What is BS EN IEC 60512-23-3 - Shielding effectiveness of connectors about?
BS EN IEC 60512-23-3 is the 23rd part of an international standard that covers connectors for electrical and electronic equipment. This specifies the screening and filtering test method for measuring the shielding effectiveness of connectors which helps in manufacturing better quality connectors.
BS EN IEC 60512-23-3 defines a standard test method for measuring the shielding effectiveness SE of a shielded connector, or of a connector not provided with an integral shield once fitted with a shielding accessory and terminated with a screened cable. The complete assembly has a continuous 360° shielding capability throughout its length.
BS EN IEC 60512-23-3 gives a test method that can be applied to shielded connectors and to connector accessories with shielding capability. The connectors for electrical and electronic equipment covers:
- Circular connectors
- Rectangular connectors
- Connectors for printed boards
- Connector shielding accessories
Note: BS EN IEC 60512-23-3 has been adopted by ASD-STAN (formerly known as AECMA) as EN 2591-212.
Who is BS EN IEC 60512-23-3 - Shielding effectiveness of connectors for?
BS EN IEC 60512-23-3 on Connectors for electrical and electronic equipment is applicable to:
- Manufacturers of electronic devices
- Manufacturers of automotive parts
- Manufacturers of circuit boards
- Electronic engineers
Why should you use BS EN IEC 60512-23-3 - Shielding effectiveness of connectors?
Connectors are electromechanical components used for joining electronic conductors. These connectors are useful in creating electrical circuits.
The test method given in BS EN IEC 60512-23-3 utilizes the principle that the intrinsic shielding property of the connector/ accessory/cable assembly is its surface transfer impedance ZT which can be expressed as the longitudinal voltage inside the shield, relative to the current flow on the outside shell.
BS EN IEC 60512-23-3 specifies the test methods and test procedures for screening and filtering of these connectors. This test method is useful for the users in measuring the shielding effectiveness of a connector that is used in data bus systems. With the help of the test method, you can determine the longitudinal voltage inside the shield and the current flow outside the shell by using the intrinsic shielding property of the connector.
By using BS EN IEC 60512-23-3 you can activate the electromagnetic field which runs parallel to the surface of the specimen under test. By applying BS EN IEC 60512-23-3 you can manufacture good quality connectors that are used in electronic devices.
What’s changed since the last update?
BS EN IEC 60512-23-3:2019 supersedes BS EN 60512-23-3:2001, which is withdrawn. BS EN IEC 60512-23-3:2019 includes some technical changes with respect to the previous edition as:
- The frequency range for which this test method is considered reliable moved from 1 GHz to 3 GHz, to be consistent with Figure 7 (unchanged) and current industry practice and need
- Added a note to warn about the fact that this test method requires in 6.6 a TDR with a more stringent rise time of less than 100 ps than the value of less than 350 ps specified both in IEC 62153-4-6 and in EN 50289-1-6 for the similar line injection method applied to screened cables, whereas test 23g of IEC 60512-23-7 specifies for the same purpose a TDR with a rise time of less than 200 ps
- Symbols SE for shielding effectiveness and ZT for surface transfer impedance added throughout the document
- Adoption of term “connector housing” [IEV 581-27-10] instead of “shell” to address the connector accessory providing the shielding.
