Miniaturization in the Military
“Maintaining a lightweight design is extremely important when dealing with portable units. Some connectors provide a weight savings of up to 75% compared to standard connectors.”
-‐‑ Wim Vanheertum, Product Manager Fischer Connectors SA
Miniaturization in the Military
Considerations include making sure the miniature connector is not so small or difficult to use that soldiers can’t manage to connect or disconnect when wearing gloves.

Miniaturization in Medical Smaller, more portable devices, along with an increase in body-‐‑worn medical devices, drives demand for miniature and/or multi-‐‑functional connector solutions.
Miniaturization in Instrumentation
Sealing to IP68 is a challenge when it comes to miniature connectors, but it can be done, allowing even the most sensitive instruments to remain accurate in extreme conditions.

Miniaturization Challenges
• . Challenge Action
Miniature connectors aren’t rugged enough for application, or cannot be sealed to IP specifications
Keep looking. There are companies that specialize in rugged miniature connectors that can withstand extreme environments and/or frequent connects and disconnects.
Sourcing the right cable for a dense connector solution that is multi-‐‑functional.
Check with your connector partner to get cable recommendations. Look for an authorized assembly house to help.
Right-‐‑sizing: Sometimes a connector can be too small to be practical for its intended use.
Be sure to field test with gloves if necessary before commioing to a connector.
Integrating signal and data into a miniature connector may lead to electrical interference.
Make sure you are working with companies that understand shielding and how it works in miniature connectors.
Miniaturization of Connectors – Challenges
Skilled Assembly
Sourcing Miniature and Technical Cable
Miniaturization of Connectors – Design Considerations
Electrical Requirements • Current (conductor AWG) • Voltage (Creepage & Clearance) • Shielding
Material Requirements • Metal or Plastic • Non-‐‑magnetic • Environmental Resistance
Data Transfer Rates • Ethernet • USB • RF (coax) • Fiber Optic
Cable Configurations
When it comes to miniaturization, choose your cable wisely

Miniaturization of Connectors – EMI / EMC Impact
Less material = Less shielding • Multiple sleeves
Smaller = BeDer for RF • At higher frequencies
ODU AMC®- PROCTECTIVE CAPS AMC® caps provide water, sand, dust protection and EMI protection for equipment up to 60db. § For plugs Break-‐‑Away and Push-‐‑Pull § For receptacle G8 § For receptacle GK and in-‐‑line receptacle
Miniaturization of Connectors – True Costs

Machining tolerance Skilled Labor Assembly Time Custom Cable
Lower Your Total Cost of Ownership
A well-‐‑chosen miniature, dense connector can replace more than one standard connector, saving space on the device, investment in materials, and even make a beoer end user experience.
