The B04B-PASK-1(LF)(SN) is a 4-position 2.0mm pitch through-hole top-entry shrouded header from JST’s PA connector series. The PA series features a secure locking device that prevents accidental disconnection due to vibration or cable routing, along with an insertion guide mechanism for easy mating. The 3A current rating and 250V voltage rating make this connector suitable for power delivery and signal applications requiring higher current capacity than the PH series. The through-hole mounting provides superior mechanical strength compared to SMT alternatives, making it ideal for applications with heavy cable loads or frequent mating cycles.

The B04B-PASK-1(LF)(SN) operates as part of the PA disconnectable crimp-style connector system. The header is soldered through-hole to the PCB, providing strong mechanical anchoring. The PA series features a locking ramp device that engages with the mating housing to prevent accidental disconnection. The insertion guide on the header aligns the housing during mating, while the polarizing boss ensures correct orientation on the PCB. The 3A rating is achieved with phosphor bronze contacts and a contact design that provides sufficient normal force for reliable current carrying. The withstanding voltage of 1000V AC/minute provides excellent insulation for the 250V working voltage rating.
