1sna299489r0700 – ds4/6 ado

Why Choose the TE Connectivity DS4/6.ADO Terminal Block?

The TE Connectivity / Entrelec DS4/6.ADO, part number 1SNA299489R0700, is a compact grey feed-through miniblock terminal combining a conventional screw-clamp connection with Entrelec's ADO connection system. It is designed for industrial applications where panel space is restricted and dependable conductor termination is essential.

The DS4/6.ADO has a slim 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 screw-clamp side accepts rigid conductors from 0.2–4 mm² and flexible conductors from 0.22–4 mm².

Designed for mounting on standard TH 35-7.5 and TH 35-15 DIN rails, the DS4/6.ADO measures approximately 42.3 × 6 × 28 mm and weighs just 5 g. Its IP20 polyamide construction, wide operating-temperature range and V0 flammability classification make it well suited to compact industrial control and automation assemblies.

Key Advantages

• Combines screw-clamp and ADO connection technologies in one compact terminal.
• Only 6 mm wide, helping maximise DIN rail space in dense control panels.
• 17.5 A rated current for industrial power and control circuits.
• 800 V rated voltage provides substantial electrical capability for its compact size.
• Screw-clamp connection accommodates conductors up to 4 mm².
• IP20 protection at the main terminals.
• Wide -55 to +110 °C operating-temperature range.
• Mounts on standard 35 mm DIN rails for straightforward panel integration.

Compact ADO Feed-Through Connection for Industrial Wiring

The DS4/6.ADO combines the flexibility of a conventional screw-clamp termination with Entrelec's ADO connection system. This configuration makes it particularly useful where different conductor-termination methods need to be accommodated within the same compact feed-through circuit while maintaining an organised DIN rail layout.

Its 6 mm pitch, 17.5 A current rating and 800 V rated voltage provide useful electrical performance in a space-saving miniblock format. The polyamide V0 housing, IP20 protection and broad temperature capability further support use in demanding industrial automation and machine-control environments.

Typical Applications

• 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.
