The 6PCV-04-006 is a 4-position 1-row Tri-barrier Strip with tin-plated copper alloy contacts and thermoplastic housing. The 6-1437652-7 1-level black terminal block has printed circuit pin bottom terminations, zinc chromate-plated steel 6-32 screw and combo Phillips-slot screw head. The tri-barrier block help contain stray or frayed wire ends. This helps prevent electrical shorts-not only between positions on the same block, but also between other components immediately adjacent to the block. With today's high density PCB designs, this has become an increasingly important feature.
