Why Choose the TE Connectivity D2.5/5.ADO 1SNA199557R2600 Black Terminal Block?
The TE Connectivity D2.5/5.ADO 1SNA199557R2600 is a black feed-through terminal block from the Entrelec SNA ADO range, designed for compact industrial control and signal wiring. It combines an ADO System connection with a screw-clamp connection, providing a practical hybrid termination solution within a single DIN rail terminal.
With a terminal width of only 5 mm, the D2.5/5.ADO supports high-density panel layouts while accommodating rigid conductors up to 4 mm² and flexible conductors up to 2.5 mm² on the screw-clamp connection. The single-level feed-through configuration provides two connection points for straightforward conductor routing through the terminal assembly.
The 1SNA199557R2600 is rated at 13.5 A and 1000 V, with an 8 kV impulse withstand voltage. Its black thermoplastic insulating body is rated UL 94 V-0, while IP20 protection at the main terminals and compatibility with TH35 DIN rails make it well suited to industrial automation, machinery and control-panel installations.
