Why Choose the TE Connectivity D6/8.ADO Terminal Block?
The TE Connectivity D6/8.ADO is a compact feed-through ADO/Screw terminal block designed for reliable electrical connections in industrial control panels, automation systems and electrical enclosures. Identified by manufacturer part number 1SNA199042R2500, this grey terminal block combines an ADO System connection on one side with a conventional screw clamp on the other, allowing different wiring methods to be used within the same terminal.
As part of the TE Connectivity Entrelec SNA Series, the D6/8.ADO is designed to provide fast and dependable wiring while maintaining the flexibility of traditional screw termination. The ADO connection uses insulation displacement technology for efficient conductor termination, while the screw-clamp side provides a familiar connection method for field wiring.
The D6/8.ADO has an 8 mm terminal width, a 24 A rated current and IP20 protection. It accepts 1–2.5 mm² conductors on the ADO side and supports a wider conductor range on the screw-clamp side, making it suitable for a broad range of industrial control and automation applications.
