ERNI introduces ERbic MAX CAN Switch

1/13/2003 - With the introduction of the ERbic® MAX CAN Switch, ERNI is extending its popular and established family of Bus Interface Connectors. The MAX designates the Metal version with AXial cable outlet. A special feature of this new bus interface connector is the robust diecast metal housing, making it ideal for applications in rough environments, where EMC requirements are strict. The axial cable outlet on the ERbic MAX CAN is positioned in the mating direction. This achieves a narrow, space-saving, slimline form, as is required in applications where two fieldbus interfaces need to be on top of each other. The print terminals with screw terminations allow for CAN bus cables with sizes from 0.14 mm2 (AGW34) up to 1.0 mm2 (AWG 18) with a cable diameter of maximum 8.0 mm.

The ERbic MAX CAN Switch includes an integrated external switch by means of which the termination can be switched on or off. When a CAN network is extended, the ERbic, in which termination is active, can simply be switched to the node version without termination. For purposes of error diagnostics at a particular bus device it is possible to terminate the bus, and to decouple the following device. This switch is recessed from the outline of the housing, protecting it against accidental operation.

The ERbic line from ERNI provides a universal range of interface connectors through which reliable, compact automation solutions can easily be implemented. Versions for common bus systems such as CAN-Bus, Safetybus and Profibus up to 12 Mbps are available.

ERNI Elektroapparate GmbH, a German member company of the international ERNI Holding Group, was established in1956. At Adelberg (near Göppingen) and in Chester, Virginia (USA), ERNI develops and produces a wide range of connectors for backplane and printed circuit board applications, which was even further expanded by the takeover of Maxconn. In the system technology sector, customer-specific printed circuit board systems and backplanes were developed, which are produced in backplane shops in Germany, USA and Korea. In the financial year 2001 ERNI achieved a turnover of more than Euro 150 million with more than 750 employees. ERNI is globally active and has its own branches in all important industrial regions. The products are also sold via a network of representatives and leading distributors such as Arrow and RS. Further information is available at
