Blind Mating Connector Products

This week’s product roundup highlights blind mating connector solutions from leading suppliers.

Advanced InterconnectionsAdvanced Interconnections’ B2B® SMT ConnectorsB2B® SMT Connectors with solder ball terminals allow users to reliably define stack heights between two PCBs and are designed for robust handling in long-life applications including telecom switches, servers, processors, medical equipment, and military, aerospace, and defense systems. The series has a heavy-duty, shrouded design that provides positive polarization to aid in blind mating applications, screw-machined terminals with multi-finger contacts for enhanced reliability over a minimum of 500 mating cycles, and a high I/O density with 400+ beryllium copper (BeCu) signal, ground, and power contacts per square inch on a 1.27mm pitch, a compact insulator, and low stack heights to conserve valuable PCB space. The series can handle 3A per pin, allowing more contacts to be assigned to data and signal transfer than power and ground, and has a guide box design that facilitates the alignment of male pins into female receptacles and protects them from damage during board mating. RoHS compliant models with Sn/Ag/Cu solder ball terminals are available, as are custom configurations.

PositronicPositronic’s GFSH Goldfish Series mixed-density rectangular power connectors’s GFSH Goldfish Series mixed-density rectangular power connectors are designed for industrial applications that require reliable blind mating in a small package. The series delivers excellent power density, hot plug capabilities, and safety agency recognitions including UL94 V-0, UL 49351, RoHS 5/6 (6/6/ on select parts), and accepts multiple contact sizes to facilitate the mixing of AC/DC inputs, signals, and DC distributed outputs in a single package. Features include free-cable and panel-mount body styles, single-piece, gold-colored nylon insulators with keyway polarization, four sizes (22, 20, 16, and 12) of fixed or removable gold-plated copper alloy contacts, press-in or metal clip contact retention mechanisms that deliver 27–45N of contact retention force, open- or closed-entry female contact designs, wire or PCB terminations, and an optional locking system. The series is rated for 20A, 500V working, 1,000–1,500V proof, 5GΩ insulator resistance, 1.6mΩ maximum initial contact resistance, operating temperatures spanning -55°C to 105°C, and 500 mating cycles.

TE ConnectivityTE Connectivity’s AMP 5mm Power Key Connectors’s AMP 5mm Power Key Connectors are designed to optimize contact seating, ensure proper mating, and release bubbled created by potting processes in applications including gas appliances, laundry machines, household appliances, HVAC systems, power supplies, fan modules, lighting, and industrial controls. Comprised of plug housings for wire and compact PCB header assemblies with a 20.7mm mated height and double-lock plates that serve as terminal position assistance (TPA) devices and provide audible mating confirmation, these UL recognized and CSA certified wire-to-board connectors have a 5mm pitch, are rated for 300VAC at up to 10A, accept wire sizes spanning 26–16AWG, and are available in 2-, 3-, 4-, and 6-position single-row and 4- and 6-position dual-row configurations. Color-coding and four types of physical keying mechanisms (one for each color) improve blind mating efficiency and help prevent mismating.
