1sna399514r2300 – ds2,5/5,ado

Why Choose the TE Connectivity DS2.5/5.ADO Feed-Through Terminal Block?

The TE Connectivity 1SNA399514R2300, also identified as DS2.5/5.ADO, is a compact feed-through DIN rail terminal block combining ADO insulation displacement and screw-clamp connection technologies. Part of the Entrelec SNA ADO miniblock range, it is specifically designed for control panels and industrial installations where available wiring space is restricted.

The DS2.5/5.ADO combines the speed and reliability of the ADO System with the versatility of a conventional screw-clamp connection. The ADO side allows conductors to be terminated without stripping their insulation, while the screw-clamp side provides a familiar connection method for installation and maintenance work. The ADO connection can accommodate up to two conductors per connection point.

With a narrow 5 mm pitch, a nominal conductor cross-section of 1 mm² and an IEC rated current of 13.5 A, this grey miniblock provides a space-efficient connection solution for control and signal wiring. It mounts on standard 35 mm DIN rail and is suitable for densely populated automation, machinery and electrical control assemblies.

Key Advantages

• Compact 5 mm miniblock design for installations where DIN rail space is limited.
• Combines ADO insulation displacement and screw-clamp connections in one terminal block.
• 13.5 A IEC rated current for industrial control and signal wiring.
• ADO technology eliminates conductor stripping on the insulation displacement connection side.
• Supports up to two conductors per ADO connection point.
• Standard 35 mm DIN rail mounting simplifies integration into industrial control panels.

Key Features

• TE Connectivity / Entrelec SNA ADO miniblock.
• DS2.5/5.ADO feed-through configuration.
• Hybrid ADO System and screw-clamp connection technology.
• 1 mm² nominal conductor cross-section.
• 13.5 A IEC rated current.
• 800 V rated voltage.
• Solid conductor capacity from 0.2–1 mm².
• Flexible conductor capacity from 0.22–1 mm².
• Single-level terminal block with a compact 5 mm width.
• Grey thermoplastic insulating body with V0 flammability classification.

Reliable Hybrid Connections for Compact Control Panels

Feed-through terminal blocks provide an organised electrical connection between incoming and outgoing conductors while keeping panel wiring accessible for installation and maintenance. The DS2.5/5.ADO is particularly useful where space is restricted because its 5 mm profile allows a high connection density on standard DIN rail.

By combining Entrelec ADO technology with a standard screw clamp, the DS2.5/5.ADO gives panel builders the benefits of rapid insulation displacement termination together with the flexibility of conventional screw wiring. This hybrid arrangement makes the terminal well suited to industrial automation, machine control and other applications requiring compact, dependable conductor connections.

Typical Applications

• Industrial control and automation panels.
• Compact PLC and I/O wiring assemblies.
• Machine control cabinets and OEM equipment.
• Instrumentation and signal wiring.
• Switchgear and electrical distribution assemblies.
• High-density DIN rail installations with restricted panel space.
