2-Position 1.20mm Pitch SMT Right-Angle Header
The BM02B-ACHLKS-GAN-ETF(LF)(SN): JST ACHL series 2-position header, 1.20mm pitch, surface-mount right-angle orientation. Gold-plated male blade contacts rated 2 A per circuit at 50 V. Shrouded 3-wall housing with detent lock for positive mating retention. UL94 V-0 thermoplastic insulation, black.
Gold-Plated Contacts and 2 A Current Ceiling
The 2 A current rating per circuit is the maximum continuous current at the rated temperature; derate above 85°C ambient per the JST derating curve.
Peer Comparison: Pitch and Current Trade-offs
Compared to the JST NSH series 2-position header (SM02B-NSHSS-TB) at 1.00mm pitch and 1 A rating, the ACHL header offers wider pitch (1.20mm) and double the current capacity (2 A vs 1 A), with a shrouded 3-wall vs 4-wall design. The JST PH series 2-position header (B2B-PH-SM4-TB) at 2.00mm pitch and 2 A rating provides a larger footprint but same current, with a 4-wall shroud and tin-plated contacts. The ACHL's gold plating gives it an edge in mating cycle life over the tin-plated PH series.
