The TE Connectivity M4/6.D1.1 1SNA115204R2000 is a compact grey double-level feed-through screw clamp terminal block 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 secure screw termination with a space-efficient two-level configuration for high-density DIN rail wiring.
The M4/6.D1.1 provides two connection levels within a slim 6 mm width, allowing panel builders to accommodate more connections without significantly increasing DIN rail length. Its screw clamp termination system provides dependable conductor retention, while the polyamide 6.6 housing offers durable electrical insulation for demanding industrial environments.
With an IEC rated current of 32 A and an IEC rated voltage of 800 V AC, the M4/6.D1.1 is suitable for industrial signal and control circuits. It accepts flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.2–4 mm², while compatibility with G32, TH35-7.5 and TH35-15 DIN rails provides flexible installation in electrical cabinets.
Double-level terminal blocks allow multiple conductor connections to be arranged vertically within a compact DIN rail footprint. This configuration helps increase wiring density and makes efficient use of available cabinet space, particularly in automation and control panels containing large numbers of signal circuits.
The M4/6.D1.1 combines this space-efficient format with proven screw clamp termination technology. Its two-level design, wide operating temperature range and compatibility with common industrial DIN rails make it suitable for organised, maintainable wiring throughout machinery, process control and industrial automation systems.
