Rectangular MIL-Spec connectors

Amphenol’s HDB3 rectangular connectors from AvnetAmphenol’s HDB3 rectangular connectors from Avnet incorporate a higher density contact pattern and lower mated height than Amphenol’s standard low mating force rectangular connectors, making them ideal for military applications. They utilize the same durable and reliable B3 brush contact in a tighter .070” X .060” staggered grid pattern. Available as a daughterboard and motherboard connector for both HDB3 and HSB3, as well as in I/O connector and board stacking connector configurations for HDB3.

Nicomatic’s DMM connectorsNicomatic’s DMM connectors comply with MIL-DTL-83513G. They allow space-saving, electromagnetic and mechanical protection and have a 2 mm pitch. One-piece or two-piece backshells provide 360° shielding. They can be equipped with contacts for signal (LF), power (HP), and coax (HF). Available in board-to-board, board-to-wire, wire-to-wire, and panel mount configurations.
