1sna399518r0700 – dse2,5/5,ado

Why Choose the TE Connectivity DSE2.5/5.ADO Feed-Through Terminal Block?

The TE Connectivity 1SNA399518R0700, also identified as DSE2.5/5.ADO, is a compact feed-through terminal block combining ADO insulation displacement and screw-clamp connection technologies. Part of the Entrelec ADO miniblock range, this version is specifically designed without a rib for use at the extremity of a terminal block assembly, providing a practical solution where panel space is restricted.

The DSE2.5/5.ADO combines the advantages of the ADO System with a conventional screw-clamp connection. Its ADO side provides fast conductor termination and can accommodate up to two conductors per connection point, while the screw-clamp side accepts a broader range of conductor sizes and provides a familiar termination method for installers.

With a compact 5 mm pitch, an IEC rated current of 13.5 A and a rated voltage of 800 V, the DSE2.5/5.ADO is well suited to densely populated control and automation panels. Its grey insulating body mounts on standard 35 mm DIN rail, while the extremity configuration enables it to complete compatible terminal block assemblies efficiently.

Key Advantages

• Compact 5 mm miniblock design for space-restricted control panels.
• Without-rib extremity version designed for the end of compatible terminal block assemblies.
• Combines ADO insulation displacement and screw-clamp connections in one terminal.
• 13.5 A rated current and 800 V rated voltage.
• ADO connection supports up to two conductors per connection point.
• Standard 35 mm DIN rail mounting simplifies integration into industrial panels.

Key Features

• TE Connectivity / Entrelec ADO System miniblock.
• DSE2.5/5.ADO feed-through terminal configuration.
• Without rib for terminal block assembly extremity.
• Hybrid ADO / screw-clamp connection technology.
• 1 mm² nominal cross-section.
• 13.5 A IEC rated current.
• 800 V IEC rated voltage.
• 8,000 V impulse withstand voltage.
• ADO conductor capacity up to 1 mm².
• Screw-clamp conductor capacity up to 4 mm² solid or 2.5 mm² flexible.
• Grey housing with IP20 protection at the main terminals.

Reliable Hybrid Connections for Compact Control Panels

ADO miniblocks are designed for electrical installations where available DIN rail space is limited but dependable conductor termination remains essential. The DSE2.5/5.ADO combines compact construction with two connection methods, allowing panel builders to benefit from rapid ADO termination while retaining the flexibility of a standard screw clamp.

Unlike the ribbed DS2.5/5.ADO version, the DSE2.5/5.ADO is configured without a rib for placement at the extremity of a compatible terminal block assembly. This makes it particularly useful when building organised terminal strips for automation, instrumentation and machinery applications while maintaining the compact 5 mm terminal pitch.

Typical Applications

• Industrial control and automation panels.
• Terminal block assembly extremities.
• Compact PLC and I/O wiring systems.
• Machine control cabinets and OEM equipment.
• Instrumentation and signal circuits.
• High-density DIN rail installations where panel space is restricted.
