Lightweight and rugged, Pattern 105 connectors are available in either olive drab cadmium or zinc cobalt finishes as standard and alternative finishes including RoHS-compliant plating are offered. They are available in solder, crimp and audio variants and the range features retained coupling nuts and arctic-style couplings for use in harsh environments.

Pattern 105 connectors have a positive coupling, three-bayonet pin construction with audible mate and contact arrangements from 2 to 61 contacts. Alternate keyway polarisation and insert orientation is available to avoid cross-plugging and mis-mating. The connectors can be supplied with a wide range of cable accessories. They are available with solder or crimp terminations and grounding springs for EMC shielding.
