1sna115897r0700 – d2.5/5d2.ado grey v2 double deck

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

The TE Connectivity 1SNA115897R0700 D2.5/5.D2.ADO is a compact double-deck feed-through terminal block designed for high-density industrial control, automation and signal wiring. Part of the established ENTRELEC ADO terminal block range, it combines two connection levels within a narrow 5 mm footprint to help maximise usable DIN rail space.

The D2.5/5.D2.ADO combines screw-clamp and ADO connection technology, providing a versatile interface for organised field and internal panel wiring. Its two-level construction allows multiple circuits to be terminated vertically rather than requiring additional DIN rail width, making it particularly useful in densely populated control cabinets.

Featuring a 1 mm² rated cross-section, 5 mm spacing and an 8 kV rated impulse withstand voltage, the D2.5/5.D2.ADO provides dependable electrical insulation performance in industrial installations. The grey polyamide terminal measures 84.5 × 5 × 68.5 mm and is designed for mounting on TH35-7.5 and TH35-15 DIN rails.

Key Advantages

• Double-deck construction increases wiring density while occupying only 5 mm of DIN rail width.
• Combines screw-clamp and ADO connection technology within one terminal block.
• Two connection levels enable efficient organisation of multiple circuits.
• 8 kV impulse withstand voltage provides robust insulation performance.
• Compact grey polyamide housing is designed for industrial terminal assemblies.
• Compatible with TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715.

High-Density Wiring with Screw-Clamp and ADO Connections

Double-deck terminal blocks arrange electrical connections vertically, allowing two connection levels to occupy the DIN rail width normally associated with a single terminal. The TE Connectivity D2.5/5.D2.ADO uses this configuration to provide a compact 5 mm-wide feed-through solution for control, signal and automation wiring where terminal density is important.

The combination of screw-clamp and ADO termination provides flexibility when organising field and internal panel connections. Together with an 8 kV impulse withstand rating, polyamide insulation and compatibility with standard 35 mm DIN rails, the D2.5/5.D2.ADO provides a practical solution for compact and modular industrial terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• PLC input and output wiring.
• Machine and factory automation systems.
• Instrumentation and process-control cabinets.
• High-density signal wiring assemblies.
• Modular DIN rail terminal installations.
