Military connector systems reduce board area required

1 November 2006 Interconnection

Nicomatic's TRIAX family of connectors offer a 5 mm contact pitch for the CMM connector series 350 (CMM300). The first products are female contacts on TWINAX cable and male contacts on PCB (straight and 90° through a flexible circuit soldered on PCB). An innovative feature of these devices is that the contacts can be inserted in a 'low cost' connector body, offering substantial space savings. The contacts enable a reduction in cost, while reaching the same level of performance as more expensive designs. The TRIAX contacts can be mounted on a standard connector or inside an electronic system.

Main applications for the contacts are military and aerospace systems. The material and surface treatments are compatible with the high demands of these markets. Security of data transmission is ensured by the 1553 bus (MIL STD 1553), an aerospace standard for signal transmission. The cables also conform to MIL-C-17/176D.

Nicomatic recommends a 0,6 mm diameter hole in the PCB to ensure optimum manufacturability. The company has used its expertise in miniaturising connectors to achieve a small 4,5 mm footprint.

The TRIAX family offers the advantages of secured transmission and the ability to use up to 12 contacts in a single row connector. The connectors offer an operating temperature of -55 to 125°C and 500 insertion cycles.
