Molex NearStack 100-Ohm 203316, 206138, 207244, 207249 series

Enabling speed upgrades in space-constrained telecommunications and data center applications tuned for 100-Ohm impedance, NearStack 100-Ohm connectors and cable assemblies deliver a dense, low-profile, near-ASIC cabled solution for jumper-type and I/O BiPass connections up to 56Gbps PAM-4.

Features 

• Reduces insertion loss for high-speed data applications
  • The double-ground structure between differential pairs (DPs) and direct-to-contact weld termination removes the paddle card and improves electrical performance for 56Gbps PAM-4 applications
• Optimizes PCB real estate in space-constrained applications
  • With a 0.60mm pitch between contacts and 2.40mm pitch between DPs, the dense connector design fits from 30DPs to 50DPs per square inch to deliver high data rates in a small footprint for networking and Top-Of-Rack (TOR) applications tuned for 100Ohms
• Enables expansion of DP sizes with minimal tooling investment
  • Contact wafers are arranged in “bays” to enable simple expansion from 8DPs to 16DPs
• Delivers secure connectivity for dense installations
  • An integrated “dual hasp” system offers up to 25N of retention force while an available positive lock with a pull bale increases the unlatch force to approximately 50N
• Offers robust attachment to the PCB
  • Tin-plated, stainless steel solder nails are pin-in-paste processed to ensure the plug is reliably attached to the PCB
