Modular contacts set on .ꢀꢁꢀ" centers, supplied in double-row contact arrangements.
Pads
Precision-machined piston / base and gold-plated components assure a ꢂ,ꢀꢀꢀ minimum cycle life.
Pistons have a .ꢀꢃꢄꢁ" mid stroke (when fully mated to PC board with a ꢅꢀ gram/contact force.)
Low resistance, high current contacts are rated at ꢃ amps continuous ꢆ amps peak.
High temperature thermoplastic insulators are suitable for surface mount processes.
Contact strips are designed for manual placement into ø.ꢀꢃꢆ .ꢀꢀꢆ" Plated thru-holes in the circuit board.
ꢇecommended for board thicknesses of .ꢀꢅꢃ" or greater.
