031-8557-000

Application Field and Working Principle

031-8557-000 circular connector from the market recognized HR Connectors series, is designed to meet the harsh climate and environment that occurs in military, aerospace and other extreme harsh environment. This circular connector is a 3-pole cylindrical connector, is a male plug that is modulated in accordance with the specification of EN19327. Equipped with HR’s oval coupling system it affords superior performance, backed up with an impressive array of approvals, certs and tests that are done on the 031-8557-000 to ensure that its performance meets all customer standards and requirements.

The 031-8557-000 has a very wide range of application fields due to its robust construction, which allows it to be an excellent choice for reliable signal carries in extreme harsh environments. Suitable for use in in industrial automation, medical systems, and automobile, its 3-100Amp current-compensated range makes it the ideal choice for providing reliable signal transfers.

The 031-8557-000 circular connector’s working principle initiates with the connection of the male plug and the female receptacle, which form the part of the coupling system. During this connection process, the specific shape of the male plug and its contacts mate with those of the female receptacle and by this, they ensure a reliable and tight connection that guarantees a good signal transfer and also blocks the entry of any foreign bodies. With the coupling of the 031-8557-000 it ensures a proper connection by a bayonet system. When the plug of the 031-8557-000 is completely connected with the female receptacle, the bayonet system will be engaged and operated by a locking ring.

In addition to the robust construction and the bayonet lock system, the 031-8557-000 is also designed with an additional protective system that will provide increased shock protection to the signal carriers and increase the life time of the connector, namely the Test and Maintain function (T&M). This function works by monitoring the connection’s internal contact and, when any change occurred on the contact resistance, the corresponding contact would be clearly pointed out and it will have to be replaced in order to guarantee a reliable signal transfer.

The 031-8557-000 is also designed with a corrosion protective system that prevents the equipment from any oxidation, dust and other debris. The IP-68 protection system guarantees a dust tight connection that prevents the possibility of any dust entry. In addition, the combination of the impeccable high quality of the contact materials along with a proper injection moulding techniques result in a complete joint connection that is impervious to all sorts of aggressive environments, such as high humidity, ozone and extreme temperature, allowing it to be used in any sort of environment resulting in a reliable and secure connection.
