Product details

2.50 mm pitch, 2-position header with locking ramp

The B02B-XASK-1N: This is a JST XA series 2-position male pin header on 2.50 mm pitch, designed for board-to-wire applications where a secure, vibration-resistant connection is needed.

Through-hole termination and press-fit option

Termination is listed as press-fit and solder — the through-hole posts (0.134" / 3.40 mm long) are tin-plated for solderability, while the press-fit feature allows a compliant-pin option in the same housing for solderless backplane assembly. The housing is natural (uncolored) glass-filled nylon 6/6, rated UL94 V-0 for flammability.

Frequently asked questions

What is the pitch of B02B-XASK-1N?
