1sna290501r0000 – ds2,5/10,4l,yl

Why Choose the TE Connectivity 1SNA290501R0000 DS2.5/10.4L.YL Spring Terminal Block?

The TE Connectivity 1SNA290501R0000, also identified as DS2.5/10.4L.YL or DS2,5/10,4L,YL, is a compact four-connection feed-through spring terminal block designed for reliable conductor termination in industrial electrical panels and automation systems. Part of the established Entrelec Mini Blocks Spring range, it combines a space-efficient format with front-access wiring and dependable spring-clamp connection technology.

The DS2.5/10.4L.YL provides four conductor connections within a single-level terminal block, making it particularly useful where multiple conductors must be interconnected at a common potential. Spring-clamp technology maintains consistent contact pressure independently of operator tightening torque and automatically compensates for conductor creep, supporting reliable long-term electrical connections.

Featuring a 2.5 mm² rated cross-section, 10 mm spacing and distinctive yellow housing, the 1SNA290501R0000 is designed for mounting on standard TH35 DIN rails. Its compact dimensions and four-connection configuration make it suitable for high-density industrial control, machine-building and distribution applications.

Reliable Four-Connection Spring Terminal Wiring

Spring terminal blocks provide dependable conductor retention by applying continuous spring pressure to the electrical connection. Unlike screw-clamp terminals, the clamping force does not depend on installer-applied torque, while automatic compensation for conductor creep helps maintain connection integrity throughout the service life of the installation.

The DS2.5/10.4L.YL combines these benefits with four connections and front wiring entry, enabling multiple conductors to be interconnected neatly at a common potential. Its compatibility with standard 35 mm DIN rails allows straightforward integration into modular industrial terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Process control and instrumentation panels.
• Electrical distribution and marshalling systems.
• Multi-conductor feed-through connections.
