It mates with GH series crimp receptacles (e.g., GHR-05V-S) to form a wire-to-board connection. The shrouded 4-wall design and locking ramp secure the mating pair against vibration-induced disconnection. ## SMT assembly and retention Mated stacking height is 7.3mm, which sets the board-to-cable clearance in the final assembly. ## Position count vs. sibling The closest functional sibling is the BM06B-GHS-TBT, which shares the same pitch, current rating, voltage, locking ramp, and SMT features but carries 6 positions instead of 5. Both use the same GH series receptacle family — the difference is purely the circuit count on the board.","metaTitle":"BM05B-GHS-TBT JST GH Series 5-Pin 1.25mm Pitch SMT Header","metaDescription":"BM05B-GHS-TBT JST GH series 5-position SMT header, 1.25mm pitch, 1A, 50V, locking ramp, pick-and-place, solder retention, UL94 V-0.
