Why Choose the TE Connectivity D4/6.D2.ADO Double-Deck Terminal Block?
The TE Connectivity 1SNA199242R0200 D4/6.D2.ADO is a compact grey double-deck feed-through terminal block designed to increase wiring density in industrial control panels, machinery and automation systems. Part of the established ENTRELEC SNA ADO range, it combines ADO insulation displacement technology with conventional screw clamp connections in a space-saving two-level design.
The D4/6.D2.ADO provides two independent feed-through circuits within a terminal only 6 mm wide. It has a rated cross-section of 1.5 mm², a rated current of 17.5 A and a rated voltage of 800 V, making it well suited to compact control and signal wiring applications.
The ADO connection accepts conductors from 0.34–1.5 mm² and supports up to two wires per ADO connection, while the screw-clamp interface provides a familiar termination method on the opposite side. Mounting on standard TH35-7.5 and TH35-15 DIN rails, together with IP20 main-terminal protection and a wide -55 to +110 °C operating range, supports dependable industrial installation.

Space-Saving Double-Deck ADO Connections
Double-deck terminal blocks increase wiring density by placing two independent connection levels within a single terminal footprint. At only 6 mm wide, the D4/6.D2.ADO enables panel builders to accommodate two feed-through circuits while conserving valuable DIN rail space in densely populated electrical cabinets.
The combination of the ENTRELEC ADO System and standard screw clamp technology provides flexibility during installation. ADO insulation displacement connections support rapid, repeatable conductor termination, while the screw-clamp side provides a familiar connection method for conventional panel wiring, making the terminal particularly useful for automation and process-control applications.
Typical Applications
- High-density industrial control panels.
- Factory automation systems.
- Machine control cabinets.
- PLC input and output wiring.
- Instrumentation and process-control systems.
- Signal and control circuits.
- Switchgear and electrical distribution equipment.
- Compact DIN rail terminal assemblies.
