Product details

0.40mm Pitch Mezzanine Receptacle for Tight Stack Heights

The BM20B(0.6)-24DS-0.4V(51): Gold-plated contacts with 2.00µin (0.051µm) thickness handle the mating cycles typical of a mezzanine interconnect in portable or modular equipment.

Solder Retention and Surface Mount Termination

Surface mount termination suits automated pick-and-place assembly. The Tape & Reel packaging feeds directly into a placement machine, with Cut Tape available for prototype runs.

The BM20B(0.6)-24DS-0.4V(53) variant is a direct functional equivalent if supply conditions favour that suffix.
