1sna399896r2300 – d1/5.d2.ado double deck

Why Choose the TE Connectivity D1/5.D2.ADO 1SNA399896R2300 Double-Deck Terminal Block?

The TE Connectivity D1/5.D2.ADO 1SNA399896R2300 is a grey double-deck feed-through terminal block featuring two independent circuits in a compact 5 mm-wide footprint. Part of the Entrelec ADO System range, it is designed for high-density industrial control wiring where panel space, connection reliability and installation efficiency are important.

Both levels use ADO System insulation-displacement connection technology, allowing conductors to be terminated without conventional stripping while maintaining dependable electrical contact. The double-deck arrangement provides two feed-through circuits in the rail space normally associated with a single-level terminal, making it particularly useful for PLC, automation and process-control installations.

The D1/5.D2.ADO has a 1 mm² rated cross-section, 13.5 A rated current and 630 V rated voltage. It also provides an 8 kV impulse withstand rating, IP20 protection at the main terminals and mounting compatibility with standard TH35 DIN rails.

Key Advantages

• Double-deck construction provides two feed-through circuits in one compact terminal footprint.
• 5 mm width supports high-density DIN rail installations.

Space-Saving Double-Deck ADO Connection Technology

Double-deck terminal blocks allow two independent electrical circuits to be accommodated vertically within a single DIN rail position. The D1/5.D2.ADO therefore helps increase wiring density without requiring additional rail length, making it especially useful in compact control cabinets with large numbers of signal and control connections.

Entrelec ADO System technology uses insulation-displacement termination to streamline conductor connection and is designed for demanding control applications. Combined with the terminal's two-level architecture and ability to accept up to two wires per connection, it provides an efficient solution for high-density industrial wiring.

Typical Applications

• High-density industrial control panels.
• PLC input and output wiring.
• Industrial automation cabinets.
• Process-control systems.
• Instrumentation and signal circuits.
• Machine-building electrical systems.
• Marshalling and interface panels.
• Space-constrained DIN rail terminal assemblies.
