Connectors Offer 0.05 Inch PitchMill-Max has developed high density, 0.05 in. pitch through-hole and surface mount spring-loaded connectors (SLC) available in single and double-row strip packaging.

Each precision-machined spring pin component is plated 20 µ in. hard gold and assembled in a high temperature, thermoplastic insulator suitable for wave and reflow soldering processes. Every Mill-Max SLC is RoHS compliant.

Series 854-22-0XX-10-001101 and 855-22-0XX-10-001101 through-hole insulators feature molded standoffs to improve soldering and cleaning beneath the connector. Tail diameters of 0.016 in. 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 0.23 in. tall when engaged mid-stroke (0.0275 in.). Each SMT spring pin features a base geometry of 0.03 in. round by 0.01 in. tall to maximize soldering surface area and promote solder joint fillet.

Mill-Max also offers through-hole (Series 856-10-0XX-10-051000 and 857-10-0XX-10-051000) and surface mount (Series 856-10-0XX-30-051000 and 857-10-0XX-30-051000) 0.05 in. pitch Target Connectors. These provide a gold-plated, flat, and conductive mating surface for the 854/855 series. Series 856/857 are precision-machined and assembled into thermoplastic insulators. They are RoHS compliant and suitable for reflow soldering.
