The TE Connectivity DSE2,5/8,ADO 1SNA299559R1400 is a compact ADO IDC feed-through DIN rail terminal block designed for reliable conductor termination in industrial control, automation and electrical panel applications. As part of the established Entrelec ADO Miniblocks range, it provides a space-efficient connection solution for installations where dependable wiring and compact dimensions are essential.
The terminal uses the ADO insulation displacement connection system, providing fast and secure conductor termination without a conventional screw-clamp connection. The ADO system is particularly suited to demanding control applications exposed to vibration, shock and corrosion, while the terminal can accommodate up to two conductors per connection.
With an IEC rated current of 24 A, rated voltage of 1000 V and rated conductor cross-section of 2.5 mm², the DSE2,5/8,ADO provides dependable connectivity for industrial control and distribution circuits. Its compact 8 mm spacing, single-level construction and compatibility with standard TH35 DIN rails make it ideal for organised, high-density control cabinet installations.
ADO insulation displacement technology provides a secure electrical connection by terminating conductors through a dedicated connection system rather than a conventional screw clamp. This makes ADO terminals particularly useful for industrial control systems where fast installation, consistent connection quality and resistance to vibration are important.
The DSE2,5/8,ADO combines a compact miniblock format with a 2.5 mm² connection capacity and 8 mm spacing. Its robust polyamide construction, DIN rail compatibility and ability to accommodate up to two wires per connection make it well suited to densely populated control cabinets and industrial automation equipment.
