The other Marking Unit is powered by means of compressed air. An electrical impulse signal activates a free positional solenoid valve. The applied compressed air is then passed onto the drive unit of the Marking Unit. The graving tool receives a combined rotating/stroke movement, is then pushed against the PC Board – and marks the PC Board with a permanent circle of 2 mm diameter. The compact design of the Marking Unit allows space-saving assembly in the test fixture. The separation of the drive unit and the Marking Unit itself minimizes the influence of electro-magnetic interference fields both on the PC Board as well as in regard to the measurement signal. The mounting of the Marking Unit can be carried out either with the outside thread MF 16 x 1, or on the shaft of the Unit with either the [ 12 mm or [ 4.5 mm section.
