1sna290186r2200 – d2,5/5,de2,l

Why Choose the TE Connectivity D2.5/5.DE2.L 1SNA290186R2200 Component Terminal Block?

The TE Connectivity / ENTRELEC D2.5/5.DE2.L 1SNA290186R2200 is a double-level spring terminal block with component-holder functionality, designed for compact electrical and electronic circuit integration in industrial control panels. The terminal has an open upper circuit that enables electronic components to be incorporated into the terminal assembly, making it a practical solution where connection and component functions need to be combined within limited panel space.

Part of the ENTRELEC SNA spring terminal block range, the D2.5/5.DE2.L uses spring-clamp connection technology to provide consistent conductor contact pressure independently of the operator. Front wiring access simplifies conductor insertion and maintenance, while the double-level design provides two functional levels within a compact 5 mm width.

The terminal is rated at 20 A and 500 V, with a rated cross-section of 2.5 mm². Its grey polyamide housing, IP20 terminal protection and compatibility with standard 35 mm DIN rails make it suitable for professional automation, control and instrumentation assemblies.

Compact Component Integration with Spring-Clamp Connectivity

The D2.5/5.DE2.L combines terminal connection and component-holder functionality within a compact double-level format. Electronic components can be incorporated into the terminal arrangement, allowing designers to create application-specific interface, signalling or circuit functions while retaining an organised modular terminal structure.

Spring-clamp technology maintains conductor contact pressure without relying on a manually applied screw torque and automatically compensates for conductor settling over time. Together with front wiring access and 35 mm DIN rail mounting, this makes the 1SNA290186R2200 well suited to densely populated industrial control and automation panels where efficient installation and dependable connectivity are required.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Electronic component integration within terminal assemblies.
• Machine building and OEM control systems.
• Process control and instrumentation panels.
• Interface and signalling circuits.
• Compact double-level wiring installations.
• Industrial control and distribution systems.
