Harwin Gecko-SL Series

Harwin Gecko-SL series 1.25mm connectors

Harwin has introduced Gecko-SL series 1.25mm connectors with the ease and strength of Screw-Lok (SL) jackscrew fixings

Harwin Gecko-SL Series 1.25mm Connectors

The existing Gecko-SL range combines the miniature yet powerful 1.25mm pitch connector system with the ease and strength of Screw-Lok (SL) jackscrew fixings. These screw-loks are made from stainless steel to ensure a strong and secure connection.

The range is now expanded to include a full range of ready-to-use Cable Assemblies. Versions include: male and female single-ended; male-to-male,
male-to-female, female-to-male. Each double ended cable connects contact 1 to contact 1, contact 2 to contact 2, etc.

With a choice of pin counts and cable lengths, these readily-available cable assemblies provide a convenient and tested cable solution, without the a
dditional requirements for tooling, training and testing necessary with in-house construction.
