Why Choose the TE Connectivity 1SNA199069R0000 D4/6.ADO Red Feed-Through Terminal Block?
The TE Connectivity 1SNA199069R0000, type D4/6.ADO, is a red feed-through terminal block from the Entrelec ADO range, designed for compact and dependable industrial wiring. It combines the ADO System with a screw-clamp connection, providing a practical interface between ADO-connected conductors and conventional screw-terminated wiring within control panels and automation equipment.
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. Its screw-clamp side accommodates flexible conductors from 0.22–4 mm² and rigid conductors from 0.2–4 mm², giving panel builders flexibility across common industrial conductor sizes.
At just 6 mm wide, the 1SNA199069R0000 is well suited to high-density DIN rail terminal assemblies. Its red polyamide housing provides clear visual circuit identification, carries a UL 94 V-0 flammability classification and provides IP20 protection at the main terminals, while the specified operating temperature range extends from -55 to +110 °C.
Key Advantages
- Combines ADO System and screw-clamp termination in one compact feed-through terminal.

Compact ADO and Screw-Clamp Connectivity
The D4/6.ADO combines Entrelec ADO connection technology with a conventional screw clamp in a single feed-through terminal. This hybrid arrangement allows ADO-based wiring to interface with standard screw-connected conductors while retaining the modular installation advantages of a DIN rail terminal system. It is particularly useful in control and automation panels where different conductor termination methods need to be integrated efficiently.
Its 6 mm-wide housing allows terminal rows to remain compact, while the 17.5 A current rating, 1000 V rated voltage and 8 kV impulse withstand rating provide robust electrical performance. The red housing also makes this specific variant easy to distinguish from grey, green, yellow, beige and other D4/6.ADO colour versions within complex terminal assemblies.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine control wiring.
- Signal and auxiliary circuits.
- ADO-to-screw wiring interfaces.
- Colour-coded terminal assemblies.
- DIN rail control and distribution systems.
- OEM machinery and industrial electrical equipment.
