Tru-Loc® Connector Expansion: New 4-Way Plug and Receptacle Deliver Enhanced Reliability

Compact, corrosion-resistant connectors designed for reliable performance in automotive, heavy equipment, and oil-cooled motor applications

Amphenol Industrial Operations has expanded its proven Tru-Loc® connector series with the addition of new 4-way configurations, strengthening its lineup of rugged interconnect solutions for demanding environments. The newly introduced plug and receptacle options feature a redesigned latch mechanism and reinforced sealing to ensure long-term reliability in harsh operating conditions.

Proven Tru-Loc® Connector Performance

The Tru-Loc® connector series is built on Amphenol’s exclusive RADSOK® contact technology, which delivers high current capacity, low mating force, and superior durability compared to conventional interconnects. Designed for use in environments with extreme vibration, high temperatures, and continuous exposure to oil, Tru-Loc® connectors are trusted by OEMs in automotive, heavy equipment, and oil-cooled motor applications.

Introducing the New 4-Way Options

The expansion of the Tru-Loc® connector line provides greater design flexibility for engineers and system integrators. Both the new plug and receptacle designs feature an enhanced latch for improved connector retention and a robust main joint seal that maintains IP67 protection when mated. These enhancements ensure secure, oil-resistant performance in demanding applications such as diesel engine valve covers, industrial sensor connections, and high-vibration system environments.

Key Features of the Tru-Loc® Connector Series

The expanded Tru-Loc® family retains the performance qualities that have made the series a leader in rugged environments. Key attributes include:

• RADSOK® contact technology for superior current handling and durability
• Operating temperature range of -40°C to +125°C or +150°C (depending on configuration)
• 13A current rating with insulation resistance up to 100 MΩ
• Resistance to harsh fluids including diesel fuel and motor oil
• Vibration rating up to 32 Grms for high-reliability performance
• Ingress protection to IP67 when mated

Supporting Automotive and Heavy Equipment Applications

OEMs across the automotive and heavy equipment sectors rely on the Tru-Loc® family for critical applications. These include oil-cooled motors, fuel injectors, in-line signal transitions, and high-vibration sensors. The addition of new 4-way designs further enhances system design options to meet evolving customer requirements in electrified and oil-cooled technologies.
