Datasheet

There was an evolution of Harwin’s Gecko 1.25mm pitch connector series on show at the recent electronica exhibition in Munich. The 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. Developed to meet customer demand, the new Gecko Screw-Lok Series features ruggedised screw fixings for increased security and can withstand repeated mating cycles without damage.

Gecko-SL connectors feature Harwin’s patented single piece 4-finger beryllium copper female contact - the heart of the whole Gecko product family – and withstand high vibration, shock and extremes of temperature ensuring optimum electrical performance and durability under harsh conditions.

Robust stainless steel fixing hardware provides corrosion resistance against salt spray and humidity. Gecko SL connectors have captive screws with Hex socket heads to prevent slipping during assembly and a ‘mate before lock’ feature for fast assembly and increased usability. Strain relief is ensured through board mount fixings. Further features include identification of the number one position for fast visual inspection. Gecko SL connectors are available in female and male vertical through-hole and surface-mount variants.

Gecko SL contacts are rated to 2.8A individually, 2.0A for all contacts simultaneously. Able to withstand 1,000 mating cycles, they are well suited 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.

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