It carries 6 positions in 3 rows on a 6.35 mm pitch, with a locking ramp that keeps the mated connector pair from backing out under vibration. The insulation is natural polyamide (nylon) rated UL94 V-0, so it self-extinguishes inside equipment enclosures that require flame-rated components.
Pitch, rows, and board footprint
The 6.35 mm pitch and 0.250-inch row spacing are wide enough to route traces between the through-hole pads on a standard 2-layer board without necking down. The 0.215-inch (5.46 mm) solder tail length suits boards up to about 1.6 mm thick. Three rows of 2 positions each — the 6.35 mm pitch means the header occupies roughly 12.7 mm × 12.7 mm of board real estate.
This is a positive lock, not a friction fit, so it resists vibration better than an unlatching header. The header accepts male pin contacts (circular, phosphor bronze) that mate with the Universal MATE-N-LOK receptacle housings and crimp sockets. Tin-on-tin contact interface is rated for moderate cycle counts — budget 25 to 50 mates before contact resistance rises.
