1SNA199561R2200 – D2,5/5,ADO

Why Choose the TE Connectivity 1SNA199561R2200 D2.5/5.ADO Terminal Block?

The TE Connectivity 1SNA199561R2200, also known as the D2.5/5.ADO, is a green feed-through DIN rail terminal block from the Entrelec SNA ADO range. Designed for industrial control panels, machinery and automation systems, it combines the speed of ADO insulation displacement technology with a conventional screw-clamp connection in a compact 5 mm wide housing.

The D2.5/5.ADO uses a screw clamp-to-ADO connection arrangement, allowing installers to benefit from the Entrelec ADO System while retaining a standard screw-clamp interface. The ADO connection can accommodate up to two wires per connection, helping simplify wiring and increase connection flexibility in densely populated electrical cabinets.

With a rated cross-section of 1 mm², a main-circuit rated current of 13.5 A and a rated voltage of 1000 V, the 1SNA199561R2200 provides dependable performance for industrial control and distribution circuits. Its IP20 main-terminal protection, polyamide insulation and compatibility with standard TH35 DIN rails make it a practical choice for professional panel construction.

Fast and Flexible ADO Feed-Through Connections

The Entrelec ADO System uses insulation displacement connection technology to provide rapid and reliable conductor termination without the conventional conductor preparation associated with many connection methods. On the D2.5/5.ADO, this technology is combined with a standard screw clamp, giving panel builders a hybrid connection solution that supports efficient installation while retaining a familiar screw-terminal interface.

The compact 5 mm profile helps maximise wiring density, while the ADO side can accommodate up to two wires per connection. Combined with its 1000 V rating, IP20 main-terminal protection and broad operating temperature range, the D2.5/5.ADO is well suited to industrial automation, machine building and control-panel wiring where reliable and space-efficient connections are required.

Typical Applications

• Industrial electrical control panels.
• PLC and automation system wiring.
• Machine building and OEM equipment.
• Process control and instrumentation cabinets.
• Factory automation systems.
• Control and auxiliary circuit connections.
• DIN rail installations requiring compact screw-clamp and ADO feed-through connections.
