1sna020851r2000 – bfmsubd-25f-2e interface module
TE Connectivity 1SNA020851R2000 BFMSUBD-25F-2E is an Interfast single-wire connecting interface module with a 25-pole female Sub-D connector, screw-clamp connections and DIN rail mounting for PLC and industrial automation wiring.
Why Choose the TE Connectivity BFMSUBD-25F-2E Interface Module?
The TE Connectivity 1SNA020851R2000, also designated BFMSUBD-25F-2E, is a compact single-wire connecting interface module designed to simplify signal connections between programmable logic controllers (PLCs), automation equipment and field wiring. Part of the established TE Connectivity / Entrelec Interfast range, it provides an efficient transition between a high-density Sub-D connection and individual screw-clamp wiring inside industrial control panels.
The BFMSUBD-25F-2E incorporates a 25-pole female Sub-D connector, allowing multiple control and signal circuits to be connected through a single multipole interface. This helps reduce conventional point-to-point wiring, improves cabinet organisation and provides a convenient connection point for machine builders, panel manufacturers and industrial automation engineers.
Designed for DIN rail mounting, the interface combines a compact form factor with pluggable screw-clamp connections for practical installation and maintenance. Its passive single-wire architecture makes it particularly suitable for PLC I/O breakout, signal distribution and control-panel applications where reliable and clearly organised connectivity is required.

Efficient Signal Interfacing for Industrial Automation
Connecting interfaces such as the TE Connectivity BFMSUBD-25F-2E provide a convenient transition between multipole PLC connections and individual control-panel conductors. By routing numerous signals through a single 25-pole Sub-D connector, the module can significantly simplify cabinet wiring compared with wiring every signal directly between the controller and terminal field.
The combination of a female Sub-D connector, screw-clamp terminals and DIN rail mounting makes the BFMSUBD-25F-2E particularly useful for machine building and automation cabinet construction. Its accessible terminal arrangement supports installation, testing and maintenance while helping panel builders maintain clean and structured signal wiring.
Typical Applications
- PLC input and output signal interfacing.
- Industrial automation control panels.
- Factory automation and production machinery.
- Machine building and OEM control systems.
- Process control and instrumentation panels.
- Signal breakout and distribution applications.
- Conveyor and material handling control systems.
- Control cabinets using 25-pole Sub-D connections.
