1sna290342r1500 – d2,5/5,a,ll,l,v0

Why Choose the TE Connectivity 1SNA290342R1500 D2.5/5.A.LL.L Terminal Block?

The TE Connectivity 1SNA290342R1500, also identified as D2.5/5.A.LL.L or D2,5/5,A,LL,L,V0, is a compact double-deck spring terminal block designed for space-efficient electrical distribution and control wiring. Originating from the established Entrelec terminal block range, it provides multiple connection levels within a narrow footprint for high-density industrial panel installations.

The D2.5/5.A.LL.L uses spring-clamp connection technology to provide consistent conductor contact pressure with reduced dependence on installation torque. Its angled, front-access wiring arrangement helps simplify conductor insertion and maintenance, particularly where wiring space inside a control cabinet is restricted.

With a compact 5 mm width, grey housing and IP20 protection at the main terminals, the 1SNA290342R1500 is well suited to modular control panels, automation cabinets and electrical distribution assemblies where reliable, organised wiring and efficient use of DIN-rail space are required.

Key Advantages

• Compact double-deck terminal block for high-density control wiring.
• Only 5 mm wide to maximise available DIN-rail space.
• Spring-clamp connection technology provides reliable contact pressure.
• Angled front wiring entry improves conductor accessibility.
• IP20 protection at the main terminals.
• Modular construction suitable for industrial control and distribution panels.

Key Features

• TE Connectivity / Entrelec D2.5/5 series.
• Double-level terminal block construction.
• Spring connection system for dependable conductor retention.
• Grey insulating housing.
• Compact angled format designed to save panel space.
• Front-access conductor connection for convenient wiring.
• IP20 degree of protection at the main terminals.
• Designed for modular industrial electrical installations.

Space-Efficient Industrial Terminal Wiring

Double-deck terminal blocks provide two connection levels within the rail space normally occupied by a single-width terminal, helping designers increase wiring density without significantly enlarging the control panel. This makes them particularly useful in PLC cabinets, machinery control systems and process automation installations where large numbers of field conductors must be terminated neatly.

The spring connection principle used in the D2.5/5 family maintains contact pressure independently of screw tightening torque and helps compensate for conductor movement over time. Combined with front-access wiring, this provides a practical solution for reliable assembly, inspection and maintenance of industrial electrical circuits.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-building wiring systems.
• Process control installations.
• Electrical distribution and marshalling panels.
• High-density DIN-rail terminal assemblies.
