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.","metaTitle":"SM04B-GHS-TB JST GH Header 1.25mm 4-Pin Right-Angle SMT","metaDescription":"JST GH series 4-position header, 1.25mm pitch, right-angle SMT, locking ramp, tin contacts, rated 1A 50V.
