The TE Connectivity / Entrelec BFMHE-10/20-2E, part number 1SNA020840R0100, is an industrial double-deck single-wire connecting interface for an HE10/20 connector. Designed for PLC, I/O and automation wiring, it provides an organised transition between a high-density 20-way HE10 connection and individual screw-clamp field wiring inside electrical control panels.
The BFMHE-10/20-2E combines pluggable and screw-clamp connection technologies in a compact interface module. Its double-deck architecture helps organise multiple signal connections while reducing conventional point-to-point wiring, making installation, identification, testing and maintenance easier in industrial automation cabinets.
Measuring approximately 50 × 56 × 57.5 mm (H × W × D), the module provides a space-efficient solution for high-density signal interfacing. It mounts on standard TH35-7.5 or TH35-15 DIN rails in accordance with IEC 60715 and accepts stranded conductors up to 14 AWG under UL/CSA specifications.
Multi-way HE10 connectors allow numerous control signals to be carried through a compact connection, but industrial field devices typically require accessible individual terminals. A dedicated connecting interface provides an efficient bridge between these two wiring formats, helping reduce manual point-to-point connections and create a more organised panel layout.
The BFMHE-10/20-2E converts the HE10/20 interface into accessible screw-clamp connections within a compact double-deck module. This arrangement supports efficient installation and troubleshooting while providing the secure conductor termination required in industrial PLC, machine control and automation applications.
