Mill-Max (Oyster Bay, NY) offers high-density, 0.050" pitch through-hole and surface mount spring-loaded connectors (SLC) available in single and double-row strip packaging. Series 854-22-0XX-10-001101 and 855-22-0XX-10-001101 through-hole insulators feature molded standoffs. Tail diameters of .016" require minimal diameter plated holes for connector mounting, maximizing signal routing between pins. Series 854-22-0XX-30-001101 and 855-22-0XX-30-001101 surface mount spring connectors are low profile, standing less than .230" tall when engaged mid-stroke (.0275"). Each SMT spring pin features a base geometry of .030" round by .010" tall to maximize soldering surface area and promote solder joint fillet.
