Miniature 3D Load Cell 1kg 2kg Multi-Axis Sensor

The LCM3B Miniature 3D Load Cell is a highly compact and versatile force sensor designed for precise multi-axis force measurements. With a footprint of just 40 x 40 mm and a low profile height of only 20 mm, it is well-suited for space-constrained environments. Constructed from lightweight aluminum, the LCM3B is available in rated capacities of 1kg(10N) and 2kg(20N), making it ideal for delicate and precision applications.

What sets the 3-axis load cell LCM3B apart is its ability to measure forces along three mutually perpendicular axes (Fx, Fy, Fz) simultaneously—without requiring complex mathematical conversions or signal processing. Each axis integrates a Wheatstone full-bridge circuit with 500 ohms resistance, which not only enhances signal stability but also reduces power consumption compared to the more common 350-ohm bridge configurations. The sensor supports both tension and compression loading in all three directions. By default, it provides positive output under compression and negative output under traction, though this can be customized as needed.

The precision and responsiveness of the LCM3B make it a valuable tool across a wide range of industrial, medical, and research applications. Below are eight key areas where this miniature multi-axis force sensor is particularly effective:

• Robotic Arm Force Feedback

The LCM3B allows robotic systems to detect and respond to multi-directional forces, enabling smoother, safer, and more accurate movements, especially in micro force detection applications.

• Gripper Force Measurement

For robotic or automated grippers, accurate force measurement in three axes ensures controlled handling of delicate or irregularly shaped items without causing damage.

• Medical Simulators

In surgical or training simulators, the LCM3B enables realistic tactile feedback by sensing subtle force interactions, thereby enhancing realism for medical trainees.

• Surgical Tool Force Sensing

Precision is paramount in surgical robotics. The LCM3B offers real-time force feedback, improving the control and safety of minimally invasive surgical tools.

• Micro-Assembly Force Monitoring

In manufacturing processes involving tiny or fragile components, such as electronics or optics, the LCM3B ensures that applied forces stay within strict tolerances.

• Biomechanics Research

Researchers studying human motion or muscular forces benefit from the LCM3B’s high-resolution measurement capabilities to monitor force patterns in multiple directions.

• Anti-Collision Sensing in Collaborative Robots (Cobots)

To enhance safety in human-robot interaction, the sensor can detect even minor forces resulting from accidental contact, triggering immediate shutdown or avoidance protocols.

• Biomedical Haptic Feedback Systems

The LCM3B is ideal for use in haptic feedback mechanisms in rehabilitation and assistive devices, where detecting subtle touch and force variations is critical.

In addition to its standard configuration, we offer custom design services to tailor the LCM3B tri-axial load cell to specific integration requirements. Whether you're working on an advanced research project or developing next-generation medical or robotic equipment, this miniature 3D load cell delivers high-performance sensing in a compact, power-efficient package.
