Why Choose the TE Connectivity 1SNA199064R2300 D4/6.ADO.2 Feed-Through Terminal Block?
The TE Connectivity 1SNA199064R2300, type D4/6.ADO.2, is a grey feed-through terminal block with an integrated 2 mm test socket, designed for industrial control, automation and signal wiring. Part of the Entrelec SNA ADO range, it combines the ADO System with a conventional screw-clamp connection, providing a practical interface between ADO-connected wiring and standard screw-terminated conductors.
The D4/6.ADO.2 has a rated cross-section of 1.5 mm², a rated current of 17.5 A and an IEC rated voltage of 800 V. Its integrated 2 mm diameter test socket provides a convenient point for compatible test equipment, supporting circuit measurement and commissioning without disturbing the main conductor connections.
With a compact 6 mm width, dimensions of approximately 45 mm high × 41 mm deep and IP20 protection at the main terminals, the 1SNA199064R2300 is well suited to densely populated DIN rail assemblies. Its broad -55 to +110 °C operating temperature range further supports dependable use in demanding industrial electrical environments.

ADO Connectivity with Integrated Test Access
The D4/6.ADO.2 combines two useful functions within a compact terminal profile. Its hybrid screw-clamp and ADO configuration enables conventional panel wiring to interface with the Entrelec ADO connection system, while the ADO side can accommodate up to two conductors per connection. This provides flexibility when configuring industrial control and signal circuits.
The distinguishing feature of the D4/6.ADO.2 is its integrated 2 mm test socket. A compatible test plug can be connected at this point to perform circuit measurements during commissioning, diagnostics and maintenance without disconnecting the main wiring. This makes the terminal particularly useful where regular electrical testing is required within compact control-panel assemblies.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Signal and instrumentation circuits.
- Electrical testing and commissioning circuits.
- Machine control wiring.
- ADO-to-screw wiring interfaces.
- DIN rail terminal block assemblies.
- OEM machinery and industrial equipment.
