Weidmüller 1003580000 SL-SMT 3.50/09/135F 3.2SN BK BX Guide
The Weidmüller 1003580000 SL-SMT 3.50/09/135F 3.2SN BK BX is a 9-pole PCB male header for designers who need an expanded compact interface without leaving the disciplined structure of a pluggable connector family. As a Weidmüller 1003580000 PCB plug-in connector male header, it is suited to professional electronics where board density, interface clarity, and service-friendly design are all part of the engineering brief.
Product definition and connector format
This part is specified as a flanged male header with THT/THR solder connection, a 3.50 mm pitch, 9 poles, and 135-degree orientation. The solder pin length is 3.2 mm, the finish is tinned, the housing is black, and the part is supplied in a box. The official product data lists IEC 320 V / 15 A and UL 300 V / 10 A.
Nine poles bring the connector into a very practical range for richer compact circuits. It can support grouped control functions, signal arrays, and other board-level interfaces that need more capacity than the smaller variants in the same family.
Why this 9-pole header is useful
The Weidmüller SL-SMT 3.50/09/135F 3.2SN BK BX male header is valuable in designs where connection organisation must scale with product functionality. Instead of adding multiple smaller connectors and increasing complexity, one 9-pole interface can keep the design more coherent. That often benefits assembly, diagnostics, and field servicing.
In compact industrial products, a connector is often one of the most visible signs of design quality. A well-matched pluggable interface supports a cleaner mechanical layout and a more understandable system architecture.
Mechanical design value
The flange and THT/THR solder connection give the connector a reliable mechanical foundation on the PCB. That matters for products exposed to installation handling, operational stress, or extended service life. The 135-degree orientation also improves the designer’s ability to control how the mating side approaches the board and how wiring aligns within the enclosure.
Those factors are not secondary. In many real products, connector angle and board anchoring influence usability just as much as the electrical specification. That is why the Weidmüller 1003580000 SL-SMT 3.50/09/135F 3.2SN BK BX product type should be evaluated as a system component, not merely a line item.
Typical applications
This connector can be relevant in compact automation systems, distributed I/O electronics, controller subassemblies, embedded industrial devices, building control modules, and instrumentation hardware. The 9-pole layout offers enough interface capacity for more advanced compact boards while still staying within a manageable footprint.

Weidmüller 1003580000 FAQ
What is Weidmüller 1003580000?
It is a 9-pole PCB plug-in connector male header with flange, 3.50 mm pitch, 135-degree orientation, and THT/THR solder connection.
Why choose a 9-pole compact connector?
A 9-pole connector helps group a larger number of board connections into one compact and clearly defined interface, which can improve organisation and reduce connector clutter.
Does the flange improve usability?
Yes. Depending on the application, the flange can support more controlled mounting and more stable connector positioning during integration and use.
What is the advantage of staying within the same connector family?
Using related products from one family can simplify design standardisation, documentation, and future product scaling across different pole counts.
Is this connector only for compact devices?
It is especially useful in compact devices, but its relevance depends on the board architecture and application requirements rather than size alone.
What should be confirmed before final specification?
Engineers should confirm mating compatibility, PCB footprint accuracy, insulation requirements in the finished product, assembly suitability, and enclosure access around the 135-degree connector orientation.
