Low Force Helix
Encyclopedia
Low Force Helix is a 60-pin electrical connector
(4 rows of 15 pins) with signals for 2 digital
and analog
connectors.
The LFH connector is typically used with workstations, because it can connect a single computer
graphics source to up to four different monitors. The standard interface is a 60-pin LFH connector with two breakout VGA
or DVI
cables. This system provides users with flexibility for a variety of display configurations, though forsakes standard DVI or VGA connectors. This renders the LFH connector unuseable without an adapter.
Using the LFH interface requires a graphics card with multi-monitor capabilities and an LFH port. Currently, NVIDIA
and BFG Technologies
manufacture such cards.
Another application of LFH capabilities is manufactured by Matrox
. The Matrox card outputs via two LFH cables to a single monitor, delivering 9.2 million pixels of resolution (3840 x 2400). This system provides large amounts of detailed information for professional applications such as aerospace and automotive visualization, computer aided design, desktop publishing
, digital photography
, life sciences
, mapping
, oil and gas exploration, plant design and management, satellite imaging, space exploration
, and transportation and logistics
.
The LFH connector is present as a serial interface on Cisco
1000 series routers.
Electrical connector
An electrical connector is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly. The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or...
