VHDM® L-Series Module Configuration

The VHDM L-Series backplane module comes in two lengths, 10 position or column and 25 column. The matching daughtercard configuration is in multiples of 5 signal "wafers" (2mm each), assembled into a 5 column daughtercard module. The modules can be combined with power modules and modules containing polarizing and guidance to achieve the desired pin count and mix of features.

VHDM L-Series 5 Column Daughtercard

Daughtercard Signal Module

The VHDM L-Series daughtercard connector is comprised of 5 column press-fit signal modules mounted on a stainless steel rear organizer also called a stiffener. The 5 column assembly is comprised of 5 wafers assembled into a front insulator.

Backplane Signal Module

Available in press fit 10 and 25 column configurations with open ends for end-to-end stacking. End stacking of the modules enables connector configurations of up to 24 inches (609,6mm) or longer

VHDM Power Module

VHDM Power Module

Press-fit power modules are UL rated for 10 Amps/ 250 Volts per power blade.

  • The VHDM 8-Row power module contains 3 blades. Current interruption applications are rated at 4 Amps / 80 Volts per power blade.

  • The VHDM 6-Row power module contains 2 blades. Current interruption applications are rated at 4 Amps / 80 Volts per power blade.

Guidance & Keying

Press-fit backplane modules are available in 10 and 25 column configurations with integrated guidance and keying posts. (See photo)

Other guidance and keying options include stand-alone guide modules (pictured), ESD guide modules, board mounted guide pins and anti-rotation guide modules.
