Secure fixings and metal backshells for Hi-Rel 1.25mm pitch connector family Gecko (G125 series) connectors are low-profile, dual row cable-to-board and board-to-board interconnects which save PCB real estate and weight in high reliability applications.

Overview

Gecko-SL contacts are rated to 2.8A individually, 2.0A for all contacts simultaneously. Able to withstand 1,000 mating cycles, they are ideal for long life or “fit and forget” applications, in operational temperatures of -65°C to +150°C. Gecko-SL connectors are rated to withstand 20g vibration and Z axis 100g 6m/s shock, with no discontinuity greater than 1µs, Z axis 100g. Gecko-SL connectors are manufactured from environmentally-friendly materials and are lead, phosphate and halogen free.

Shielding capabilities

Shielded options with machined aluminium backshells are available to deliver enhanced electrical continuity and effective EMI/RFI shielding in affected applications. The backshells are designed to accommodate flexible metal braiding and are strong and lightweight. Flexible cabling options include complete cable harnesses in customised lengths, loose mouldings and pre-crimped wires and loose mouldings and crimp contacts.

Features

  • 2A per contact (all electrically loaded; 2.8A per individual contact)
  • 4-finger Patented contact design to maintain electrical contact through high vibration and shock
