Why Choose the TE Connectivity D2.5/5.DE2.D2.L 1SNA290188R0400 Component Terminal Block?

The TE Connectivity / ENTRELEC D2.5/5.DE2.D2.L 1SNA290188R0400 is a double-level spring-clamp component terminal block designed to combine conductor termination with integrated electronic circuit functionality in compact industrial control panels. This specialised version incorporates two diodes, making it suitable for applications requiring diode-based signal routing, isolation or interface functions directly within the terminal assembly.

Part of the ENTRELEC SNA spring terminal block range, the D2.5/5.DE2.D2.L provides two connection levels within a compact 5 mm width. Spring-clamp technology provides consistent conductor contact pressure without depending on screw tightening torque, while front wiring access simplifies installation, testing and maintenance in densely populated control cabinets.

The integrated diode configuration is rated at 250 V and 1 A, with the cathode connected to the lower level. The terminal itself provides a 2.5 mm² nominal conductor size, 20 A main-circuit rated current, an IP20 degree of protection and a grey insulating housing for professional industrial installations.

Key Advantages

• Double-level construction maximises connection density within a 5 mm footprint.
• Integrated two-diode circuit provides component functionality directly within the terminal assembly.
• Diodes rated at 250 V, 1 A for suitable interface and control circuit applications.
• Spring-clamp connection technology maintains consistent conductor contact pressure.
• Front wiring entry provides convenient access during installation and servicing.
• Integrated component functionality can reduce the need for separately mounted electronic components.

Integrated Diode Functionality with Spring-Clamp Connectivity

The D2.5/5.DE2.D2.L combines terminal connection and electronic component functionality in a compact modular format. Its integrated two-diode arrangement enables diode functions to be incorporated directly into the terminal row, supporting organised interface, signalling and control circuit designs while reducing the need for separate component mounting.

Spring-clamp technology maintains conductor contact pressure independently of operator-applied screw torque and compensates automatically for conductor settling. Together with front wiring access, clearly visible marking positions and test facilities associated with the SNA spring terminal system, the 1SNA290188R0400 provides a practical solution for compact industrial automation and control wiring.

Typical Applications

• Industrial electrical control panels.
• PLC input and output interface circuits.
• Automation and process control cabinets.
• Diode isolation and signal-routing circuits.
• Machine building and OEM control systems.
• Instrumentation and signalling circuits.
• Compact double-level terminal assemblies.
