Why Choose the TE Connectivity D1,5/6,ADO,D2,NF Railway Terminal Block?

The TE Connectivity D1,5/6,ADO,D2,NF, manufacturer part number 1SNA400291R0200, is a compact double-deck railway terminal block designed for space-efficient signal wiring in electrical panels and rail applications. Part of the Entrelec SNA HD / ADO terminal block range, it combines two connection levels within a narrow terminal profile for high-density wiring installations.

The terminal uses ADO insulation displacement connection technology, allowing conductors to be terminated without conventional screw clamping. This connection principle supports efficient assembly and dependable electrical contact while helping reduce wiring time in control, signalling and equipment installations.

With a 6 mm pitch, 1 A rated current and 80 V rated voltage, the D1,5/6,ADO,D2,NF is intended primarily for signal circuits. Its beige housing measures approximately 45.5 mm high × 6 mm wide × 41 mm deep and mounts onto standard 35 mm DIN rail.

Key Advantages

• Compact double-deck design provides two connection levels while conserving DIN rail space.
• ADO insulation displacement termination supports fast and reliable conductor connection.
• 6 mm terminal pitch enables high-density panel wiring.
• Designed for railway and signal circuit applications.
• Standard 35 mm DIN rail mounting simplifies integration into electrical assemblies.
• IP20 terminal protection supports safe installation within suitable electrical enclosures.

Reliable High-Density Wiring for Railway and Control Systems

Double-deck terminal blocks provide two wiring levels within the footprint normally occupied by a single terminal position. This makes the TE Connectivity D1,5/6,ADO,D2,NF particularly useful where designers need to maximise wiring density while maintaining an organised and serviceable terminal arrangement.

Its ADO insulation displacement connection system is designed to establish electrical contact through the conductor insulation during termination, avoiding a conventional screw connection. Combined with DIN rail mounting and a compact 6 mm width, this makes the terminal well suited to structured signal wiring in railway equipment, automation panels and other industrial control assemblies.

Typical Applications

• Railway signalling and control equipment.
• Rolling stock electrical assemblies.
• Industrial signal and control circuits.
• Automation and instrumentation panels.
• High-density DIN rail terminal assemblies.
• Electrical cabinets and equipment wiring.
