1sna399509r1700 – dr2,5/5,ado
TE Connectivity DR2.5/5.ADO 1SNA399509R1700 is a compact 13.5 A, 800 V feed-through miniblock terminal combining ADO insulation displacement and screw-clamp connections for space-efficient industrial DIN rail wiring.
Why Choose the TE Connectivity DR2.5/5.ADO Feed-Through Terminal Block?
The TE Connectivity DR2.5/5.ADO, part number 1SNA399509R1700, is a compact feed-through terminal block combining ADO insulation displacement and screw-clamp connection technologies. Designed for applications where DIN rail space is restricted, this Entrelec miniblock provides dependable conductor termination in industrial control panels, automation systems and machinery wiring.
The DR2.5/5.ADO combines the speed of the ADO System with the versatility of a conventional screw clamp. The ADO side allows conductors to be connected without traditional stripping and screw tightening, while the screw-clamp side supports standard prepared conductors. The ADO connection can accommodate up to two conductors per connection point, helping simplify compact wiring arrangements.
With a rated current of 13.5 A, rated voltage of 800 V and a compact 5 mm pitch, the DR2.5/5.ADO is engineered for dense terminal assemblies. It mounts on a TH 15-5.5 DIN rail, features an IP20 protection rating and has a compact overall size of approximately 31 × 5 × 28 mm.

Compact Feed-Through Wiring with ADO Technology
Feed-through terminal blocks provide a straightforward electrical connection between incoming and outgoing conductors while keeping wiring organised on a DIN rail. The DR2.5/5.ADO is particularly suited to installations where available panel space is limited, combining a narrow 5 mm profile with versatile dual connection technologies.
The ADO insulation displacement system reduces conductor preparation and installation steps, while the conventional screw-clamp connection allows integration with established wiring practices. This hybrid design makes the terminal useful for OEM machinery, automation equipment and industrial control assemblies where compact dimensions and flexible termination methods are important.
Typical Applications
- Compact electrical control panels.
- Industrial automation and PLC wiring.
- Machine building and OEM equipment.
- Instrumentation and signal circuits.
- Switchgear and distribution assemblies.
- High-density DIN rail terminal installations.
