At the heart of the TBC connector is the patented, floating twin-beam contact. Its design and copper alloy material provide the high normal force and high conductivity for a reliable electrical connection. The mating points of the beams are tightly controlled near the front of the contact and provide a nominal .116 [2.95] contact wipe on the .210 [5.33] pin length and .070 [1.78] wipe on the .164 [4.17] pin length. Closed entry design prevents contact stubbing, while low mating forces enhance the mating of high-pin-count connectors.

The contacts permit two levels of sequencing when mated with a pin connector having pins of two different lengths: .164 [4.17] and .210 [5.33]. The long .210 [5.33] pin allows make first/ break-last capability.

TBC connectors are fully intermateable with AMP-HDI pin connectors and can use the same hardware. When sequencing is not desired, use standard AMP-HDI pin headers. The connectors are further available with any combination of long and short pins for sequencing.

Each TBC connector includes two eight-way keying slots and two mounting holes. They are available with zero, one, or two guide holes and a choice of .120 [3.05] or .180 [4.57] solder tails.
