150 & 280 Series GT
Connection Systems
Connection Systems
Description
The GT terminal and connector system was developed with global
customer input at every design phase and has a small package
size suited to fit the shrinking space requirements of today’s
vehicles. The GT Connection System includes:
•Tangless terminals with stamped serrations
• Pump-handle primary locks with integrated Connector Position
Assurance (CPA)
• Secondary lock capabilities including Terminal Position
Assurance (TPA) and Primary Lock Reinforcement (PLR) with
positive connector seal retention or a Slide Lock Cover (SLC) for
unsealed systems
•Female terminals compatible with ISO or SAE blades
Typical Applications
The GT Connection System is suitable for in-line, device, header
or bulkhead applications. The number and orientation of cavities
can be configured to a customer’s specific application. In addition
to providing customized designs, Delphi offers the following:
•GT150 and 280 Series available in both sealed and unsealed
versions in cavity variations between 2-way and 16-way.
• GT Mixed Series combining both 150 and 280 series terminals
in the same connector. Typically, 280 series terminal cavities
are located in the outside corners of the connector. This series
is available as a 12-way and 16-way sealed and unsealed.
• GT 150 Female Sealed connectors available with 3.5 mm
centerline spacing and various indexing capabilities. The 3.5
mm centerline spacing (vs. standard 4.5 mm) enables mating to
existing devices like sensors.
•GT Lever Lock Series available in both sealed and unsealed
versions, providing connector mating forces of less than 50
newtons for up to 40 terminations per connector.

Performance Advantages
Delphi’s patented high center rib connector seals exceed sealing
requirements (e.g. USCAR) for harsh vehicle environments. The
seals also reduce connector-to-connector mating force. The GT
Connection System’s terminal-to-terminal mating force is the
lowest in its class. When combined with the high center rib seal,
it results in the ergonomic benchmark for connections. The GT
Connection System satisfies ISO and USCAR electrical,
mechanical and environmental performance criteria as well as
specific customer requirements.
Terminals can be gold plated upon request.
