Space-saving screw-lock 1.25mm pitch connectors: smaller and lighter than Micro D

November 14, 2016 // By Julien Happich
The Gecko (G125 series) connectors released by Harwin are low-profile, dual row cable-to-board and board-to-board interconnects which save PCB real estate and weight in high reliability applications.

The new Gecko Screw-Lok Series features ruggedized 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.

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 to +150ºC. 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.
