Additional Details

The B4B-XH-AM(LF)(SN) connector has a contact pitch of 2.5mm. The housing material is typically made of nylon, providing good insulation and mechanical strength. The current rating is typically around 3A AC/DC, and the voltage rating is around 250V AC/DC. The connector is designed for through-hole mounting onto a printed circuit board. Mating connectors include XH series crimp style housings with compatible terminals. The shrouded header provides protection to the contacts and aids in proper alignment during mating.
