Why Choose the TE Connectivity M4/6.DE1.D Double-Deck Diode Terminal Block?
The TE Connectivity 1SNA115371R2600 M4/6.DE1.D is a specialised 4 mm² double-deck diode terminal block with one negative output, designed for compact signal conditioning and circuit interfacing within industrial control panels and automation systems. Part of the established ENTRELEC SNA screw-clamp terminal range, it combines two connection levels with an integrated diode function in a space-saving 6 mm-wide housing.
The M4/6.DE1.D incorporates a diode within the terminal assembly, allowing directional current flow to be implemented directly at the terminal level without requiring a separately mounted component. Its double-deck construction increases connection density while dependable screw-clamp terminals provide secure conductor termination for industrial wiring applications.
Rated at 20 A and 500 V, the M4/6.DE1.D accommodates rigid and flexible conductors up to 4 mm². The terminal has an IP20 protection rating and can be mounted on G32, TH35-7.5 and TH35-15 DIN rails, making it a practical solution for PLC interfaces, control circuits, signal systems and machine-building applications.

Compact Diode Integration for Industrial Control Circuits
Diode terminal blocks allow diode functionality to be incorporated directly into a terminal strip, helping reduce separate component wiring and simplify control cabinet layouts. The integrated diode permits current to flow in the required direction and is useful in applications such as signal isolation, suppression, logic interfacing and control circuit conditioning.
The M4/6.DE1.D combines this component functionality with a double-deck terminal arrangement, providing increased wiring density in a narrow 6 mm module. Its screw-clamp connections, DIN rail compatibility and industrial operating temperature range make it suitable for reliable integration into automation, instrumentation and machine control systems.
Typical Applications
- PLC input and output interface circuits.
- Industrial automation control panels.
- Signal isolation and directional control circuits.
- Machine control and instrumentation systems.
- Relay and solenoid control circuits.
- High-density DIN rail terminal assemblies.
