BNC and SHV Feedthroughs
A range of feedthroughs including BNC and SHV feedthroughs is supplied by TSL. The feedthroughs
are UHV compatible and supplied with atmosphere side connectors. The SHV (safety high voltage)
connectors include recessed female contacts to prevent cross mating with BNC components. TSL is
also pleased to quote for customer designed feedthroughs for non-standard requirements.
