Right-angle SMT orientation for board-edge cable exit
The SM04B-GHS-TB is a 4-position header from JST's GH series, terminated in a surface-mount right-angle footprint. This is the same fastening system used across the GH series, so the mating half is a standard GH crimp housing.
Current, voltage, and temperature ceiling
The 4-position version sits between the 3-position SM03B-GHS-TB and the 6-position SM06B-GHS-TB in the same GH series, all sharing the same pitch, current rating, mounting style, and locking ramp. The choice comes down to how many circuits the harness needs.
