1sna290182r2600 – d2.5/5.de1.d.l diode

Why Choose the TE Connectivity D2.5/5.DE1.D.L 1SNA290182R2600 Diode Terminal Block?

The TE Connectivity / Entrelec D2.5/5.DE1.D.L 1SNA290182R2600 is a double-level spring-clamp component terminal block with an integrated 1N4007 diode, designed for signal conditioning, circuit protection and testing within industrial control panels and automation systems. Its built-in component functionality reduces the need for separately mounted diode assemblies and helps create compact, organised DIN rail installations.

The D2.5/5.DE1.D.L uses spring-clamp connection technology, providing consistent contact pressure independently of installer-applied screw torque. Front wiring entry makes conductor installation straightforward, while integrated features including a single jumper system, clearly visible top marking and test sockets support efficient panel assembly, commissioning and maintenance.

With a 2.5 mm² rated cross-section, 20 A main-circuit rated current and 500 V main-circuit rated voltage, this two-level terminal accepts flexible conductors from 0.12–2.5 mm² and rigid conductors from 0.12–4 mm². Its compact 5 mm width, grey polyamide housing, IP20 protection and UL 94 V-0 flammability classification make it suitable for demanding industrial electrical installations.

Integrated Diode Terminal Technology for Industrial Control Circuits

Component terminal blocks combine standard conductor termination with electrical components directly within the DIN rail terminal assembly. Integrating a diode into the terminal can simplify control and signal circuits, reduce separate component wiring and help create a more compact and serviceable panel layout. Diodes are commonly used where current needs to flow in a defined direction or where circuit protection and signal isolation functions are required.

The D2.5/5.DE1.D.L combines this functionality with a two-level spring-clamp design and compact 5 mm footprint. Its front wiring entry, jumper system, top marking facility and test sockets make it particularly suitable for automation and control applications where high connection density, accessible testing and reliable spring-clamp termination are important.

Typical Applications

• Industrial control panels and electrical cabinets.
• PLC input and output signal circuits.
• Automation and process control systems.
• Signal isolation and directional current applications.
• Relay, solenoid and control circuit interfaces.
• Machine-building and OEM electrical systems.
• Instrumentation and monitoring circuits.
• High-density DIN rail terminal installations.
