AS-Interface shaped cable

■Overview

The actuator-sensor interface, the networking system for the low- est field level, is characterized by easy assembly and installa- tion. A new connection technique has been specially developed for the AS-Interface.

The network stations are interconnected via the the AS-Interface cable. This two-core cable has a trapezoidal profile which pre- vents polarity reversal.

Connection is made with the cable using the insulation penetra- tion technique. Blade contacts penetrate the AS-Interface shaped cable and make reliable contact with the two cores. Cutting and stripping of cores is not necessary. This technique allows AS-Interface stations (e.g. I/O modules, intelligent de- vices) to be connected in the shortest possible time. Devices can also be replaced in an instant.

The AS-Interface cable is offered in various materials (rubber, TPE, PUR) to suit applications in a wide range of environmental conditions (e.g. in an atmosphere saturated with oil particles).

It is also possible to use a round cable for special applications. In the case of AS-Interface, data and a 24 V DC auxiliary supply voltage can be connected for the sensors (e.g. BERO proximity switches) and actuators (e.g. LEDs) via the yellow AS-Interface cable.

For 24 V DC actuators (e.g. solenoid valves) that have a high current requirement or that are integrated into EMERGENCY STOP circuits, the black AS-Interface cable must be used.
