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.
