Why Choose the TE Connectivity D2.5/5.ADO Feed-Through Terminal Block?
The TE Connectivity 1SNA199560R0500 D2.5/5.ADO is a compact yellow feed-through terminal block designed for industrial control panels, automation equipment and machine wiring. Part of the established ENTRELEC SNA ADO range, it combines the rapid ADO connection system with a conventional screw-clamp connection, providing a versatile solution for professional DIN rail wiring.
The D2.5/5.ADO has a rated cross-section of 1 mm², a rated current of 13.5 A and a rated voltage of 1000 V. Its screw-clamp connection accepts flexible conductors from 0.22–2.5 mm² and rigid conductors from 0.2–4 mm², while the ADO System supports rapid, repeatable conductor termination.
With a terminal spacing of only 5 mm, the D2.5/5.ADO is well suited to high-density terminal assemblies where DIN rail space is valuable. It provides IP20 protection at the main terminals, mounts on standard TH35-7.5 and TH35-15 DIN rails and operates across a wide temperature range of -55 to +110 °C.

Compact ADO and Screw-Clamp Connectivity
The ENTRELEC ADO System is designed to provide fast and reliable conductor termination for industrial electrical installations. The D2.5/5.ADO combines this technology with a standard screw clamp, allowing panel builders to benefit from ADO termination while retaining a conventional screw connection within the same feed-through terminal.
Its 5 mm-wide format makes the terminal particularly useful for densely populated control cabinets. Together with its 13.5 A current rating, 1000 V voltage rating, IP20 main terminals and wide operating-temperature range, this compact construction provides a practical solution for automation, instrumentation and machine-building applications.
Typical Applications
- Industrial electrical control panels.
- Factory automation systems.
- Machine control cabinets.
- PLC input and output wiring.
- Instrumentation and process-control systems.
- Signal and control circuits.
- Switchgear and electrical distribution equipment.
- Compact DIN rail terminal assemblies.
