1sna146045r2200 – d4/6,d2,ado,ex
TE Connectivity 1SNA146045R2200 D4/6.D2.ADO.EX is a 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 1SNA146045R2200 D4/6.D2.ADO.EX Double-Level Terminal Block?
The TE Connectivity 1SNA146045R2200, manufacturer designation D4/6.D2.ADO.EX, is a compact double-level feed-through terminal block designed for high-density industrial wiring and hazardous-area electrical installations. Part of the established ENTRELEC terminal block system, it combines screw-clamp and ADO connection technology in a two-level configuration that helps maximise connection density within control panels.
The D4/6.D2.ADO.EX features a 1.5 mm² rated cross-section and a narrow 6 mm spacing. Its two-level construction allows multiple circuits to be arranged vertically, reducing the DIN rail length required for complex control, instrumentation and automation wiring.
Designed as an Ex terminal block, the 1SNA146045R2200 belongs to the D4/6 ADO.Ex family covered by hazardous-area certification. Its light-grey polyamide housing, industrial connection system and compatibility with TH35 DIN rails make it suitable for professional electrical assemblies where reliable connections and efficient use of panel space are essential.

Reliable High-Density Wiring for Industrial and Ex Applications
Double-level terminal blocks allow two wiring levels to occupy a single DIN rail position, making them particularly useful where large numbers of circuits must be accommodated within limited enclosure space. The D4/6.D2.ADO.EX combines this space-efficient architecture with established screw-clamp and ADO termination technology for dependable industrial connections.
The Ex configuration makes this terminal block suitable for appropriately engineered hazardous-area assemblies, while its polyamide insulation and broad operating temperature range support demanding industrial environments. Mounting compatibility with both TH35-7.5 and TH35-15 rails simplifies integration into standard control-panel and junction-box designs.
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 plants and manufacturing equipment.
- OEM electrical and control-panel assemblies.
