Why Choose the TE Connectivity D1.5/6.ADO 1SNA199051R2600 Feed-Through Terminal Block?
The TE Connectivity D1.5/6.ADO 1SNA199051R2600 is a compact feed-through ADO terminal block designed for fast, reliable conductor termination in industrial control panels, automation systems and machinery. Part of the established Entrelec SNA terminal block range, it uses TE Connectivity’s ADO insulation displacement connection technology to eliminate conductor stripping and simplify panel wiring.
The D1.5/6.ADO supports rigid, stranded and flexible conductors from 0.34–1.5 mm² and allows up to two wires per connection. Its ADO-to-ADO feed-through configuration is particularly suited to control applications exposed to vibration, shock and corrosion, where consistent conductor retention and dependable electrical performance are important.
With a rated current of 17.5 A, rated voltage of 1000 V and an 8 kV impulse withstand voltage to IEC ratings, this grey terminal block provides strong electrical performance in a compact 6 mm pitch. It mounts on standard TH35 DIN rails, making it straightforward to integrate into modular industrial terminal assemblies.

Fast and Reliable ADO Terminal Connections
ADO insulation displacement technology enables conductors to be terminated without first stripping the insulation. The conductor is inserted into the connection point and secured by the ADO mechanism, helping reduce wiring time while maintaining a consistent electrical connection.
The D1.5/6.ADO is designed for demanding control applications where vibration, shock and corrosion may affect conventional connections. Its compact format, DIN rail compatibility and ability to accommodate up to two conductors per connection make it well suited to densely wired industrial panels.
Typical Applications
- Industrial control panels and switchboards.
- PLC and automation systems.
- Machine control wiring.
- Signal and control circuits.
- Transportation and railway electrical systems.
- OEM equipment and modular DIN rail assemblies.
