Lightweight, rectangular modular connector is sealed for mil-rel use

Compliant to EN4164 for aerospace and defence applications in standard and custom configurations, the Optimus is a lightweight, rectangular modular connector by Nicomatic.

The modular interconnect series is optimised for PCB and panel connection in harsh environment, weight and space-constrained aerospace applications. The fully sealed connectors offer EMI protection and are resistant to high vibration and shock, reported Nicomatic, making them suitable for military vehicles, defence avionics and robotics.

The rectangular, modular connector series is available in full standard and full custom layouts, but standardised to address increasingly harsh environments. In addition to EN4165, the connectors meet Arinc 809 standards and AS/EN 9100 quality management standards. The Optimus connectors are fully intermateable and interchangeable with existing EN 4165 devices.

The slim fit and high density save space compared to circular connectors, said Nicomatic. They are also stackable to further save space. PCB adapted, offering efficient PCB fixing, they can be connected directly at the board level.  Robust blind mating and re-alignment in rack and panel saves assembly and maintenance time. Both contacts and modules are removable to further simplify maintenance.

The Optimus ready-to-plug module is a single component, which achieves industry-leading sealing in a single operation, said Nicomatic. The interfacial seal ensures complete sealing between mated modules and reduces arcing, the peripheral seal ensures sealing between the modules and its shell cavity and 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.

Modules and contact options range from 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).
