Introduction
ACT
The Deutsch ACT is a high performance composite connector qualified to MIL-DTL-38999. What Deutsch
Defense/Aerospace does better than anyone else is make wire termination devices for demanding applications.
Deutsch utilized its unprecedented achievements in the area of defense/aerospace composite technology enabling us to
design and produce the latest version of MIL-DTL-38999 connectors.
The superior design of the ACT deliberately took into consideration the connector, its contacts, and the respective strain
reliefs to favorably influence intra-system life-cycle performance and costs.
I
Performance
The total performance of the ACT connector is matched by individual components within the system. For example, the
use of composite materials has increased the durability of the connector housing and coupling mechanism to 1500 cycles.
Deutsch developed an extended life MIL-C-39029 contact to meet the increased performance requiremets of today’s sys-
tems.
I
Superior corrosion resistance
The ACT eliminates the largest contributing factor in advanced systems malfunction... corrosion, which is the main cause
of mechanical, electrical, and electromagnetic connector degradation. Electromotive force differentials between many
dissimilar metals found in connectors and accessories produce galvanic action. The ACT eliminates these dissimilar metals
resulting in an interconnection system that withstands over 2000 hours of salt spray.
