Overview
ISO 17612:2004 - "Tractors and machinery for agriculture and forestry - Auxiliary‑power‑transmission connector for the operator station" defines the essential interface dimensions and electrical characteristics for a 12 V auxiliary power connector installed inside the enclosed operator station (cab) of agricultural tractors and machinery. The standard specifies a convenient, non-environmentally sealed power outlet (power strip socket and matching plug) intended to supply auxiliary devices without modifying the vehicle wiring harness. The device is limited to a nominal +12 V d.c. system and a maximum current capacity of 30 A per connector.
Key topics and technical requirements
- Voltage and current
- Nominal voltage: +12 V d.c. at Contacts A and C (with reference to Contact B).
- Maximum current: 30 A total per connector (sum of switched and unswitched currents). Not applicable to 6 V or 24 V systems.
- Contact layout and function
- Three contacts: A = unswitched +12 V, B = negative battery reference (ground), C = switched +12 V.
- Contact positions and mating geometry are defined by the standard’s figures; tolerances follow ISO 2768-1.
- Mechanical features
- Connector consists of a power strip socket (one or more sockets) and a matching power strip plug.
- Each socket includes a lid that is spring-loaded or has a detent, with symbols indicating contact positions and functions.
- Female contacts must be at least tin‑plated to ensure reliable mating.
- Electrical protection & grounding
- Circuit protection for Contacts A and C must be provided and sized in line with the 30 A limit.
- Contact B must have a dedicated path to a convenient frame ground/ battery ground termination.
Applications and who uses this standard
ISO 17612:2004 is used by:
- Tractor and agricultural machinery OEMs and designers specifying cab power outlets.
- Electrical and mechanical engineers integrating auxiliary power strips into operator stations.
- Accessory and aftermarket manufacturers producing monitors, controllers, communication devices or light-duty on-board equipment that plug into cab power outlets.
- Compliance officers and procurement teams ensuring components meet international connector interface and safety criteria.
Practical applications include powering cab monitors, light-duty controllers, remote devices and off‑the‑shelf electronic accessories without rewiring the machine.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
This International Standard specifies an electrical connector for the transmission of auxiliary power within the
operator station of enclosed agricultural machines. The specification thus established will allow manufacturers
to provide both individual and multiple outlets in the cab. Typical applications include monitors, light-duty
controllers, remote operating devices and miscellaneous off-the-shelf items. Only the application dimensions
and electrical characteristics are covered.
Other electrical transmission connectors for agricultural tractors and machinery are specified in ISO/TR 12369.
