Molex PowerWize BMI connectors 221991 series

PowerWize BMI connectors incorporate Molex’s COEUR socket technology, transmitting high currentcarrying capacity through right-angle and vertical headers. Available in three sizes - 3.40mm (75.0A), 6.00mm (110.0A) and 8.00mm (185.0A) - the blind-mating design helps ensure proper connections in hard-to-reach and visually obscured spaces.

Features

• Allows the option for mating vertical headers to panel-mount receptacle when required
  • Vertical headers are available in 8.00mm connectors
• Allows the panel-mount receptacle +/- 2.00mm of radial float to mitigate tolerance stack-up issues
  • Self-aligning panel-mount receptacle flanges accepts either force-fit standoffs paired with bolts (used when the assembler only has access to one side of the panel) or shoulder screws paired with nuts (often used when the assembler has access to both sides of the panel)
• Helps ensure right-angle headers are properly oriented on printed circuit board or busbar
  • Mechanical keying with crush/locating pegs are on the headers
• Provides terminal backout assurance
  • Two (opposed) positive locks hold the TPA retainer securely to the blind-mate receptacle housing silo with six beams robustly holding the crimp contact inside the TPA retainer
• Helps to ensure low contact resistance, low voltage drop and minimal heat generation at the contact interface
  • PowerWize Interconnects have multiple contact beams for optimal current-carrying capacity
• Helps ensure the receptacle is installed in the proper orientation
  • There is mechanical keying with unique geometry at the front of the panel-mount receptacle and matching geometry on the panel cutout
• Offers options to attach pins to different substrates for design and manufacturing flexibility
  • Screw-mount pins are attached to both printed circuit boards and busbars; solder tail pins are attached to printed circuit boards
• Enable the inner wall of the header shrouds to align the connectors during mating in drawer-style applications with obscured connectors
  • Blind-mating guideposts facilitating trouble-free mating
• Helps prevent mismating between the receptacle and header
  • These connectors offer mechanical keying with unique geometry at the front of the panel-mount receptacle and matching geometry on the header shroud
• Provides design and manufacturing flexibility
  • Crimp contacts are available to accept a wide range of wire gauges (from 10AWG to 1/0 AWG)
• Achieves additional board retention (if desired)
  • Secondary substrate attachment includes the attachment of the right-angle header to the substrate using M3 bolts, nuts and the two mounting flanges molded into the body of the header
• Helps ensure minimal contact resistance at the interface between the wire and the crimp barrel
  • Reliable crimp geometry eight-sided crimp profile contributes to the system’s minimal heat generation and higher current-carrying capacity compared to other designs
