The TE Connectivity / Entrelec DSE4/6.ADO, part number 1SNA299556R0100, is a grey feed-through miniblock terminal combining screw-clamp and ADO connection technologies. The manufacturer designation for this exact part number is DSE4/6.ADO, and it is the version without the separating rib for installation at the extremity of a compatible terminal block assembly.
Designed for applications where DIN rail space is restricted, the DSE4/6.ADO has a compact 6 mm pitch and a rated cross-section of 1.5 mm². Its main circuit is rated at 17.5 A and 800 V, while the ADO connection accepts rigid conductors from 0.28–1.5 mm² and flexible conductors from 0.34–1.5 mm².
The conventional screw-clamp side accommodates rigid conductors from 0.2–4 mm² and flexible conductors from 0.22–4 mm². With IP20 protection, V0 polyamide insulation and compatibility with standard TH 35 DIN rails, this compact terminal provides a flexible connection solution for industrial automation, machinery and control-panel wiring.
The DSE4/6.ADO provides two complementary conductor-termination methods within a terminal only 6 mm wide. The ADO connection is designed for rapid, reliable conductor termination, while the screw-clamp side provides compatibility with conventional panel wiring and accommodates conductors up to 4 mm².
Unlike the ribbed DS4/6.ADO version, the DSE4/6.ADO is manufactured without the separating rib and is intended for use at the extremity of a compatible terminal block assembly. This configuration, combined with its 17.5 A rating, 800 V IEC voltage rating and compact dimensions, makes it particularly useful in space-constrained industrial control installations.
