These connectors are hermaphroditic. Odd pin numbers on the module are connected to even pin numbers on the baseboard and vice versa.

4 x 5 modules use two or three Samtec Razor Beam LSHM connectors on the bottom side.

  • 2 x REF-189016-02 (compatible to LSHM-150-04.0-L-DV-A-S-K-TR), (100 pins, "50" per row)
  • 1 x REF-189017-02 (compatible to LSHM-130-04.0-L-DV-A-S-K-TR), (60 pins, "30" per row) (depending on module)

When using the same type on baseboard, the mating height is 8mm. Other mating heights are possible by using connectors with a different height:

The module can be manufactured using other connectors upon request.

The LSHM connector speed rating depends on the stacking height; please see the following table:
