Product details

The BERGSTIK® family covers a wide range of positions and plating options, but this specific 20-position, single-row, gold-plated variant has no direct cross-reference on file.

The housing material is UL 94 V-0 rated — the connector will not propagate flame in an enclosed equipment assembly.

Frequently asked questions

Is 77311-801-20LF shrouded or unshrouded?

Unshrouded. The square pins are exposed with no plastic shroud around them. The mating receptacle must provide its own alignment, or the board layout must ensure pin-to-pin registration during assembly.
