Heavy Duty Industrial Multipole Connectors

WAIN heavy duty industrial multipole connectors are designed for applications where reliable power and signal connections are required in demanding environments. These connectors are used across a wide range of sectors including mechanical engineering, energy technology, automation and transportation engineering.

When it comes to applications, WAIN industrial multipole connectors are used in heavy machinery, wind energy, rail transportation, power systems, photovoltaic installations, automation systems, communications equipment and stage and theatre lighting.

Designed for rigorous environments

WAIN industrial multipole connectors are rated IP65, providing protection against dust and water ingress. They are designed for environments where connectors may be exposed to mechanical stress, vibration and repeated connection cycles.

Key construction elements include:

• Die-cast aluminium hoods and bases

• Copper alloy contacts with hard silver plating

• Stainless steel handles

• Contacts designed for up to 500 mating cycles

These features support durable, repeatable connections in industrial installations where consistency and reliability are required.

Installation methods and configurations

WAIN heavy duty multipole connectors are available in multiple installation formats to suit different system layouts and connection requirements.

Available installation methods include:

• Panel mount

• Bulkhead mount

• In-line connections

To assemble a complete connector, the system is made up of:

• A hood and base, or an in-line coupling hood

• A plug insert and socket insert

This modular construction allows connectors to be configured to suit mechanical layout, enclosure interfaces and cable routing requirements.

Connector selection breakdown

When specifying a WAIN industrial multipole connector, selection typically involves considering the following elements.

Installation method

The installation format is selected based on how the connector interfaces with equipment. This may include panel-mounted interfaces for fixed equipment connections, bulkhead-mounted interfaces for enclosure pass-throughs, or in-line connections for cable-to-cable interfaces.

Housing and environmental protection

Hoods and bases are manufactured from die-cast aluminium and designed to provide mechanical protection. With an IP65 rating, these connectors are suitable for installations where resistance to dust and water ingress is required.

Contacts and electrical performance

Contacts are manufactured from copper alloy and hard silver plated, supporting reliable electrical performance. The contact system is designed for up to 500 mating cycles, supporting repeated connection and disconnection.

Mechanical durability

Stainless steel handles are used to support secure mating and unmating, contributing to connector longevity in industrial environments where mechanical forces are present.

System compatibility

WAIN’s extensive product range is compatible with other leading industrial connector brands. This allows customers to cross-reference part numbers and integrate connectors into existing systems without redesigning interfaces.

Range breadth and adaptability

WAIN provides a broad range of industrial connectivity components including connector inserts and contacts, housings and hoods, cable glands, wire harnesses and cable assemblies, and bandoliered products.

WAIN connectors are designed to support applications ranging from PCB data connections through to large-scale equipment systems, with design considerations covering data transmission, sealing, resistance to chemical corrosion, vibration, pressure and temperature variation.
