ERVAC SHV - Technical data 32 Technical data SHV (Safe High Voltage) connectors provide more secure handling as center contacts are well recessed to prevent shock hazards in unmated condition. All inner contacts are fully captivated and will withstand axial forces of 100 N minimum. When mating a connector pair the outer conductor contact is made prior to the inner conductor contacts. SHV connectors are suitable for all high voltage applica- tions up to 5 kV DC or 3.5 kV rms. These connectors are typically used in nuclear instruments or test and measurement equipment. Voltages are valid for both, the mated and the unmated condition. Interface dimensions conformable to the standards: IEC 60498, NIM ND-545 / USA: MIL-STD-348A/314 ANSI N 24.4 min. max. min. max.
