Tightening Reliably with Wireless Technology

Wireless Technology

No more tool cables to restrict operator movement or become entangled: Wireless technology improves ergonomics and productivity at hard-to-reach screw bolt positions and in assembly line production.

New transducerized cordless nutrunner for increased versatility

The new series of cordless nutrunners from Rexroth, with torque and angle measuring function; integrated control system and wireless interface, greatly increases versatility in the assembly process. Applications such as working inside a car, where there is hard-to-reach bolt positions are where this product really excels. At the same time the wireless technology also improves ergonomics in walk-with applications and increases productivity, since workers are not burdened by cables.

The intelligent cordless nutrunners combine wireless technology with the advantages of the proven ErgoSpin nutrunners from Rexroth for all safety-critical connection points of Category A according to VDI2862. Results are stored and can be output for documentation purposes. An integrated transmitter securely sends data to the receiving station such as a standard enduser WLAN access point. Control electronics buffer data in the nutrunner in the event of a temporary disconnect and forward it as soon as the network is available again. This ensures that all procedures are fully documented and provides for high traceability as well as playing a key role in process reliability.

Due to the state or the art electronics, the cordless nutrunner from Rexroth can easily be integrated into the existing infrastructure of a production environment. Fully integrated control and performance electronics eliminate the need for a series of components such as tool and communication cables that would otherwise be required. This simplifies the installation and reduces costs. A color display is provided for configuration and worker data directly on the nutrunners. The new cordless nutrunner, like its proven ErgoSpin counterpart, has an ergonomically optimized design for fatigue-free working. An integrated, high-intensity LED also allows the bolt location to be optimally lit, even in poor light conditions.

The series covers tightening applications up to 50 Nm. Power is supplied by long-life, high-performance lithium-ion batteries. The cordless screwdrivers are endurance-tested to 500,000 cycles by Rexroth under full-load conditions.
