EKINOX 2 Surface Series 

– Hardware Manual  

EKINOX2HM.1.1

4. Electrical specifications

4.1. Overview

The Ekinox 2 connectors are all placed on the front panel. The connectors are referenced and identified by
laser marking on the enclosure. Each connector is different and fool proofed using a specific keying to avoid
any misconnection.

SBG Systems has selected high quality connectors designed for harsh environments. They offer an IP-68
protection when the plug is properly mounted.

4.1.1. Ekinox2-A and E with external aiding only

Ekinox2-A and E share the same form factor. 

4.1.2. Ekinox 2 N and D with dual antenna GNSS

Ekinox2-N and D share the same form factor. 

On the N model, only the ANT 1 connector will be used for GNSS position tracking.
