SPRING-LOADED
CONNECTORS
SERIES 821 & 823 • .100” GRID THROUGH-HOLE MOUNT •
SINGLE AND DOUBLE ROW STRIPS
• Modular contacts for use on .100” grid, available in five heights from .137” to .236”, supplied
in single and double row contact strips
• Precision-machined piston / base and gold-plated components assure up to 1,000,000
cycle life durability
• Pistons have a long stroke relative to the low profile of the assembly
• Low resistance, high current contacts are rated at 2 amps continuous, 3 amps peak
• High temperature thermoplastic insulators are suitable for surface mount processes
• Both 821 & 823 series contact strips are designed for manual placement into Ø .022±.003”
plated through-holes in the circuit board prior to hand, wave or reflow soldering
