1sna290191r2700 – d2,5/5,de,l
TE Connectivity 1SNA290191R2700 D2.5/5.DE.L is a two-level spring-clamp component terminal block rated at 20 A and 500 V with a 2.5 mm² rated cross-section for industrial control and automation wiring.
Why Choose the TE Connectivity D2.5/5.DE.L 1SNA290191R2700 Terminal Block?
The TE Connectivity 1SNA290191R2700, also identified as D2.5/5.DE.L, is a compact double-deck spring-clamp component terminal block designed for high-density electrical control panels, automation systems and industrial machinery. Part of the established ENTRELEC SNA spring terminal block range, it combines two connection levels within a space-saving 5 mm width.
This specialised component-holder terminal allows electronic components to be soldered into the double-deck terminal block, supporting components with a maximum thickness of 4 mm. Front wiring entry provides convenient conductor access, while the spring-clamp connection system delivers consistent contact pressure independently of the operator and provides automatic compensation for conductor creep.
With a rated cross-section of 2.5 mm², rated current of 20 A and rated voltage of 500 V, the D2.5/5.DE.L is suitable for demanding industrial control and signalling circuits. Its grey polyamide housing, IP20 protection and compatibility with standard 35 mm DIN rail systems make it a practical choice for professional panel building and industrial automation installations.

Reliable Spring-Clamp Connections for Industrial Control Panels
Spring-clamp terminal technology maintains conductor contact pressure without relying on installer-applied screw torque. This provides consistent electrical connections while automatically compensating for conductor creep, making spring terminals particularly useful in industrial environments where reliable long-term wiring connections are required.
The D2.5/5.DE.L combines this connection technology with a two-level component-holder design. Electronic components can be incorporated directly into the terminal arrangement, while the narrow 5 mm profile helps maximise wiring density inside control cabinets and machinery panels.
Typical Applications
- Industrial electrical control panels.
- PLC and automation control cabinets.
- Component and signalling circuits.
- Machine building and OEM electrical systems.
- Process control and instrumentation panels.
- High-density DIN rail terminal installations.
