TE Connectivity 1SNA020850R0300 BFMSUBD-25M-2E is an Interfast single-wire PLC connecting interface with a 25-pole male Sub-D connector and DIN rail mounting for industrial automation and control-panel wiring.
Why Choose the TE Connectivity BFMSUBD-25M-2E PLC Interface?
The TE Connectivity 1SNA020850R0300, also designated BFMSUBD-25M-2E, is a compact single-wire PLC connecting interface designed to simplify signal wiring between industrial controllers and field-level connections. Part of the TE Connectivity / Entrelec Interfast interface range, it combines terminal connections with a multipole connector to provide an organised interface point within industrial control panels.
The BFMSUBD-25M-2E is equipped with a 25-pole male Sub-D connector, enabling multiple control signals to be routed through one compact interface rather than relying entirely on individual point-to-point wiring. This arrangement can reduce wiring complexity, improve panel organisation and make connection and maintenance tasks more efficient for machine builders and automation engineers.
Designed for DIN rail mounting, the interface uses pluggable / screw-clamp connections for integration with control wiring. Its passive connecting-interface design makes it suitable for PLC I/O breakout, signal distribution and other industrial automation applications where a reliable transition between multipole and individual wiring is required.

Efficient PLC Signal Wiring for Industrial Automation
PLC interface modules provide a convenient transition between high-density controller connectors and individual field wiring. By grouping multiple signal paths through a single multipole connection, the TE Connectivity BFMSUBD-25M-2E can simplify cabinet wiring and help create a cleaner, more structured control system than conventional point-to-point connections.
The combination of a 25-pole male Sub-D connector, individual terminal connections and DIN rail mounting makes this Interfast interface particularly useful for control cabinet construction and machine automation. It allows system integrators and panel builders to organise signal distribution efficiently while retaining accessible field-side connection points for installation, testing and maintenance.
