CONNECTION SYSTEMS

Delphi Active Connection Systems (ACS)
Delphi Active Connection Systems (ACS) are designed to meet high
vibration and temperature resistance demands placed on
connectors used in modern engines. The active secondary lock,
active Connector Position Assurance (CPA), and housing seal
enable advanced high-performance in high-temperature and highvibration environments.
Delphi's first generation Active Connection Systems include highperformance two-, three-, four, and five-way serial systems. A
second-generation two-way system with an updated terminal and
housing is also now available for enhanced performance.
The Active Connection Systems enable connectors to meet more
stringent requirements for vibration and temperature resistance and
updated safety-feature demands for engines. No device
modifications are required to take advantage of the Delphi Active
Connection Systems—the new generation terminal and connector
housing fits the same mating parts as previous generations.
The advanced ACS design features:

Delphi Active Connection System
2-way Connector

Combined radial and compression seal to eliminate
vibration-related failures by stabilizing the position using
radial and vertical forces in the sealing area
Active Terminal System (ATS) that utilizes a Delphi-unique
S-spring element that moves with vibrations to enhance
high-vibration performance
Active secondary lock, based on a modified Delphi ATS 2.8
terminal incorporating a special locking shoulder that
prevents the terminal from being pulled out once it is
inserted and the secondary lock is closed
o This secondary lock also serves as the coding
system and protects the housing seal
CPA which remains fixed in its pre-position until the
connector is plugged in
o As the connector is plugged in, the mating part opens
the pre-position, which allows the CPA to be closed

Benefits

Delphi Active Terminal System (ATS) Terminal
with Special Locking Feature

Enhanced vibration performance due to new housing seal design
and use of ATS terminal
Active secondary lock
o Incorporates with the new locking shoulder to prevent the terminal from being pulled out once it is inserted
and the secondary lock is closed
Can only lock if the terminal is completely in the cavity
o Provides protection against losing of the housing seal
Active CPA helps ensure only correct connections are made by preventing closure until the connector is fully plugged
in, helping minimize connection errors and to prevent accidental closures during delivery to enhance quality
Different mechanical color/codings available
