HIGH VOLTAGE SINGLE CONTACT CONNECTORS Y, S, E AND 05 SERIES

Precision modular connectors to suit your application Since its creation in Switzerland in 1946 the LEMO Group has been recognized as a global leader of circular Push-Pull connectors and connector solutions. Today LEMO and its affiliated companies, REDEL and COELVER, are active in more than 80 countries with the help of over 40 subsidiaries and distributors. Over 75000 connectors The modular design of the LEMO range provides over 75000 connectors from miniature ø 3 mm to ø 50 mm, capable of handling cable diameters up to 30 mm and for up to 114 contacts. This vast portfolio enables you to select...

LEMO high voltage connectors (single contact) LEMO’s High Voltage Y series connector have been designed in the 70’s for the CERN, European Organization for Nuclear Research, one of the largest and most respected centers for scientific research. All the series presented in this catalogue (S series, E series, Y series and 05 series) are Push-Pull connectors that offer reliable construction, made of high grade materials. The design of these product increases the creepage distance of the interconnection enabling to guarantee high voltage working conditions

Y series (HV single contact) This family of single contact connectors are high voltage connectors designed for operating voltages ranging from 5 to 50 kV DC. They offer a great deal of security. The long housing permits a mechanical mating long before the contacts are engaged, thus ensuring safe mating. Furthermore, the socket in the series 3Y can be provided with a microswitch to prevent power from being turned on before the plug is mated.

Requirements in the field of nuclear research have given LEMO the opportunity to design a new generation of high voltage unipole connector in this Y series. They are mainly characterized by their extremely favourable size/test voltage ratio. The use of insulating material such as PEEK and silicone rubber in a new design of insulators allows to propose connectors withstanding up to 52 kV DC in the 3Y series.
