Additional Information

Additional Information

 N/A CeramTec coaxial connectors consist of two concentric conductors: a central conductor surrounded by and insulated from a second tubular conductor. The outside conductor is usually at ground potential but in some product variations may be floated off ground by employing an additional insulating ring. The outer conducting surface can prevent radio frequency noise from passing to or from the central conductor. CeramTec's Ceramaseal® product line includes a complete line of industry-standard coaxial connectors ranging from Microdot® through SHV. These coaxial connectors are manufactured for high and ultra-high vacuum service. These coaxial connectors are manufactured for high and ultra-high vacuum service.
