Premier Cable PCM-HD-0308 uses a differentiated single-ended locking architecture. The vehicle-side connection uses an AU1 automotive USB Type-C locking interface, while the opposite end retains a standard USB Type-C connection. Unlike dual-AU1 assemblies, this configuration does not require both devices to use dedicated automotive connectors. It secures the vibration-sensitive vehicle-side interface while maintaining flexible Type-C compatibility for displays, controllers, test equipment and other electronic devices.
Continuous vehicle vibration, harness movement and thermal cycling can place mechanical stress on the equipment-side interface. PCM-HD-0308 concentrates its AU1 locking structure at this critical connection point. The automotive housing, mechanical latch and CPA mechanism help ensure complete mating and reduce loosening compared with a conventional friction-retained USB-C connection. Hirose AU1 is compliant with USCAR-2 and USCAR-30 requirements for automotive vibration and heat resistance.
Installation Requirements
The two ends serve different purposes. The AU1 locking end must mate with a compatible automotive AU1 receptacle, with key code, orientation and CPA engagement verified. The standard USB Type-C end connects to the corresponding target device. Pin assignment, cable length, protocol, power requirements and shielding should also be confirmed during system design. Connector-platform capability alone does not guarantee identical performance for every finished cable configuration.
Manufacturing Process
Because the two ends use different mechanical structures, PCM-HD-0308 manufacturing requires more than basic Type-C continuity. AU1-side PCB termination, locking-component assembly, shield continuity and standard Type-C termination must all be controlled. High-speed differential pairs require controlled stripping, conductor geometry and shielding to minimize impedance discontinuities. Finished assemblies can be validated for pin mapping, continuity, shorts, shielding and high-speed performance according to project requirements.
Service Life
The single-ended locking architecture gives each end a different role. The AU1 side is intended primarily for long-term connection to an automotive head unit or controller, while the standard Type-C end provides easier access for testing, servicing or peripheral connection. Hirose specifies AU1 for -40°C to +105°C operation and 10 mating cycles, emphasizing fixed automotive module interconnection rather than frequent consumer-style mating.

Product Features
● Single-Ended AU1 Automotive Lock
An AU1 locking interface secures the critical vehicle-side connection with latch and CPA retention, while the opposite standard Type-C end maintains broader connectivity.
● 24-Pin USB Type-C Architecture
AU1 is based on Hirose's proven CX USB Type-C architecture with a 24-position, 0.5 mm pitch interface. The platform supports USB 3.1 up to 10Gbps as well as DisplayPort and HDMI.
● CPA Mating Assurance
The AU1-side CPA mechanism helps verify complete connector engagement, reducing the risk of partial mating, vibration-related loosening and incorrect assembly.
● Standard A-Key Coding
Standard and A-Key mechanical coding physically distinguishes interfaces and supports mating-error prevention in connector-dense automotive electronic systems.
Core Application Scenarios
Automotive Display Systems
Designed for high-speed interconnection between center displays, passenger entertainment screens, digital clusters, rear-seat displays and display controllers. The AU1 locking end secures the vehicle-side head unit or display controller, while the standard USB Type-C end connects compatible display devices. This architecture supports USB and DisplayPort-class transmission while helping reduce connector movement, accidental loosening, display interruption and unstable data links caused by vehicle vibration and harness stress.
Automotive R&D & HIL Testing
Ideal for automotive HIL benches, smart cockpit prototypes, ECU development platforms, infotainment validation and automotive electronics laboratories. The AU1 locking end provides a secure connection to the device under test, while the standard USB Type-C end connects test computers, data acquisition equipment, display validation platforms or diagnostic devices. This single-ended locking design keeps the DUT-side interface stable while allowing engineers to change test equipment, reconfigure systems and evaluate different USB, display and data communication setups efficiently.
Core Performance Advantages
Critical-Side Retention
Positive locking is placed where it matters most-the vibration-sensitive head-unit or controller side intended to remain connected during long-term vehicle operation.
Standard Type-C Flexibility
The standard Type-C end provides a flexible bridge between an automotive-specific AU1 interface and compatible test equipment, peripherals or development platforms.
Reduced Intermittent Disconnects
Latch and CPA retention help reduce micro-movement, partial mating and harness-induced contact changes that can interrupt high-speed USB or display links.
Development-to-OEM Integration
AU1 key code, Type-C configuration, cable length, pin assignment, shielding, labeling and validation can be defined around development and OEM program requirements.
