Why Choose the TE Connectivity DSE4/8.ADO Terminal Block?
The TE Connectivity / Entrelec DSE4/8.ADO, part number 1SNA299557R0200, is a grey feed-through ADO miniblock terminal designed for compact industrial wiring installations. It combines Entrelec ADO connection technology with a conventional screw-clamp connection, providing two termination methods within a single DIN rail terminal.
This DSE version is manufactured without the separating rib for installation at the extremity of a compatible terminal block assembly and incorporates two notches for 1–2.5 mm² ADO conductors. With an 8 mm pitch, it provides a rated cross-section of 2.5 mm², an IEC rated current of 24 A and an IEC rated voltage of 1000 V.
The screw-clamp side accepts rigid conductors from 0.2–4 mm² and flexible conductors from 0.22–4 mm², while the ADO connection accommodates 1–2.5 mm² conductors. Measuring approximately 42.3 × 8 × 28 mm and weighing 7 g, the DSE4/8.ADO is a compact solution for industrial automation, machinery and control-panel applications.
Key Advantages
- Combines ADO and screw-clamp termination in one compact terminal block.
- Special without-rib configuration for the extremity of compatible terminal assemblies.

Compact ADO and Screw-Clamp Connectivity
The DSE4/8.ADO combines the speed and compactness of Entrelec's ADO connection system with the familiarity and conductor flexibility of a conventional screw clamp. The ADO side accommodates 1–2.5 mm² conductors and supports up to two wires per ADO connection, while the screw-clamp side accepts conductors up to 4 mm².
Unlike the standard DS4/8.ADO, the DSE4/8.ADO is supplied without the separating rib and is intended for use at the extremity of a compatible terminal block assembly. Its 24 A IEC current rating, 1000 V IEC voltage rating and compact 8 mm width make it well suited to space-conscious industrial terminal installations.
Typical Applications
- Terminal block assembly extremities.
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine control and instrumentation wiring.
- High-density DIN rail terminal assemblies.
- Process-control equipment.
- Industrial power and signal distribution.
- OEM machinery and electrical panel construction.
