Tight when it rotates freely!

The era of the torque wrench is coming to an end. We present the first connector which is tight when it rotates freely.

We are revolutionising the market for connection technology with the new M12Nm round connector. At the SPS/IPC/DRIVES 2008 we presented the first connector in the world which, without using a tool, gives a signal when it is tight. The integrated torque control system ensures that the connection is sealed in accordance with the IP67 protection class.

The principal problem with connection technology used to be that during work it was not possible to say for certain whether a connector was really mounted to the prescribed torque without using a torque wrench, and consequently there was no assurance that the required pressure on the O-ring had been achieved. The result was a connection which was either too tight or not tight enough. As the O-ring can be ruined if the connector is over tightened, both scenarios mean connections which do not form perfect seals.

We identified this problem and developed the first M12x1 round connector, which gives a message when it is sufficiently tight. The special feature of the new M12Nm with defined torque is that it can be tightened by hand and the result is a perfect seal. The integrated torque control system ensures that even without a tool the connection is sealed in accordance with the IP67 protection class and can, therefore, also be used industrially. By using the M12Nm the safety level in your application is increased.

The M12Nm will be available from the second quarter of 2009 as three, four and five pin versions and as connector and coupling in straight and angled variants.
