1sna146046r2300 – d4/6,d2,n,ado,ex
TE Connectivity 1SNA146046R2300 D4/6.D2.N.ADO.EX is a blue 1.5 mm² double-level feed-through terminal block with 6 mm spacing and screw-clamp/ADO connection technology for compact industrial and hazardous-area wiring assemblies.
Why Choose the TE Connectivity 1SNA146046R2300 D4/6.D2.N.ADO.EX Double-Level Terminal Block?
The TE Connectivity 1SNA146046R2300, manufacturer designation D4/6.D2.N.ADO.EX, is a blue double-level feed-through IDC terminal block designed for high-density industrial wiring and appropriately engineered hazardous-area installations. Part of the established ENTRELEC terminal block range, it combines screw-clamp and ADO connection technology with a compact two-level configuration.
With a 1.5 mm² rated cross-section and only 6 mm spacing, the D4/6.D2.N.ADO.EX enables multiple conductor connections to be arranged vertically while conserving valuable DIN rail space. The blue housing distinguishes this N version from the corresponding standard D4/6.D2.ADO.EX variant and supports clear circuit identification within organised panel assemblies.
The terminal is designed for installation on TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715. Its polyamide insulation, broad -55 to +110 °C operating temperature range and Ex-certified product family make it a robust choice for industrial automation, instrumentation, process-control and hazardous-area terminal assemblies.

Reliable High-Density Wiring for Industrial and Ex Applications
Double-level terminal blocks increase wiring density by providing two connection levels within one DIN rail position. The D4/6.D2.N.ADO.EX combines this space-efficient architecture with screw-clamp and ADO termination technology, making it particularly useful where numerous signal or control connections must be accommodated within a limited enclosure footprint.
The product belongs to an Ex-certified terminal block family for use within appropriately designed hazardous-area equipment. Its durable polyamide insulation, wide operating temperature range and compatibility with standard 35 mm DIN rails support dependable integration into industrial control, instrumentation and process applications.
Typical Applications
- Hazardous-area electrical assemblies.
- Industrial control and automation panels.
- High-density signal and control wiring.
- Instrumentation and process-control systems.
- Industrial junction boxes.
- Machine-building electrical systems.
- Process and manufacturing plants.
- OEM electrical and control-panel assemblies.
