Key features and benefits


838 series

The 838 connector series is used for electrical connections in harsh environment, with strong mechanical and climatic constraints. The 838 connectors are designed with aluminium alloy shell to enable a good compromise weight versus robustness. The screw locking system withstands very strong mechanical loads. A removable coding system allows the operator to choose between 12 positions for the cabling.
