ERNI Releases Power D-Sub Connectors for SMT, Through-Hole & Pressfit Applications
ERNI Electronics is offering a range of D-Sub connectors with precision stamped high-current contacts to meet the needs of SMT, Through-Hole Reflow (THR) and Press Fit applications. The company claims that expensive screw-machine power contacts are no longer necessary to achieve high-current demands. ERNI’s power and signal contacts are said to be efficiently stamped for maximum reliablility and lower installed cost.
Designed to be used by fully automatic assembly equipment, ERNI’s SMT and THR power D-Subs are said to provide an economic solution over traditionally more expensive manually placed connectors. In applications that predominately use press fit connectors, such as backplanes, ERNI also provides a press fit power D-Sub for gas tight contact requirements.
The angled high-current D-Sub connectors are available in 3W3, 3WK3 and 7W2 configurations, and can be fitted with a maximum of three power supply contacts. However, partial assembly is also possible, an example being Deutsche Telekom, which specified a 3W3 version with two contacts for a 60V power supply. In press fit configuration, the high-current contacts are specified for a maximum current carrying capacity of 30A (at 20°C). The male and female multipoint connectors are supplied with the corresponding pre-installed nut or an ‘anti-twist’ interlock bolt (both available in M3 or 4#40 UNC) The RoHS-compliant power connectors are available in the standard installation height (7.3 mm), according to DIN 41652 and CECC 75301-802. For applications with a cable termination, ERNI also offers a D-Sub Power housing kit and high-current contacts with a solder or crimp connection for 10, 20, 30 and 40A.
For fully automated assembly, ERNI’s power D-Subs are available in both an SMT-compatible tray and tape-on-reel packaging. To further simplify pick & place processing, each connector has a large intake surface for easy and reliable vacuum pick-up. Positioning pegs are located at the center of gravity to optimize connector placement during soldering. The SMT power and signal contacts utilize ‘solder traps’ to minimize the wicking effect of solder away from the pads and durable surface brackets absorb extreme mechanical forces from mating and unmating heavy cables. The tin-plated terminals are contrasted by black high temperature resistant thermoplastic for improved visual inspection.
Pricing starts at $3.50 for these new D-Sub connectors.
