ERNI Offers Press-Fit Power Tap Connectors

ERNI announced that it now offers single-pole Power Taps with press-fit termination. Press-fit technology is the preferred means for mounting most backplane components.

ERNI has equipped some of its popular series of Power Tap connectors with a new press-fit zone (i.e. EN - or "eye-of-the-needle" - zone). By changing to the new press-fit zone, one achieves a more evenly distributed force progression during press in. That, in turn, lowers the strain on the board's press-fit through hole. ERNI also offers versions with solder pins.

The new Power Tap model type features a deep-drawn, formed thread. These connectors feature a resilient press-fit zone and come in 6-pin and 10-pin versions. Power can be supplied via screw-mount connectors, or via slip-on pluggable connectors with cable lugs or flat terminal sockets (e.g "faston").

All variants are available with different connection threads (M3, M4, 6-32 UNC and 8-32 UNC). By employing a new material, the developers succeeded in increasing the maximum current-carrying capacity for the 6-pin version (6 press-fit pins) from 30 to 40 A (at 20 °C) to match the rating for the 10-pin version. The maximum permissible operating current depends on the characteristics of the specific PCB and on the cable termination.

The 10-pin Power Taps with press-fit termination are also available with "faston" termination. All the new Power Taps - including the "faston" versions - comply with the RoHS requirements.
