Subminiature Load Buttons for Ø6–Ø10 mm Spaces
For a tiny load cell, the surrounding mechanism matters as much as the sensor. Compare outside diameter, installed height, loading contact and the cable relief before choosing a force range.

Start with OD × height, then allow cable clearance
The MT-BLC-SUB design envelope starts at Ø6 mm × H2.8 mm, with Ø8 and Ø9.5 mm options. These are series options rather than a promise that every force rating fits every envelope.
- Send the maximum installed diameter and total height, including the loading contact.
- Show the cable exit direction and the minimum bend space.
- Request the exact capacity-specific outline and spherical button radius.
1–250 N capacity options for small contact forces
A lower capacity can improve sensitivity to small load changes, but it must survive the actual preload, contact peaks and fixture setup. Define the overload stop and maximum expected force before reducing the sensor range.

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.

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.
