LEMO High voltage connectors: For the high voltage connector requirement of the nuclear industry, LEMO has created a new range of products in the series 0S, 1S, 1Y, 3Y, 4B & 5B which are distinguished by their very favourable size to voltage relationship. All these connectors are fitted with LEMO self-latching system for easy operation in very limited space. All the plugs have a safety locking ring, which prevents accidental manual unmating while power is being transmitted. The inserts are made of PEEK as well as silicone thus allowing LEMO to develop connectors with test voltages of 12kV rms upto 52 kV rms. These connectors are available as single contact high voltage connectors for applications requiring working voltages in kV's.
