Erni D-sub power connectors

Erni has available a range of D-sub connectors with precision stamped high-current contacts to meet the needs of SMT, through-hole reflow and press fit applications.

Expensive screw-machine power contacts are no longer necessary to achieve high-current demands. The company's power and signal contacts are stamped for maximum reliability and lower installed cost.

Designed to be used by fully automatic assembly equipment, the SMT and THR power devices provide a solution over manually placed connectors.

In applications that predominately use press fit connectors, such as backplanes, the company also provides a press fit power D-sub for gas tight contact requirements.

The angled high-current 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 with two contacts for a 60 V power supply. In press fit configuration, the high-current contacts are specified for a maximum current carrying capacity of 30 A (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).

For fully automated assembly, the power D-subs are available in both an SMT-compatible tray and tape-on-reel packaging.
