Pressfit technology ensures high reliability for automotive electrical systems

November 25, 2013 // By Christoph Hammerschmidt
Backplanes and connectors manufacturer ERNI Electronics has introduced a new product line of automotive central electrical systems. Utilizing the pressfit technology, the BLUEcontact devices set new standards in terms of shock and vibration resistance and ensure reliable, compact connections with high current load capacity, the vendor claims.

The BLUEcontact line integrates the advantages of the pressfit technology, particularly in the commercial vehicle sector, where a reliable connection with the simultaneous use of high currents is particularly important.

Typical applications range from ABS to control and display units, alternators through to the supply of radio systems and accessories. The modules are characterised by their low power dissipation and high robustness against thermal and mechanical stress.

The compact central electrical systems of the BLUEcontact series currently comprise the following modules: Standard module with 16 ATO fuse sockets; standard module with 11 ATO fuse socket, a mini fuse socket and a mini relay socket; standard module with 9 ATO fuse sockets and two mini relay sockets in addition to a standard module with two maxi fuse sockets and two maxi relay sockets. All the modules are specified for the temperature range from -40 °C to + 85 °C. The power is supplied via power element sockets with supply currents of up to 100 A. The fuse sockets are designed for standard ATO fuses. The modules are suitable for 12 and 24V applications. As an option, the modules can also be supplied already equipped (relays, fuses and/or miniature circuit-breakers, free-wheeling diodes). The dimensions of the modules are 102 mm x 60 mm x 36.8 mm (44.6 mm).
