With just two circuits, this connector is ideal for simple power delivery connections such as DC input, battery, and speaker output wiring. The PA series secure lock mechanism prevents accidental disconnection, which is especially important for power connectors subject to cable pull forces. The 3A current rating handles typical low-voltage power delivery requirements, while the 250V voltage rating provides ample margin for most applications.","working_principle":"The B02B-PASK-1(LF)(SN) operates as a 2-circuit power connector in the PA series family. The through-hole mounting provides the strongest mechanical attachment to the PCB, which is critical for power connectors that experience higher insertion\/extraction forces during cable management. The locking ramp on the header engages with the BAP-02V-1 housing to prevent disconnection. The contact design maintains normal force above the minimum required for 3A current carrying, with contact resistance of 10m\u03a9 maximum initially.","pin_description":"
