Innovators of HALOSENSOR® Through Skin Sensor Technology

ZB3 Technologies Ltd stands at the forefront of aerospace smart tooling technology. Since 2003, we’ve been revolutionizing the global aero structures market with our unique patented HALOSENSOR® technology. Our mission is to provide solutions that enhance all stages of the aero manufacturing and MRO processes.

Our Expertise

At ZB3 Technologies Ltd, we specialize in manual, semi-robotic, and robotic drill position sensors, as well as smart tooling solutions. We are proud to serve a prestigious list of clients that includes industry giants such as Airbus, Boeing, Bombardier, Embraer, Spirit AeroSystems, Dassault Aviation, BAE Systems, Lockheed Martin, Northrop Grumman, and many more.

Custom Solutions for Aerospace Challenges

While we offer a range of standard manual and robotic drill position targeting systems suitable for most airframe manufacturing requirements, our true expertise shines when developing custom solutions. When faced with repeated drill issues, repair access challenges, or the development of new airframe production processes, we step in to save you time and money with HALOSENSOR® technologies.

HALOSENSOR® Technology Unleashed

Our patented HALOSENSOR® technology is a groundbreaking solution born out of discussions with BAE Systems in 1999. It was designed to tackle the persistent problem of accurately locating blind pilot holes or features through skin in aircraft structure assembly. This technology boasts the capability to work through various materials, including aluminium, carbon composites, titanium, and non-ferrous materials. Special targets even enable the detection of certain grades of stainless steel.

HALOSENSOR® technology offers unmatched accuracy advantages over traditional back drilling or match drilling methods. It eliminates costly issues like pipped holes and oval holes that have long plagued the aerospace industry. Our system excels at locating datum hole positions for drill jigs and aligning virtual templates in robot vision systems. Moreover, it plays a pivotal role in repairing, maintaining, and overhauling aircraft by accurately locating every hole in skin replacements.


Our journey with HALOSENSOR® technology began with the invention of prototypes in 1999, followed by patent filings in 2002. Today, HALOSENSOR® technology is integral to the production of Airbus and Boeing aircraft, as well as many other renowned aerospace companies and organizations.
