This SAE Standard establishes the minimum construction and performance requirements for a 15 pole connector between towing vehicles and trailers, for trucks, trailers, and dollies, for 12 VDC nominal applications in conjunction with SAE J2742. The connector accommodates both power and ISO 11992-1 signal circuits along with dual ground wires to accommodate grounding requirements within the constraints of the SAE J2691 terminal capacity.
This SAE Standard encompasses connectors between two cables or between a cable and an electrical component and focuses on the connectors external to the electrical component. This document provides environmental test requirements and acceptance criteria for the application of connectors for direct current electrical systems of 60 V or less in the majority of heavy-duty applications typically used in off-highway machinery. Severe applications can require higher test levels or field-testing on the intended application.
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration that is functionally similar to MIL-STD-1553B with Notice 2 but with a star topology and some deleted functionality. Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences. These designer selected options must exist to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architectural redundancy, degradation concept, and traffic patterns peculiar to the specific application requirements.
AS5653 may be applied to Air Vehicles and Stores implementing MIL-STD-1760 Interface Standard for Aircraft/Store Electrical Interconnection System.
This document covers the dimensional definition of the SAE J3400 (NACS) electric vehicle coupler, which includes the connector and inlet.
Electric vehicle (EV) growth may be stagnant in certain market sectors amid pushback on EV mandates along with lingering infrastructure and TCO concerns, but in terminal tractor operations electrification is growing in demand. As part of its initial Run on Less - Electric demonstration, the North American Council for Freight Efficiency (NACFE) concluded that terminal tractors are “one of the best, if not the best, paths for heavy-duty tractor fleets to learn about and implement a BEV in a fleet operation.” Fleets operating in ports, intermodal yards and other logistics hubs have a new option from which to choose now that Kalmar officially began sales of its Ottawa T2 EV electric terminal tractor. The order book opened at the Technology & Maintenance Council's (TMC) 2025 Transportation Technology Exhibition in Nashville, Tennessee, in March. Kalmar states that select customers have already placed preorders. Initial deliveries will begin in Q2 2025.
