6-axis Force Sensor For Industrial Robot
6-axis Force Sensor For Industrial Robot
The BGTT series is a medium-range analog six-axis force sensor with a titanium alloy hollow ring structure. It has two wiring
methods: inside the ring and outside the ring, which can adapt to different assembly application requirements.
The choice of titanium alloy ensures the sensor combines high
rigidity with low mass. The sensor boasts high resolution, low
coupling, high precision, and a high level of protection, making it suitable for robotic force-controlled grinding, assembly, drag
teaching, and scientific research testing.
When used with NST series data collectors, the sensor can support multiple communication interfaces such as EtherCat, EtherNet,
RS485/RS232, CAN, and USB.

Application advantages of six-dimensional force sensors in manufacturing
Digital six-axis force sensors demonstrate strong adaptability in various application scenarios. In industrial robotics, assembly robots use six-axis force sensors to sense the three-dimensional components of bearing press-fitting forces, enabling “force-controlled assembly.” When excessive torque is detected, they automatically adjust their posture to avoid component damage, achieving assembly accuracy down to 0.01mm. Grinding robots utilize six-axis force feedback to adjust grinding head pressure in real time, maintaining a surface roughness of less than Ra0.8µm on curved workpieces. Collaborative robots, integrated with these sensors, can detect the magnitude and direction of collision forces and trigger an emergency stop within 50ms, ensuring safe human-robot collaboration.
In high-end manufacturing, the precision grinding process of aircraft engine blades relies on six-axis force sensors for real-time monitoring of grinding forces, enabling adaptive feeds in conjunction with CNC systems. Semiconductor packaging equipment uses micro six-axis force sensors (with a range of ±10N) to sense chip bonding forces, ensuring consistent strength during gold wire ball bonding. In scientific research, their precise measurement capabilities are essential for measuring the three-dimensional forces of joint motion in biomechanics experiments and analyzing the strain state of components under complex loads in material mechanics testing.

Introduction of overload capacity, which is a point of concern for multi-di.mensional force sensor customers.lt is also an important cause of sensordamage.(The sensor value is high, please contact our engineer for selection)
1. The selection of the range does not only consider the applied externalforce, but also the self-weight of the fixture and the workpiece, as well asthe bending moment generated by it.
2. The overall size of the sensor should be similar to the size of the work-piece fixture.
