00 Series Circular Push Pull Connectors 00 Series Circular Push Pull Connectors were conceived for all applications in which a high density of connectors is necessary, especially for patch panels. The LEMO special self-latching system makes it possible to connect and disconnect with a simple axial push-pull, thereby reducing the space needed to mount sockets to an absolute minimum, up to 50 sockets per square decimeter. LEMO 00 Coaxial Connector series served as the norm for NIM-CAMAC CD/N549 standard, used in nuclear physics as well as many other applications.
