Product details

The 0.156" (3.96mm) pitch sets the board footprint and the per-contact current ceiling — at the rated current the temperature rise stays within the UL94 V-0 glass-filled thermoplastic housing. The shrouded - 1 wall protects the male square pins from bending during mating, and the friction lock retains the mating housing under vibration or cable strain. All 9 positions are loaded with tin-plated copper alloy pins.

Termination and mounting for through-hole assembly

The board guide and keying slot assist alignment during automated or manual insertion.
