These safe high voltage connectors meet all requirements of the NIM Standard (Nuclear Instrumentation Module)
Specification ND 545 Amendment A. Both the pin and socket contacts are securely recessed inside the insulation
to prevent the danger of electrical shock when live unmated connectors are handled.

They are particularly recommended for impulse circuits of linear accelerators as well as in military,
nuclear and medical electronics.

These connectors are not intermateable with those of the BNC and BNC.HT series.
