Why Choose the TE Connectivity 1SNA199040R0700 D4/6.ADO Feed-Through Terminal Block?
The TE Connectivity 1SNA199040R0700, type D4/6.ADO, is a green feed-through terminal block from the Entrelec SNA ADO range, designed for dependable connections in industrial control, automation and machinery wiring. Its compact construction combines the ADO System with screw-clamp termination, providing a practical interface for modular DIN rail electrical assemblies.
The D4/6.ADO has a rated cross-section of 1.5 mm², a rated current of 17.5 A and a rated voltage of 1000 V. The screw connection accommodates fine-stranded conductors without ferrules from 0.22–4 mm² and rigid conductors from 0.2–4 mm², providing flexibility for common control-panel conductor sizes.
With a width of only 6 mm, the 1SNA199040R0700 supports high-density terminal arrangements without compromising accessibility. Its green thermoplastic insulating body carries a UL 94 V-0 flammability classification and is specified for an operating temperature range from -55 to +110 °C, making it suitable for demanding industrial electrical environments.

Compact ADO Connectivity for Industrial Wiring
The D4/6.ADO combines the Entrelec ADO connection concept with screw-clamp termination to provide a compact feed-through connection for industrial wiring. The arrangement is particularly useful where ADO-based wiring must interface with conventional conductor termination while retaining the modular construction and accessibility expected from a DIN rail terminal system.
Its 6 mm-wide profile allows multiple terminals to be installed efficiently within control cabinets, while the 17.5 A and 1000 V ratings support a broad range of control and signal circuits. The green housing also provides a clear visual distinction from otherwise similar D4/6.ADO colour variants, helping installers organise and identify circuits within larger terminal rows.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine control wiring.
- Signal and auxiliary circuits.
- ADO and screw-clamp wiring interfaces.
- DIN rail terminal block assemblies.
- OEM machinery and industrial electrical equipment.
