Why Choose the TE Connectivity 1SNA146072R2500 D2,5/5.N.ADO.Ex Terminal Block?

The TE Connectivity 1SNA146072R2500, also known as the D2,5/5.N.ADO.Ex, is a compact blue feed-through IDC terminal block designed for reliable conductor connections in industrial control panels, process automation systems and hazardous-area electrical installations. Part of the established ENTRELEC terminal block range, it combines ADO insulation displacement technology with a conventional screw clamp connection for efficient industrial wiring.

The D2,5/5.N.ADO.Ex provides two complementary termination technologies within a single terminal block. Its ADO insulation displacement connection enables fast conductor termination, while the screw clamp connection provides a secure and familiar termination method on the opposite side. The blue housing supports clear circuit identification, and the Ex-rated design makes the terminal suitable for appropriately engineered installations in potentially explosive atmospheres.

With a 1 mm² rated cross-section, 13.5 A rated current and 750 V rated voltage, the D2,5/5.N.ADO.Ex provides a space-efficient solution for industrial wiring. Its narrow 5 mm spacing supports high-density panel layouts, while compatibility with TH35-7.5 and TH35-15 DIN rails enables straightforward integration into standard electrical cabinets and automation systems.
