1sna299556r0100 – dre 4/6 ado

Why Choose the TE Connectivity DSE4/6.ADO Terminal Block?

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.

Key Advantages

• Combines ADO and screw-clamp connections within one compact terminal.
• Special without-rib configuration for use at the extremity of a compatible terminal block assembly.
• Compact 6 mm width supports high-density panel construction.
• 17.5 A rated current and 800 V rated voltage.
• ADO connection accepts up to two wires per connection within the specified conductor capacities.
• Screw-clamp side accommodates conductors up to 4 mm².
• IP20 protection and UL94 V0 insulating material.
• Wide -55 to +110 °C operating-temperature range.

Space-Saving ADO and Screw-Clamp Connectivity

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.

Typical Applications

• Terminal block assembly extremities.
• Compact industrial control panels.
• PLC and automation cabinets.
• Machine control and instrumentation wiring.
• High-density DIN rail terminal assemblies.
• Process-control equipment.
• Industrial power and signal distribution.
• OEM machinery and electrical panel construction.
