At TE Connectivity (TE), we believe that as the need for industrial robotic automation advances, sensing technology will continue to be the foundation for data collection that will help transform manufacturing floors into the connected, cost-effective, and reliable factories of the future. In fact, TE is future ready in robotics. We understand that the greater flexibility and precision that robotic systems demand requires more flexibility and even more reliable connectivity solutions. From automotive and aircraft construction to the pharmaceutical industry to logistics and metal processing, the latest generation of industrial robots can handle even more complex tasks. In these robotic environments, connections can't fail. TE offers numerous force, temperature, pressure, and position sensors that provide highly accurate measurements for precise movement control and accurate monitoring of system components for preventative maintenance. TE can help you meet the challenges your design engineers face. The Challenge: Accuracy and Precision As the robotics revolution takes hold, most manufacturers are finding that they need to build accurate and precise sensing elements into robotic equipment to help them handle the challenges of the factory floor. As an example, for collaborative applications, sensing systems must not only detect if a human is around but also prevent any possible collision between the robot and nearby workers. Sophisticated sensor technologies are a core requirement yet meeting these design requirements is not easy. Most environments require variable sensing ranges and resolutions and factory floor environments can be dirty, harsh, and unforgiving — making it difficult to differentiate between humans and other robots working in the same environment. TE Connectivity Sensor Solutions — Highlights Temperature Sensing Technology: Compact discrete negative temperature coefficient (NTC) thermistor sensors offer highly precise measurements and excellent long-term stability for monitoring the surface temperatures of industrial equipment. This NTC sensor technology uses the resistance properties of ceramic/ metal composites to measure the temperature. Additionally, digital temperature sensors are designed to be highly precise and provide robotic control and temperature optimization where space constraints exist. For high-temperature processes where temperature needs to be monitored at a distance, the integration of thermopile infrared (IR) sensors offer non-contact temperature measurement. Anisotropic Magnetoresistive Technology: With its anisotropic magnetoresistive technology (AMR) and multiple form factors, the KMXP position sensor provides excellent precision and reliable, accurate measurements in extreme environments including high temperatures. These sensors are playing an increasingly important role in many industrial robotic applications. Advanced applications in harsh environments need sensors that perform well, even when exposed to oil, dirt, and dust. These sensors are offered in two different DFN packages for multiple orientation options and the packages can be easily integrated into almost any automated assembly process.
