A low-force helix (LFH-60) is a 60-pin
electrical connector (four rows of 15 pins) with signals for two

Analog or analogue may refer to:
Computing and electronics
* Analog signal, in which information is encoded in a continuous variable
** Analog device, an apparatus that operates on analog signals
*** Analog electronics, circuits which use analog ...
connectors. Each of the pins is twisted approximately 45 degrees between the tip and the plastic frame which holds the pins in place. Hence "helix" in the name.

Using the LFH interface requires a
graphics card with multi-monitor capabilities and an LFH port.
