Description

Overmoulded AT and DT Connectors – Reliable and Sealed Connectivity for Harsh Environments

Overmoulded AT and DT connectors provide strong and reliable electrical connections in harsh environments. They feature IP67/IP69K-rated sealing, which protects against water, dust, and contaminants. This makes them ideal for transportation, heavy-duty machinery, industrial automation, and agriculture.

 

The overmoulded design creates a seamless connection between the housing and cable. This prevents liquid ingress and improves mechanical durability. These connectors handle high vibration, impact, and extreme temperatures with ease.

 

Available in 2 to 12 positions, AT and DT connectors support various configurations. They come in male and female versions with options for double cable outlets, Y-distributors, and terminating caps. Additional features include protection circuits, LED indicators, and coding options to suit specific applications.

 

The AT series offers heavy-duty, multi-pin connectivity, while the DT series ensures secure latching and strong environmental seals. Both types use rugged thermoplastic housing, high-quality silicone seals, and durable copper-alloy contacts. These materials guarantee long-term electrical performance in demanding conditions.

 

Applications of Overmoulded AT and DT Connectors

These connectors are widely used in:

  • Agriculture and heavy machinery – Ensuring reliable connections in tractors, loaders, and excavators.

  • Industrial automation – Supporting automated equipment in manufacturing and processing plants.

  • Commercial and off-road vehicles – Used in trucks, buses, and construction vehicles for power and signal transmission.

  • Marine and outdoor equipment – Providing moisture-resistant connections for offshore and field applications.

 

 

Overmoulded AT and DT connectors deliver exceptional durability, environmental protection, and versatile installation options. Their rugged construction and high resistance to external factors make them the go-to choice for industrial, transportation, and heavy-duty applications. Whether for power distribution, signal transmission, or system integration, these connectors ensure long-lasting and stable electrical connections in the most demanding conditions.
