Contact free lateral double sheet control monitors a stack of blanks. The sensor AA90 is mounted laterally, and monitors the blank during the lifting process.

The loading process is interrupted only if more than one layer is recognized. Advantages upon tactile systems: no stop necessary, therefore no  time delay, contact free and wear-free. No time consuming mechanical adjustment necessary.

The sensor supplies a 4… 20 mA analog signal which may be evaluated by a PLC. Digital switching signals (0, 1, 2 sheet metal) can be produced with the control unit XA100, if an evaluation is not desired with the PLC.
