1sna199089r2500 – 2.5 ado black

Why Choose the TE Connectivity D2.5/8.ADO Black Feed-Through Terminal Block?

The TE Connectivity D2.5/8.ADO Black (1SNA199089R2500) is a compact 2.5 mm² ADO feed-through terminal block designed for reliable conductor termination in industrial control, automation and electrical panel applications. Part of the established TE Connectivity ENTRELEC SNA ADO range, it combines insulation-displacement connection technology with a space-efficient DIN rail format.

The D2.5/8.ADO uses the ADO System on both connection sides, providing rapid conductor termination without conventional screw-clamp wiring. Its self-stripping connection principle is particularly useful for repetitive panel assembly, helping simplify wiring while providing dependable connections in industrial equipment.

With a rated cross-section of 2.5 mm², rated current of 24 A and rated voltage of 1000 V, the 1SNA199089R2500 provides robust electrical performance in an 8 mm-wide terminal. Its black polyamide housing provides a useful colour-identification option, while compatibility with standard 35 mm DIN rails enables straightforward integration into terminal assemblies.
