Why Choose the TE Connectivity 1SNA199244R0400 D4/6.D2.N.ADO Terminal Block?
The TE Connectivity 1SNA199244R0400, also known as the D4/6.D2.N.ADO, is a compact blue double-deck feed-through DIN rail terminal block from the Entrelec SNA ADO range. Designed for high-density industrial control and automation wiring, it provides two independent feed-through circuits within a single 6 mm wide terminal footprint, helping reduce the amount of DIN rail space required inside electrical panels.
The D4/6.D2.N.ADO combines the ADO insulation displacement connection system with standard screw-clamp termination, providing installers with the benefits of fast ADO wiring alongside a conventional screw connection. The ADO connection can accommodate up to two wires per connection, making the terminal particularly useful for compact and flexible control-panel wiring.
With an IEC rated current of 17.5 A, an IEC rated voltage of 800 V and a rated conductor cross-section of 1.5 mm², the 1SNA199244R0400 is suitable for control, signal and distribution circuits in industrial equipment. Its two-level construction, IP20 main-terminal protection and compatibility with standard TH35 DIN rails make it a practical solution for densely populated electrical cabinets.

Space-Saving Connections for Industrial Control Panels
Double-deck terminal blocks provide two wiring levels within approximately the same DIN rail footprint as a conventional single-level terminal, allowing panel builders to increase connection density without unnecessarily increasing cabinet size. The two feed-through circuits of the D4/6.D2.N.ADO are independent, making the terminal suitable for organising separate control or signal circuits in high-density installations.
The combination of ADO insulation displacement technology and screw-clamp termination provides additional wiring flexibility. ADO technology enables rapid conductor termination and can accommodate up to two wires per connection, while the standard screw-clamp interface provides a familiar connection method for panel builders, machine manufacturers and maintenance engineers.
Typical Applications
- High-density industrial electrical control panels.
- PLC and automation system wiring.
- Machine building and OEM equipment.
- Process control and instrumentation cabinets.
