The series is lightweight and sealed, available in standard or custom configuration and fit for PCB and panel connection.

Nicomatic’s modular interconnect series, OPTIMUS, is suitable for harsh-environment, weight and space-constrained aerospace applications. Fully sealed and offering EMI protection, its connectors are also resistant to high vibration and shock, making them suitable for further use for military vehicles, defence avionics and robotics.

OPTIMUS is a rectangular, modular connector series, available in standard and custom layouts, tailored for harsher environments. In line with the requirements of the EN4165 and Arinc 809 standards, OPTIMUS is according to AS/EN 9100 quality management standards. OPTIMUS connectors are fully intermateable and interchangeable with existing EN 4165 solutions.  

OPTIMUS interconnects save space, thanks to their slim fit and high density and are also stackable. PCB adapted, offering efficient PCB fixing, they can be connected directly at the board level.  Robust blind mating and realignment in rack and panel saves assembly and maintenance time as both contacts and modules are removable.

The OPTIMUS ready-to-plug module is a single component, encompassing several functions for performance in harsh environments. Sealing is achieved in a single operation to perform three main functions: the interfacial seal ensures complete sealing between mated modules and reduces arcing; the peripheral seal ensures sealing between the modules and its shell cavity; the rear grommet compresses around the wires and protects against the ingress of liquid.  OPTIMUS modules feature moulded thermoplastic clips to ensure contact retention and a module retention clip which enables the module to fit in any adapted cavity, either a standard OPTIMUS shell or directly in the application equipment structure itself.

The flexibility of OPTIMUS modules can be demonstrated with modules and contacts incorporating size 8 through to size 22 M39029 and EN3155 contacts. Shells are two and four cavity, available in either aluminium 6061 or composite. Adapted surface treatments to provide salt spray protection are either black nickel (96 hours spray protection) or olive green cadmium (500 hours).
