measurement. Start with the mounting recess, then check force units and the amplifier requirements.

Keep force on the central convex button
A recess should locate the sensor without pinching the body or trapping the cable. Use the exact model drawing to identify its intended base support surface. Do not press on the cover or outer case, and do not copy another model’s recess dimensions.
1 kgf = 9.80665 N; 1 lbf ≈ 4.44822 N
N, kgf and lbf are force units. Kilograms describe mass; a search for a 1kg, 10kg or 200kg button load cell usually needs its intended force range clarified. The catalog reports N / kgf / lbf together to make that selection explicit.
1–2 mV/V needs a low-noise bridge input
At 5 V excitation, a nominal 2 mV/V sensor produces about 10 mV at full rated force. Confirm amplifier input range, excitation, shielding, grounding and filtering. Avoid routing the cable alongside motor power wiring.

Give the cable room to move.
A compact sensor only measures correctly when the surrounding fixture supports it correctly.
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.

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.
