TE Connectivity M4/7.D2.1 1SNA115127R0200 is a grey 4 mm² double-deck screw-clamp feed-through terminal block rated at 32 A and 800 V for high-density industrial DIN rail wiring.
Why Choose the TE Connectivity M4/7.D2.1 Double-Deck Terminal Block 1SNA115127R0200?
The TE Connectivity M4/7.D2.1 1SNA115127R0200 is a compact double-deck screw-clamp feed-through terminal block from the ENTRELEC SNA range, designed for high-density industrial wiring and control-panel applications. By providing two independent connection levels within a single 7 mm wide terminal, it enables panel builders to increase wiring density while maintaining an organised and accessible installation.
The M4/7.D2.1 uses proven screw-clamp connection technology for secure conductor termination and accommodates flexible conductors from 0.22–4 mm² and rigid conductors from 0.2–4 mm². The two levels are electrically independent, making the terminal suitable for routing two separate circuits through the same compact terminal-block footprint.
Rated at 32 A and 800 V, the M4/7.D2.1 provides robust electrical performance for industrial control and distribution systems. Its grey polyamide insulating body is rated UL 94 V-0, while compatibility with G32, TH35-7.5 and TH35-15 DIN rails provides installation flexibility across a wide variety of industrial enclosures and control cabinets.
Key Advantages
Space-saving double-deck terminal block with two independent circuits.
32 A rated current for dependable industrial electrical connections.
800 V rated voltage for demanding control and distribution applications.
Compact 7 mm width helps maximise wiring density inside control panels.
Mounts on both symmetrical and asymmetrical DIN rail formats for installation flexibility.
Key Features

Grey polyamide insulating housing with UL 94 V-0 flammability classification.
Reliable High-Density Wiring for Industrial Control Panels
Double-deck terminal blocks provide two connection levels within approximately the same rail footprint required by a conventional single-level terminal. This allows engineers to increase connection density without unnecessarily increasing enclosure size, making them particularly valuable in automation panels and machinery where DIN rail space is limited.
The M4/7.D2.1 combines this space-saving configuration with established ENTRELEC screw-clamp technology. Its two electrically independent feed-through circuits, broad conductor compatibility and multiple DIN rail mounting options make it a versatile terminal for structured industrial wiring and long-term panel maintenance.
Typical Applications
Industrial electrical control panels.
PLC and automation cabinets.
Machine building and OEM equipment.
Process control and instrumentation systems.
Power and signal distribution assemblies.
High-density DIN rail wiring installations.
