MMA

MMA combines many of the best features from popular product lines including ARINC 600's power, RF, fiber optic and Quadrax contacts, low mating forces and shrouded size 22 pins. Sealing capabilities are comparable to M83527 with shell seal, face seal, and grommet. Modular, removable inserts are effective for separating signal and power contacts while providing ease of installation and customization in the field. Choose our 360° EMI spring option if shielding effectiveness is a concern. Customer specific designs lead to endless possibilities.

FEATURES AND BENEFITS

  • Blind Mate Low Mating Force Modular Connector
  • 40 Arrangements (size 22 contacts)
  • Size 22 pin contacts protected from damage by being shrouded by the insert face
  • Composite shells and Backshells available
