VK1-40 (RK1-40), PKK1 and VK1-50 cable connectors are
used in combination with semirigid cables, RK1-18 (VK1-18),
RK1-20 (VK1-20), VK1U cable connectors — with flexible
cables, and RK1-20-16R (RK1U-20-16R) — with manually
shaped cables. Central conductors are made of tempered
beryllium bronze and plated with wear-proof gold. The
bodies of VK1-40 (RK1-40), RK1-18 (VK1-18), RK1-20 (VK1-20)
cable connectors are made of stainless steel. The bodies
of RK1-20-16R (RK1U-20-16R), VK1U, PKK1 and VK1-50 cable
connectors are made of tempered beryllium bronze and
plated with wear-proof gold. Materials and design of the
cable connectors provide low loss and reflection levels,
high stability of parameters for at least 5000 connect/
disconnect cycles for RK1-18 (VK1-18) connectors, 3000
connect/disconnect cycles for PKK1-20 (VK1-20) and VK1U
connectors, 2000 connect/disconnect cycles for VK1-40
(RK2-40) connectors, at least 500 connect/disconnect
cycles for RK1-20-16R (RK1У-20-16R), PKK1 connectors
and at least 300 connect/disconnect cycles for VK1-50
connectors.
