Original SRI 6-Axis Force Torque Sensor - High Precision for Humanoid Robots

Sunrise Instruments (SRI) is a world-leading manufacturer of multi-axis force sensors. Their 6-axis force/torque sensors are specifically engineered for demanding robotic force control tasks. Using advanced strain bridge technology and precision decoupling algorithms, SRI sensors provide real-time calculation of forces and torques across three-dimensional space.

Building on decades of experience in the auto-crash testing industry—where precision is paramount—SRI sensors excel in humanoid robot joint control, intelligent floating grinding, and aerospace testing. SRI has become a strategic partner for major robot manufacturers worldwide by offering high-end performance as a reliable alternative to Western brands.

Product Highlights

Exceptional Cost-Performance: Delivers performance comparable to top international brands at a significantly lower acquisition cost.
Specialized Humanoid Models: Features the M37 and M38 series—ultra-light and low-profile designs optimized for humanoid ankle balance and wrist manipulation.
Superior Decoupling Accuracy: Proprietary static and dynamic calibration algorithms ensure minimal crosstalk and highly reliable measurement data.
Intelligent Integrated Modules: Select models support built-in digital output (EtherCAT, CAN, RS485), providing direct physical units and simplifying integration.
Industry-Wide Versatility: A comprehensive model range spanning from 10mm medical-grade micro-sensors to industrial units with multi-ton capacities.
iGrinder® Smart Ecosystem: Seamlessly integrates with SRI's iGrinder® floating heads for complete closed-loop automated grinding solutions.

Intelligent Grinding & Polishing: Used with the iGrinder® system to achieve surface finishing under constant pressure on complex surfaces.
Automotive Crash Testing: Analyzing impact forces on dummy models and vehicle structures (SRI holds a leading global position in this field).
Medical Surgical Assistance: Micro-sensors used in surgical tools to perceive tissue resistance and enhance surgical safety.
Aerospace & Defense: Wind tunnel testing, payload distribution analysis, and space robotic arm docking experiments.

Frequently Asked Questions

Q: What are the advantages of SRI compared to ATI (USA)?

A: SRI offers greater flexibility in range coverage and customization speed, with faster technical response and after-sales support in Asia-Pacific, combined with extreme cost-effectiveness.

Q: Are the products officially calibrated?

A: Yes. Every SRI sensor is calibrated on a professional multi-axis force calibration platform before shipping. An official Calibration Certificate with matrix coefficients is provided.

Q: How do I use SRI sensors in my control system?

A: We provide specialized Interface Boxes supporting major communication protocols. For developers, we also provide SDKs for C++/Python and ROS drivers.

Q: What is the overload capacity?

A: SRI sensors are designed with a safety overload factor of over 300%. During normal use, minor collisions caused by programming errors will not damage the sensor.

Q: What is the typical lead time?

A: Standard industrial series are often in stock or ship within 2-3 weeks. Specialized low-profile models for humanoid robots typically have a lead time of 4-6 weeks.
