Belcom launches AS-i cabinet wiring cable
Belcom is adding a new product to its range of AS-i cables. In the harsh environments of industrial applications requiring IP6x levels of protection, AS-Interface is claimed to have established itself as the standard for automation technology. This is in large part due to its relatively low cost. Now, however, the actuator-sensor bus is becoming an attractive alternative for the relatively sheltered IP20 world as well.
The combined cable and interface system developed jointly by LEONI and Weidmller now makes it possible for users to profit from the AS-i advantages, not only outside but also inside the switching cabinet; it is claimed to provide a saving of 75 per cent over conventional installation times and a reduction of around 40 per cent over the usual cabling costs.
Like its IP6x counterpart, the new LEONI profile cable for switching cabinets transmits data and power simultaneously over two wires in the same cable. The present version designed for IP20 environments also offers new features. The outer jacket, for instance, is made of flame-retarding non-corrosive plastic (FRNC), is halogen-free and protected against reverse voltage. A specially designed nose and nosepiece provide for easy installation as well as for protection against possible damage to the strands when inserted incorrectly.
Easy, reliable connections
The appropriate interfacing system for the LEONI IP20 profile cable was developed by Weidmller, which is also a member of the AS International Association. With the help of some innovative simulation testing, Weidmller was able to optimise the contour of the new piercing contact in such a way that the insulation material can now be penetrated with ease. At the same time, however, the contact pressure of the wire onto the contour is maximised at the moment of contact, thereby reducing the likelihood of the wire becoming loose after the connection has been made.
With the new contact system, users will save time, money and space. Furthermore, retrofitting a switching cabinet with actuators and sensors no longer represents a problem.
