TC-LB Miniature Load Button Load Cell
Product Description
TC-LB miniature load button overview
The TC-LB is a compression-only miniature load button load cell built from
17-4PH precipitation-hardened stainless steel, designed to measure compressive forces in the tightest and
most spatially constrained installations. Its flat, low-profile puck shape and small diameter allow it to be
placed between mating surfaces, inside fixtures, or beneath structural joints to capture contact and
compressive forces that no conventional load cell geometry could accommodate. Integrated #6-32 UNC mounting
threads make fixturing straightforward, and stainless steel construction with IP64 protection ensures
reliable performance in harsh and demanding environments. Available in capacities from 100 lbf to 10,000
lbf, the TC-LB is a direct improved-accuracy drop-in replacement for the FUTEK LLB400 series.
Typical applications
The TC-LB is commonly specified wherever a compression force needs to be
measured in a confined space where conventional load cell geometries cannot fit.
and the workpiece, measuring the actual compressive force being applied. This makes it a
practical tool for validating clamping forces in fixtures, monitoring press loads in stamping
and forming equipment, and setting up automated assembly presses.
TC-LB to be embedded directly into machine structures, test fixtures, and mechanical assemblies
where a protruding sensor would interfere with the system. Integrated mounting threads allow
secure, permanent installation without additional hardware.
directly into robotic end-effectors and grippers, measuring the actual contact force applied to
a workpiece during pick-and-place, assembly, or insertion tasks. This enables precise force
control without adding meaningful bulk or weight to the end-effector assembly.
TC-LB connects directly to PLCs, DAQ systems, and force indicators for real-time compression
monitoring, overload detection, and closed-loop force control in automated systems where space
precludes a larger sensor.
compression test needs to be performed in a location where a standard load cell body would not
physically fit, such as inside a housing, beneath a bolt head, or within a small test fixture on
a benchtop machine.
rating, the TC-LB withstands dust, light moisture, and the mechanical stresses of industrial and
laboratory environments where standard steel sensors would corrode or degrade over time.
Technical notes
The TC-LB is compression-only and must not be used in tension. Load must be
applied concentrically through the dome on the top face. Do not apply load inside the marked
exclusion zone around the mounting threads, as off-center or edge loading will produce inaccurate
readings and may damage the sensing element. For best results, ensure the mating surface is flat and
perpendicular to the axis of loading. The #6-32 UNC mounting threads allow the TC-LB to be screwed
securely into a fixture plate or machine structure for permanent installation.
The TC-LB operates at a rated excitation of 10V AC/DC (20V max) and produces
a 2 mV/V analog output signal via a shielded 4-conductor 28 AWG integrated cable (2 ft). It is
compatible with any standard force indicator, DAQ system, or PLC analog input accepting a mV/V
bridge signal. It is a verified improved-accuracy drop-in replacement for the full FUTEK LLB400
series across all matching capacities.
The TC-LB ships with a 2 ft shielded 4-conductor 28 AWG
integrated cable. Standard color code:
