Description / Abstract:
Foreword
(This Foreword is not a part of American National Standard for High Voltage Connectors for Nuclear Instruments, N42.4-1971.)
This standard was proposed by American National Standards Committee N42 on Nuclear Instrumentation and adopted by ANSI in order to provide for interchangeability of safe high voltage connectors in nuclear instrument applications. The connectors are of the “safe” type in that the pin and socket contacts are well and securely recessed in the connector housing so that hand or body contact of the unmated connector with rated voltage applied will not result in electrical shock. It will be noted that the connectors covered by this standard are essentially identical to the NIM (Nuclear Instrumental Module) standard high voltage connectors specified in AEC Report TID-20893.
Suggestions for improvement gained in the use of this standard will be welcomed. They should be sent to the Secretariat for N42, Institute of Electrical and Electronics Engineers, 345 East 47th Street, New York, N. Y. 10017.
The American National Standards Committee N42 on Radiation Instrumentation had the following personnel the time it approved this standard:
Scope
This standard is applicable to coaxial high voltage connectors on nuclear instruments for dc applications up to 5000 volts and ac applications up to 3500 volts rms at 60 Hz. The connectors may also be used at higher frequencies provided the operating voltage is appropriately reduced.
