An important characteristic of the AS?Interface technology is the use of an unshielded two-core cable for data transmission and distribution of auxiliary power to the sensors and actuators. The special AS?Interface power supply unit supports the AS?Interface transmission method. The mechanically coded and thus polarized AS?Interface cable is used for wiring. The AS?Interface Modules are connected to the AS­Interface cable with insulation piercing contacts.

The ASIsafe concept supports direct integration of safety-related components, such as EMERGENCY-STOP switches, protective door switches or safety light arrays, in the AS?Interface network.
