APOS Optic

The production lines of modern industry are becoming increasingly intelligent. The degree of networking of the systems is rising rapidly – and with it the demands on process reliability. Automatically controlled conveyor systems along assembly lines must therefore be positioned with millimeter precision under all conditions.

VAHLE has developed an optical positioning system that meets this requirement at all times. Two cameras integrated in the reading head optically scan a DataMatrix code along the line and determine the absolute position without any reference movement. By simultaneously detecting up to six code fields, gaps of 40 millimeters can be reliably traversed. Integrated LED illumination ensures reliable detection even in demanding environments.

The code tape can be integrated into the support profile of the conveyor system by means of an aluminum rail or glued directly onto a continuous steel structure.

The APOS Optic is optimized for combination with the VAHLE vDRIVE drive control system and is also compatible with various conductor systems (vPOWER) from VAHLE. If required, the APOS Optic can be supplemented with additional components for data transmission (vCOM) and designed as a system solution.

In addition, a comprehensive diagnostic kit is available to optimally align the read heads and also ensures comprehensive diagnosis of the system in the event of a fault.
