Why Choose the TE Connectivity D2.5/5.ADO Feed-Through Terminal Block?
The TE Connectivity 1SNA199558R0700 D2.5/5.ADO is a compact red 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, giving panel builders flexibility when terminating different conductor types.
The D2.5/5.ADO has a rated current of 13.5 A and a rated voltage of 1000 V. Its screw-clamp connection accommodates flexible conductors from 0.22–2.5 mm² and rigid conductors from 0.2–4 mm², while the ADO system is engineered for rapid conductor termination and can accommodate up to two wires per compatible ADO connection.
At only 5 mm wide, the terminal provides an efficient solution for high-density DIN rail installations. It mounts on standard TH35-7.5 and TH35-15 DIN rails, provides IP20 protection at the main terminals 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 simplify conductor termination while providing consistent electrical contact for industrial applications. Combining ADO technology with a conventional screw clamp allows the D2.5/5.ADO to support efficient installation while retaining the familiar screw connection method used throughout industrial control panels.
With a width of only 5 mm, the D2.5/5.ADO is particularly useful where DIN rail space is limited. Its 13.5 A current rating, 1000 V voltage rating and wide operating-temperature range make it a versatile choice for control, 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.
