Our MSH/MPH series circular connectors are mainly used for marine applications and meet the requirements of marine specification AGB/T538c and the NFC 93422 environmental test standard. Their conical coupling interface and square threaded screw coupling enable MSH/MPH series to withstand high vibrations and shock. MSH/MPH connectors are also suitable for harsh-environment applications such as military ships, railways, mining and public works.The special cone design on the backshell for cable braid/armor retention makes them extremely resistant to pull-out or transverse forces (80 kg). The O-ring at the coupling interface and the pressure gland at the backshell to cable interface (associated with optional protective cable boot) provide high-performance sealing. Dismountable crimp contacts make them easy to wire.
