The TE Connectivity M4/6.D2.1 1SNA115126R0100 is a grey double-deck feed-through screw clamp terminal block with partition designed for reliable signal connections in industrial control panels, machinery and automation systems. As part of the established TE Connectivity ENTRELEC SNA terminal block series, it combines two-level wiring capability with a compact DIN rail footprint.
This terminal block uses proven screw clamp termination technology to provide secure conductor connections and straightforward installation and maintenance. The double-deck configuration allows multiple connections to be arranged vertically, helping engineers increase wiring density where DIN rail space is limited, while the integrated partition provides separation within the terminal arrangement.
With a nominal conductor size of 4 mm², a maximum contact current rating of 32 A and an operating voltage of 800 V AC, the M4/6.D2.1 is well suited to industrial signal and control wiring. Its compact 6 mm spacing, IP20 protection and compatibility with G32 and TH35 DIN rails make it a versatile choice for professional panel building.
Double-deck terminal blocks provide two levels of conductor termination within a compact footprint, allowing panel builders to increase connection density without significantly increasing the required DIN rail length. This makes them particularly useful in control cabinets where a large number of signal connections must be accommodated within limited space.
The M4/6.D2.1 combines this space-efficient configuration with screw clamp termination and an integrated partition. Its SNA-series design, broad DIN rail compatibility and robust insulating construction make it suitable for organised, maintainable wiring in industrial automation and electrical control systems.
