1SNA199480R2600 – D1.5/6D2 ADO

Why Choose the TE Connectivity D1.5/6.D2.ADO 1SNA199480R2600 Double-Deck Terminal Block?

The TE Connectivity D1.5/6.D2.ADO 1SNA199480R2600 is a grey double-deck feed-through terminal block from the ENTRELEC SNA ADO range. It incorporates two independent feed-through circuits within a single 6 mm wide terminal, helping panel builders increase wiring density while conserving valuable DIN rail space.

Both levels use the TE Connectivity ADO insulation displacement connection system, providing rapid conductor termination without conventional screw clamping. The terminal has a rated cross-section of 1.5 mm², an IEC rated current of 17.5 A and a rated voltage of 800 V, making it well suited to industrial control, automation and instrumentation wiring.

The D1.5/6.D2.ADO measures approximately 93 × 6 × 68 mm (H × W × D) and provides IP20 protection at the main terminals. Designed for TH35-7.5 and TH35-15 DIN rails, it combines high-density double-level wiring with polyamide insulation, UL94 V-0 flammability performance and an operating temperature range of -55 to +110 °C.

Key Advantages

• Two independent feed-through circuits in one compact terminal block.
• Double-deck construction helps reduce the DIN rail space required for high-density wiring.
• Only 6 mm wide despite providing four conductor connection positions.

Reliable High-Density ADO Wiring

Double-deck terminal blocks allow two circuits to be accommodated within the rail footprint normally associated with a single terminal position. The D1.5/6.D2.ADO uses this principle to provide two independent feed-through circuits within a width of only 6 mm, making it particularly useful for high-density industrial control cabinets.

The ADO System provides insulation displacement connections on both levels and supports up to two wires per connection. Combined with a 17.5 A IEC current rating, 800 V rated voltage and robust polyamide housing, the terminal provides a compact and dependable solution for control applications subject to vibration, shock and demanding environmental conditions.

Typical Applications

• High-density industrial control panels.
• PLC and factory automation cabinets.
• Machine control and signalling circuits.
• Process control and instrumentation systems.
• Industrial equipment with restricted DIN rail space.
• Double-level control and distribution wiring.
