Why Choose the TE Connectivity 1SNA199061R2000 D2.5/8.N.ADO Terminal Block?
The TE Connectivity 1SNA199061R2000, also known as the D2.5/8.N.ADO or 2.5 N.ADO, is a blue 2.5 mm² ADO/ADO feed-through DIN rail terminal block from the Entrelec SNA ADO range. Designed for industrial control and electrical panel applications, it provides a fast and dependable connection for conductors using ADO insulation displacement connection technology.
The ADO connection system enables conductors to be terminated without conventional screw-clamp connections, helping reduce wiring time while providing a secure electrical connection. The technology is particularly suited to demanding control applications where resistance to vibration, shock and corrosion is important.
With an IEC rated current of 24 A, an IEC rated voltage of 1000 V and support for conductors up to 2.5 mm², the 1SNA199061R2000 provides a compact solution for industrial wiring. Its 8 mm width and compatibility with standard TH35 DIN rails make it suitable for organised, space-efficient control panel installations.

Reliable ADO Connections for Industrial Control Panels
ADO insulation displacement technology is designed to simplify conductor termination by creating the electrical connection directly through the conductor insulation. This reduces the need for conventional conductor preparation and screw tightening, helping improve wiring productivity while maintaining consistent connection quality.
The SNA ADO range is particularly suited to industrial control systems where secure connections are required under demanding operating conditions. The compact DIN rail format of the D2.5/8.N.ADO makes it suitable for densely populated control cabinets, machine panels and automation installations while its blue body provides clear visual identification within the terminal assembly.
Typical Applications
- Industrial electrical control panels.
- Machine building and OEM automation systems.
- PLC and control circuit wiring.
- Industrial distribution and interface cabinets.
- Factory automation equipment.
- DIN rail terminal assemblies requiring blue conductor identification.
