Why Choose the TE Connectivity 1SNA199245R0500 D4/6.D2.ADO.1 Terminal Block?
The TE Connectivity 1SNA199245R0500, also known as the D4/6.D2.ADO.1, is a compact grey double-deck ADO and screw-clamp feed-through DIN rail terminal block from the Entrelec SNA ADO range. Designed for high-density industrial control and automation wiring, it provides two connection levels within a narrow 6 mm footprint, helping panel builders maximise available DIN rail space.
The D4/6.D2.ADO.1 combines the Entrelec ADO insulation displacement connection system with screw-clamp technology, providing a practical hybrid connection solution for industrial wiring. Its double-deck construction allows separate circuits to be organised vertically, while the two levels are not internally connected, giving designers flexibility when arranging control, signal and auxiliary circuits.
With a rated cross-section of 1.5 mm², an IEC rated current of 17.5 A and a rated voltage of 800 V, the 1SNA199245R0500 provides dependable electrical performance in demanding control-panel environments. Its IP20 main-terminal protection, polyamide insulation and compatibility with standard TH35 DIN rails make it well suited to industrial machinery and automation installations.

Space-Saving Connections for Industrial Control Panels
Double-deck terminal blocks provide two wiring levels within a single DIN rail position, allowing panel builders to increase connection density without unnecessarily increasing cabinet size. The D4/6.D2.ADO.1 uses two levels that are not internally connected, enabling separate circuits to be organised efficiently within the same compact terminal footprint.
The combination of ADO insulation displacement technology and screw-clamp termination provides additional flexibility when designing or maintaining industrial wiring systems. Together with its narrow 6 mm profile, high voltage rating and broad operating temperature range, the D4/6.D2.ADO.1 is well suited to densely populated automation, machine control and process-control cabinets.
Typical Applications
- High-density industrial electrical control panels.
- PLC and automation system wiring.
- Machine building and OEM equipment.
- Process control and instrumentation cabinets.
- Factory automation systems.
- Control, signal and auxiliary circuit connections.
- DIN rail installations requiring two wiring levels in a compact footprint.
