Weidmüller 1003510000 SL-SMT 3.50/02/135F 3.2SN BK BX Guide
The Weidmüller 1003510000 SL-SMT 3.50/02/135F 3.2SN BK BX is a compact PCB male header developed for applications where space efficiency and predictable mating geometry are essential. As a Weidmüller 1003510000 PCB plug-in connector male header, it is built around a 3.50 mm pitch and a 2-pole layout, making it a practical option for compact signal and low-power board connections in industrial and electronic equipment.
Product structure and format
This version is specified as a flanged male header with THT/THR solder connection. The flange is important because it supports more stable integration in mating arrangements where alignment and retention consistency matter. The connector also uses a 135-degree orientation, which changes how the counterpart approaches the board and can make a noticeable difference in enclosure packaging and cable path management.
In smaller controller boards, communication modules, and sensor electronics, this type of angled connector can improve accessibility while keeping the board design compact. The result is a connection interface that feels deliberate rather than improvised.
Technical details behind the part number
The Weidmüller SL-SMT 3.50/02/135F 3.2SN BK BX male header features a 3.50 mm pitch, 2 poles, 135° design, and a 3.2 mm solder pin length. It is tinned, finished in black, and supplied in box packaging. Official product data lists IEC 320 V / 15 A and UL 300 V / 10 A, which is a strong profile for a compact pluggable PCB connector in its class.
The two-pole format makes this component especially relevant when designers need a simple and clean board interface for a small number of conductors without moving up to a larger connector family. It keeps the footprint lean while preserving the benefits of a structured pluggable system.
Where this connector fits best
The Weidmüller 1003510000 SL-SMT 3.50/02/135F 3.2SN BK BX product type is well suited to compact control electronics, sensor interfaces, building automation modules, compact power electronics, and communication boards. In those environments, designers often need connectors that are small enough for dense layouts but still professional in both soldering concept and mating quality.
A connector like this is also useful when serviceability matters. Pluggable board connectors help reduce time during maintenance or replacement because they allow field-side wiring strategies to be separated from the board itself. That can be a meaningful operational advantage even in relatively small devices.
Why the 135-degree format matters
Engineers sometimes focus only on pole count and electrical values, but connector angle can be just as important. A 135-degree header affects access, cable routing, and clearance planning. In compact housings, that can improve ergonomics and reduce stress on connected conductors. It also helps create more intentional wire exit paths, especially where vertical height is limited or neighbouring components leave little room.

Weidmüller 1003510000 FAQ
What is Weidmüller 1003510000?
It is a 2-pole PCB plug-in connector male header from Weidmüller, built with a 3.50 mm pitch, flange, THT/THR solder connection, and 135-degree orientation.
Why would someone choose a 2-pole male header like this?
A 2-pole version is ideal when only a small number of conductors must be connected and the design needs to stay compact, tidy, and easy to integrate into a small PCB layout.
What does 3.2SN indicate in this product?
It refers to the 3.2 mm solder pin length, which is relevant for board thickness and assembly process considerations.
Is this connector suitable for industrial PCB design?
Yes. Its formal pluggable design, robust soldering concept, and industrial connector family background make it suitable for a wide range of industrial and professional electronics applications.
What should be checked before using it in a design?
Designers should verify the matching counterpart, required creepage and clearance distances in the end application, PCB footprint compatibility, board thickness, and enclosure routing constraints.
Can it support future design scaling?
Yes. One advantage of connector families like this is that designers can often preserve the same general connection concept while moving to higher pole-count variants when a product platform expands.
