Weidmüller 1003640000 SL-SMT 3.50/14/135F 3.2SN BK BX Guide
The Weidmüller 1003640000 SL-SMT 3.50/14/135F 3.2SN BK BX is a 14-pole PCB male header intended for compact but more capable pluggable board interfaces. As a Weidmüller 1003640000 PCB plug-in connector male header, it is a practical option for electronics designers working on automation devices, smart control boards, instrumentation assemblies, and technical products that require higher connection density in a disciplined format.
As products become more connected and feature-rich, the value of a clean connector strategy increases. A poorly chosen connection interface can create routing issues, waste board space, and complicate service access. The Weidmüller 1003640000 SL-SMT 3.50/14/135F 3.2SN BK BX male header addresses this challenge by offering expanded pole count within a compact footprint and an angled format that supports better integration.
How the product is built
This connector is a flanged male header with THT/THR solder connection. That means it is built not only for electrical function but also for physical resilience on the board. The flange can support more consistent alignment, while the soldering format helps the connector withstand insertion and handling forces over the product lifecycle.
The 135-degree geometry is equally important. In compact housings, the wrong connector angle can make assembly difficult or create awkward cable paths. With a 135-degree design, engineers have more control over how the mating part enters the board area and how the connected wiring behaves inside the enclosure.
Technical features
The official family profile for the Weidmüller SL-SMT 3.50/14/135F 3.2SN BK BX PCB connector includes 3.50 mm pitch, 14 poles, 3.2 mm solder pin length, tinned contacts, black housing, and box packaging. Electrical ratings within this series are IEC 320 V / 15 A and UL 300 V / 10 A. That gives the connector a strong position in professional board-level connectivity.
Fourteen poles offer enough capacity for broader grouped interfaces while still fitting within a compact connector family. This can reduce the need for extra board connectors and help create a more intuitive device layout.
Best-fit applications
The Weidmüller 1003640000 PCB male header is suitable for controller electronics, distributed automation modules, communication subassemblies, interface cards, and advanced building control devices. In these systems, one well-organised multi-pole connection point often delivers better usability than several small and fragmented interfaces.
For maintenance teams, that can translate into clearer diagnostics and easier field replacement. For design teams, it can mean a more scalable architecture for future revisions.
Long-term engineering value
A connector family like this supports product continuity. Teams can keep the same pitch, connection logic, and mating philosophy while moving between different pole counts across a product range. That reduces redesign effort and helps preserve consistency in documentation, testing, and procurement.

Weidmüller 1003640000 FAQ
What is Weidmüller 1003640000?
It is a 14-pole PCB plug-in connector male header with flange, 3.50 mm pitch, THT/THR solder connection, and 135-degree orientation.
Why would 14 poles be useful?
It provides more grouped interface capacity for richer compact devices without forcing a move to a larger connector system.
Is the connector suitable for industrial PCB design?
Yes. Its structure and ratings make it suitable for many industrial and professional electronics applications.
What is the value of the angled design?
The angled design can improve cable routing and enclosure integration, especially where board space and access are limited.
How does the flange help?
The flange supports more controlled connector positioning and can improve interface consistency in practical assembly conditions.
What should engineers check before using it?
They should check mating compatibility, board footprint, insulation distances, enclosure clearance, and service access around the connector position.
