Piston contact array, 10 positions
The 821-22-010-10-004101 is the 10-contact member of Mill-Max's 821 series spring-loaded piston connector line, a single-row through-hole design. Contacts are copper alloy with 20.0µin (0.51µm) gold finish, and the 0.100" (2.54 mm) pitch matches standard breadboard and prototyping grid spacing.
Position count and pitch fit
The 821 series offers single-row piston connectors at the same 0.100" (2.54 mm) pitch; the 10-position 821-22-010-10-004101 sits alongside other circuit counts in the family, so the board footprint and contact finish are shared across the series.
