Size/Weight advantages
With space and weight a consideration for many high-reliability applications, Gecko-MT delivers a signal pin spacing of 1.25mm, and compact power pins. This design means that these connectors achieve significant space and weight saving over alternative high-performance connectors such as Combi Micro-D.
The diagram highlights the size savings of a 1+8+1 Gecko-MT over a comparable Combi Micro-D.
