Product details

It uses a 1.25mm pitch, which keeps the PCB footprint compact while still allowing hand-soldering or rework.

Pitch, footprint, and stack height

The 1.25mm mating pitch sets the PCB land pattern spacing. The header's mated stack height is 7.3mm, which determines the clearance between boards when mated with the corresponding GH receptacle. The SMT leads are tin-plated on the post side, matching standard lead-free soldering profiles. Pick-and-place features and solder retention aids are built into the package for automated assembly.

Frequently asked questions

What is the pin pitch of BM13B-GHS-TBT?

The mating pitch is 0.049 inches, which is 1.25mm.

Does BM13B-GHS-TBT have a locking ramp?

Yes, the fastening type is a locking ramp, which provides a positive latch with the mating GH receptacle.

Is BM13B-GHS-TBT compatible with GHR series connectors?
