Why Choose the TE Connectivity 1SNA199039R2200 D4/6.ADO Feed-Through Terminal Block?
The TE Connectivity 1SNA199039R2200, type D4/6.ADO, is a yellow feed-through terminal block combining the Entrelec ADO connection system with a conventional screw-clamp connection. This hybrid design provides installers with the advantages of ADO wiring on one side while retaining a standard screw connection on the other, making it a versatile choice for industrial control and automation wiring.
The D4/6.ADO has a rated cross-section of 1.5 mm², a rated current of 17.5 A and a rated voltage of 1000 V. The screw-clamp connection accepts flexible conductors from 0.22–4 mm² and rigid conductors from 0.2–4 mm², while the ADO system is designed to provide rapid, consistent conductor termination and can accommodate up to two wires per ADO connection.
At only 6 mm wide, the 1SNA199039R2200 provides a compact solution for densely populated terminal assemblies. Its polyamide insulating body carries a UL 94 V-0 flammability classification, provides IP20 protection at the main terminals and is designed for installation on standard TH35 DIN rails in industrial panels and machinery.

Hybrid ADO and Screw-Clamp Connection Technology
The D4/6.ADO combines two conductor-termination methods within one feed-through terminal. The ADO connection system provides rapid conductor termination and permits up to two wires at an ADO connection, while the opposite screw-clamp connection provides a familiar and adjustable termination method for conventional panel wiring. This combination is useful when interfacing ADO-wired circuits with standard screw-connected field or control wiring.
Its single-level 6 mm-wide construction enables efficient use of DIN rail space while maintaining ratings of 17.5 A and 1000 V. The polyamide housing, IP20 terminal protection and broad -55 to +110 °C operating range make the D4/6.ADO suitable for dependable use in industrial automation, machine control and electrical panel applications.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine control wiring.
- Signal and auxiliary circuits.
- ADO-to-screw wiring interfaces.
- DIN rail terminal block assemblies.
- OEM machinery and industrial equipment.
