Micro D Combo Series | Ulti-Mate Connector

Combination Power/Coax/Micro Contacts

Expandable tooling allows Ulti-Mate to offer any combination of Micro, Coax, and Power contacts in any of our standard 2 row shells from size 5 to 65 positions. A Coax or a Power contact replaces 6 micro contacts. For example, a size 21 connector can have 2 power and 7 micro contacts. Coaxial contacts are for use with RG 178/U miniature cables.

Two Row Configuration

Micro signal (24 AWG), Power (16 AWG, 10 Amps), Coax (40 Ohms)

From shell size 5 to 65

Maximum up to 10 power contacts and 5 signal contacts

Three Row Configuration

20 signal / 4 power or coax

Contact Engaging and Separating Forces

6 oz. max per MIL-DTL-83513 (contact average is 3 oz.); Separation force is 5.0 oz. minimum.

Contact Mating and Unmating Forces per MIL-DTL-83513

Mate = 10 oz. X number of contacts maximum. Unmate = 10.5 oz. X number of contacts minimum.

Shock and Vibration

Vibration	No damage or interruption detected (one microsecond sensitivity) when subjected to Method 2005, Test Condition IV of MIL-STD-1344.
Shock	No damage or interruption detected (one microsecond sensitivity) when subjected to Test Condition E. Method 2004 of MIL-STD-1344.
Durability	No mechanical defects after 500 matings; Test criteria are mating force, contact resistance, contact engagement, and separation forces.
Salt Spray	No exposure of base metal due to corrosion; no loss of performance as in durability above.
