ERNI Rolls Out Right-Angle SMT D-Sub with Power Contacts

3/1/2004 - ERNI has expanded its range of D-sub connectors to include a new modular design. A variety of changes have been implemented to improve functionality and processing technology. Thanks to the modular design, it is now possible to generate virtually any number of variants at minimum expense.

Besides the SMT and press-in versions introduced earlier, D-sub male and female multipoint connectors with high-current contacts are now available in the 7W2 configuration as well. Configuration possibilities include 5W5 and 9W4 versions or other alternatives. For the first time, the power contacts are punched parts using SMT technology. The surface is silver-plated. Signal contacts can be partially assembled at no additional charge.

The new D-sub power connectors are available in the standard mounting height (7.3 mm) in accordance with DIN 41652 and CECC 75301-802. The nominal current is specified at 25 A (at 20° C) for the high-current contacts and 5 A (at 20° C) for the signal contacts. Beyond that, the maximum temperature limits for the application and the circuit board´s technical data must be taken into account. The test voltage is rated at 1000 Veff, and creepage distances and clearances are specified at > 1 mm.

For fully automatic assembly, the new D-sub high-current connectors are delivered on SMT-compatible trays or in tape-on-reel packaging. A black insulator body facilitates simple camera recognition (reflection method) and a large pick-and-place surface enables easy and reliable pick-up with the vacuum pipette. The optimized location of the center-of-gravity in connection with the positioning pins holds the D-sub in position during the soldering process. The insulator is made of high-temperature-resistant thermoplastic and is suitable for soldering in all SMT soldering processes commonly in use. The new generation of D-sub connectors already features the lead-free surface that will be mandatory as of July 2006.

ERNI Elektroapparate GmbH, a German member company of the international ERNI Holding Group, was established in 1956 and is headquartered in Adelberg (near Göppingen). ERNI develops and manufactures a wide variety of connectors for backplane and printed circuit board applications. The system technology business unit develops and produces customer-specific printed circuit board systems and backplanes. ERNI is a globally active enterprise with branch offices in Europe, North America and Asia. ERNI products are also marketed via a network of representatives and leading distributors.
