New On-Vehicle Data Connector from Amphenol Improves Vehicle Diagnostics

AT circular connector series used in heavy duty applications

Technical Specifications

  • Meets J1939 specification
  • Can withstand more than 100 mating cycles
  • Operating temperature of -55°C to +125°C
  • RoHs compliant

Sidney, N.Y. August 2020 – Amphenol Industrial Operations, a global leader in interconnect systems, now offers industry-standard, on-vehicle data plug connectors that are designed for vehicle diagnostic and data communication.  The AT circular connector (ATC) series is designed to perform in the most demanding applications in heavy duty trucks and buses.

The new 3 and 5 pole standard electrical plugs are designed to improve the quantity and quality of options offered by the ATC series. While the 9 pole provides a J1939 solution of receptacle/contacts/accessories.  SAE J1939 is a specified type of controller area network (CAN) that defines the communication pathways for vehicle networks.  Through a series of microprocessors, a CAN interconnects every device and establishes a common link between each other.

This new connector gives reliable support on CAN systems and helps electrical devices to communicate with each other. Applications include GPS tracking and CAN data communications for diagnostics of vehicle engine speed, temperature, oil temperature and exhaust emissions.

The round receptacles feature simple jam nut mounting for quick assembly and a smaller flange that saves space on mating panels. The heavy-duty industrial connectors are environmentally sealed against moisture and contaminants.

The connectors feature a reverse bayonet coupling design that allows for quick mating and unmating. They can withstand more than 100 mating cycles.

The RoHs compliant connectors work with industry standard size 16 contacts and are made from high quality copper alloy.  Nickel and gold plating are available.

AT circular connectors have an operating temperature range of -55°C to +125°C.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
