The TE Connectivity 1SNA115541R1100, manufacturer designation D2.5/6.DA, is a compact triple-deck screw clamp feed-through terminal block designed for high-density signal wiring in industrial control panels, machinery and automation systems. As part of the established TE Connectivity ENTRELEC SNA terminal block series, it provides three independent feed-through circuits within a single 6 mm-wide terminal body.
This three-level design enables engineers to connect multiple signal conductors while using significantly less DIN rail space than separate single-level terminals. The D2.5/6.DA is particularly well suited to three-wire sensor and actuator connections, making it an efficient choice for PLC cabinets, machine control systems and process automation installations.
With an IEC current rating of 22 A, an operating voltage of 380 V AC and support for flexible conductors up to 2.5 mm², the 1SNA115541R1100 combines compact dimensions with dependable electrical performance. Its screw clamp terminals, polyamide 6.6 housing and compatibility with standard TH35 DIN rails provide a robust solution for demanding industrial wiring applications.
Triple-deck terminal blocks such as the TE Connectivity D2.5/6.DA provide multiple independent electrical connections within the footprint of a single terminal. By arranging three feed-through circuits vertically, the terminal helps reduce DIN rail space requirements while maintaining clear, organised wiring inside control cabinets.
The D2.5/6.DA is especially suitable for three-wire sensors and actuators commonly found in automated machinery and process control systems. Its screw clamp connection technology provides secure conductor retention, while the modular ENTRELEC SNA design allows the terminal to be incorporated into structured DIN rail assemblies alongside other control and signal terminals.
