1sna021059r2600 – bfmsubd-37m-ana

Why Choose the TE Connectivity BFMSUBD-37M-ANA Connecting Interface?

The TE Connectivity BFMSUBD-37M-ANA, manufacturer part number 1SNA021059R2600, is an industrial two-wire connecting interface designed to simplify signal wiring between automation equipment and field connections. Part of the legacy TE Connectivity / Entrelec DIN terminal block range, it combines a 37-pole male SUB-D connector with screw-clamp field connections in a rail-mounted interface module.

The BFMSUBD-37M-ANA provides a structured transition between multi-pole control cabling and individual panel conductors. Its 37-pole male SUB-D interface allows numerous control and signal circuits to be routed through one connector, helping reduce repetitive point-to-point wiring and providing a more organised interface for PLC, machine-control and instrumentation systems.

Measuring approximately 197 × 104 × 69 mm, the 1SNA021059R2600 uses pluggable-to-screw-clamp connectivity and is designed for installation on a G32 mounting rail in accordance with IEC 60715. Its industrial construction and high-density connection format make it well suited to control cabinets requiring structured, accessible multi-signal wiring.

Efficient 37-Pole SUB-D Wiring for Automation Systems

Multi-pole connecting interfaces provide an efficient transition between control equipment and individually terminated field conductors. Instead of routing a large number of separate wires directly between devices, multiple signals can be carried through a SUB-D cable and distributed through an accessible screw-clamp interface inside the control cabinet.

The TE Connectivity BFMSUBD-37M-ANA combines a 37-pole male SUB-D connection with a two-wire interface and screw-clamp termination. This configuration helps panel builders create organised, serviceable signal connections for PLCs, machinery, process-control equipment and other industrial automation systems.

Typical Applications

• PLC input and output interface wiring.
• Industrial control panels and electrical cabinets.
• Machine-building and OEM automation systems.
• Process-control and instrumentation equipment.
• 37-pole SUB-D control and signal connections.
• Factory automation and production machinery.
• High-density industrial signal distribution systems.
