Leica Absolute Tracker AT402

The easiest to use 3D Absolute Tracker ever
Leica Absolute Tracker AT402 faster and easier than ever before  
The Leica Absolute Tracker AT402 is the most portable 3D Absolute Tracker for traditional inspection tasks or for fully guided measurement processes. It is able to be powered by its own internal battery and is able to work in the most demanding environment, yet maintains the highest level of precision and the largest ever work envelope. The AT402 features increased ruggedness and extended battery life.
The Leica Absolute Tracker AT402 has a unique “All in One” system design that incorporates such needed accessories as built in live video, level to gravity, environmental monitoring and even an integrated IR remote control. By utilizing the integrated WiFi access point functionality the sensor can be used completely wirelessly.
A new level of portability & durability
The complete measurement system weighs less than 15 kg (33 lbs.) including the case and in a minimum configuration it will fit into the overhead compartment of most commercial airliners. This is truly the world’s most portable CMM.

Ready for any environment
Utilizing a completely sealed design that is independently IP54 (IEC 60529) certified means this sensor can be installed in the most unforgiving environments. Spraying coolant, dust, weld splash, nothing is too harsh for this sensor. The Leica Absolute Tracker AT402 is the first laser tracker certified for outdoor use, even in the rain.
Predefined measurement modes adjust the tracker to different conditions at the click of a button.

Leica Geosystems introduced the world to PowerLock in 2009. This vision technology detects a reflector and automatically locks the laser beam onto it, even when the target is moving. The laser beam moves to the user, not the other way around. In the past operating a laser tracker was almost a “black art”. It took time and experience for an operator to learn how to efficiently use the sensor without breaking the beam. PowerLock changed this completely and makes the handling of a laser tracker much easier.

Cable-less operation
With two identical batteries - one in the sensor, one in the controller- the Leica Absolute Tracker AT402 can run for a work day. When power approaches a critical level, the batteries can be either replaced or hot swapped. The laser tracker continues running as if nothing had happened. With the built in WiFi connection the Leica Absolute Tracker AT402 becomes a completely wireless portable CMM free from any external data or power cable requirements. Optionally the Leica Absolute Tracker AT402 is ready for Power over Ethernet. With this technology, a regular LAN cable supplies the sensor with both data and power.

Ultra Large Volume Measurements
With endless telescope rotation the sensor can measure a full 360° horizon and a 290° vertical dome. Pair this with a typical radial volume of 320 meters and you have the worlds largest volume precision CMM.

Complete system integration
The Leica Absolute Tracker AT402 is ready for any measurement task that comes its way. All accessories such as remote control, environmental monitor or level sensor are already built in.

A perfect match:
The Leica Absolute Tracker AT402 and the Leica B-Probe create an ultra-portable entry-level probing system.
