1sna299505r0700 – db4/6 ado grey

Why Choose the TE Connectivity 1SNA299505R0700 DB4/6.ADO Grey Terminal Block?

The TE Connectivity 1SNA299505R0700, also identified as DB4/6.ADO, is a compact grey ADO-to-screw-clamp feed-through miniblock terminal from the Entrelec ADO System range. It combines the speed and reliability of ADO conductor termination on one side with a conventional screw-clamp connection on the other, providing flexibility for industrial control-panel wiring.

The DB4/6.ADO has a nominal cross-section of 1.5 mm², a compact 6 mm width and an IEC rating of 17.5 A at 800 V. The screw-clamp side accommodates rigid conductors from 0.2 to 4 mm² and flexible conductors from 0.22 to 4 mm², allowing larger conventional conductors to interface with the ADO connection system.

Manufactured from durable polyamide with UL 94 V-0 flammability performance, the terminal provides IP20 protection and operates from -55 to +110 °C. Its compact miniblock construction makes it particularly useful for industrial applications where installation space is restricted but dependable conductor termination remains essential.

Key Advantages

• Combines ADO and screw-clamp connection technologies in one compact terminal.
• 6 mm width helps minimise the space required by terminal assemblies.
• 17.5 A IEC rated current supports industrial control and distribution circuits.
• 800 V IEC rated voltage provides versatile electrical performance.
• Screw-clamp connection accepts conductors up to 4 mm².
• IP20 protection supports safe integration into enclosed electrical equipment.

Reliable ADO-to-Screw-Clamp Connections for Compact Wiring

The DB4/6.ADO combines two complementary conductor-termination methods. The ADO System connection provides fast, consistent termination, while the conventional screw-clamp side offers flexibility for rigid and flexible conductors up to 4 mm². This makes the terminal particularly useful when an ADO wiring system needs to interface with conventionally terminated field or panel conductors.

Its compact 6 mm profile, 17.5 A current rating and 800 V IEC voltage rating provide useful electrical capability without consuming unnecessary installation space. Polyamide insulation, IP20 protection and a broad temperature range further support dependable service in industrial control and automation equipment.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Compact terminal and junction assemblies.
• Interfacing ADO wiring with conventional screw-clamp conductors.
• Industrial power, signal and control circuits.
