Overview

Berg connectors have a 2.54 mm (=.100 inch) pitch, pins are square (0.64 mm x 0.64 mm = approx. 0.025 x 0.025 inch), and usually come as single or double row connectors.

Many types of Berg connectors exist. Some of the more familiar ones used in IBM PC compatibles are:

  • the 4-pin polarized Berg connectors used to connect 3.5-inch floppy disk drive units to the power supply unit, usually referred to as simply a "floppy power connector", but often also referred to as LP4. This connector has a 2.5 mm pitch (not 2.54)!!
  • the 2-pin Berg connectors used to connect the front panel lights, turbo switch, and reset button to the motherboard, and
  • the 2-pin Berg connectors used as jumpers for motherboard configuration.

    • Floppy Drive power connector

    The power connector on 3.5" floppy drive is 2.50mm pitch (distance from center to center of pins).

    The power cable from the ATX power supply consists of 20 AWG wire to a 4-pin female connector. The plastic connector housing is TE Connectivity / AMP 171822-4 with female metal contact pins are choice of TE Connectivity / AMP 170204-* or 170262-*, where * is 1 or 2 or 4.

    The male PCB connector on the 3.5" floppy drive is a polarized right-angle male header, which is a TE Connectivity / AMP 171826-4, the vertical model is AMP 171825-4.
