The B11B-XASK-1-A is an 11-position, single-row header from JST's XA series, designed for board-to-cable/wire connections. The header is fully shrouded on all four sides, which protects the male pins from accidental shorting and guides the mating receptacle into alignment. Rated at 3A per contact and 250V, this header suits signal-level power distribution and low-current sensor/actuator interfaces.
Termination and mounting options
The header supports both press-fit and solder termination through the same through-hole footprint. Press-fit is useful for solderless backplane assembly where rework or high-reliability connections are needed; solder provides a conventional permanent joint. Tin is adequate for moderate mating cycles in clean environments; for higher cycle counts or corrosive atmospheres, consider the gold-plated variants in the XA series. A board guide feature on the housing assists alignment during assembly, reducing the risk of pin damage when mating the connector pair.
