PQ50W Series, High Voltage, IP65 Waterproof Power Supply Connector

Hirose has introduced the PQ50W series to meet the requirement for IP65 water-resistant, high voltage connectors for harsh environments.

The connector range consists of cable plugs and panel mount receptacles.

The panel mount receptacle is user-friendly and can be easily assembled. This is achieved by unlocking the housing lock to detach the outer connector shell from the inner housing to allow easy termination of the contacts into the rear of the housing. The receptacle can be mounted on the front side of the panel. The crimp contacts utilised by the receptacle have a protective wall that prevents deformation of the contact and contact snare. The internal structure of the female crimp contact features 2-point contacts to guarantee contact reliability.

The plug utilises crimp contacts that have a protective wall that prevents deformation of the contact and contact snare. In addition, contacts of a different length can be installed for sequential mating.

The male and female inner housing blocks can be interchanged into the plug or receptacle shell allowing design flexibility.

PQ50W is IP65 water-resistant in the mated condition. This is achieved by tightening the metal cable clamp over the gasket to seal the connector which also increases the clamp strength.

The secure lock structure features two lock levers that move simultaneously to prevent a lever being left unlocked and aid the smooth operation of the mating and unmating operation.

The grounding structure features an independent ground contact that connects to the cover shell. The direct physical connection provides secure grounding.

A coding key system is available that allows multiple key variations to prevent incorrect insertion.

Other PQ series are available such as PQ50, robust zinc die cast shell version. PQ50S, light weight plastic shell version and PQ-WT, IP67 aluminium die cast shell version.
