Harwin Gecko SL A brand new evolution of the award-winning Gecko 1.25mm pitch connector series launches today at Electronica from Harwin, the leading hi-rel connector and SMT board hardware manufacturer. 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. Up to 45% smaller than Micro-D connectors and up to 75% lighter, Gecko SL delivers high reliability with a smaller footprint and increased flexibility for design engineers.

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 No 1 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 ideal for long life or “fit and forget” applications, in operational temperatures of -65degC to +150degC. 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 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.
