Weidmüller 1003570000 SL-SMT 3.50/08/135F 3.2SN BK BX Guide
The Weidmüller 1003570000 SL-SMT 3.50/08/135F 3.2SN BK BX is an 8-pole PCB male header that serves designers who need a denser pluggable board interface while staying within a compact connector family. As a Weidmüller 1003570000 PCB plug-in connector male header, it supports organised board connectivity in industrial and technical devices where both connection count and layout efficiency have become important design priorities.
Main product characteristics
This connector is specified as a flanged male header with THT/THR solder connection, 3.50 mm pitch, 8 poles, and a 135-degree orientation. It uses a 3.2 mm solder pin length, tinned contact surfaces, black housing, and box packaging. The official ratings for this part are IEC 320 V / 15 A and UL 300 V / 10 A.
An 8-pole layout gives engineers meaningful interface density without pushing directly into much larger connection systems. That can be highly useful in compact electronics where every millimetre of PCB edge space must justify itself.
Why the 8-pole version stands out
The Weidmüller SL-SMT 3.50/08/135F 3.2SN BK BX male header is a good fit when multiple control, signal, or low-voltage connections need to be grouped in one clear interface. That approach often simplifies assembly, reduces connector variety on the board, and improves the overall visual logic of the product.
In industrial electronics, a tidy connection strategy has long-term benefits. It can shorten troubleshooting time, reduce wiring mistakes, and make documentation easier for engineering teams and service personnel alike.
Layout and integration considerations
The 135-degree format is more than a geometric detail. It has a real effect on how the connector behaves within the product. It influences clearance, mating access, and cable approach direction. In compact housings or equipment with tightly packed components, that design angle can improve usability and reduce integration friction.
The THT/THR soldering concept also supports a stronger board connection than many lighter-duty alternatives. That is particularly relevant for devices expected to remain mechanically stable over long lifecycles or in demanding installation environments.
Application context
The Weidmüller 1003570000 SL-SMT 3.50/08/135F 3.2SN BK BX product type can be relevant in industrial controller boards, compact automation hardware, interface electronics, communication modules, and smart control products. Eight poles are often enough to support moderately complex grouped functions while still preserving a compact connector approach.

Weidmüller 1003570000 FAQ
What is Weidmüller 1003570000?
It is an 8-pole PCB plug-in connector male header with flange, 3.50 mm pitch, THT/THR solder connection, and 135-degree orientation.
When is an 8-pole header a good choice?
It is a strong choice when a design needs several related connections grouped in one compact interface rather than spread across multiple smaller headers.
What does the 3.50 mm pitch contribute?
It helps keep the connector compact while still preserving a practical spacing level for professional PCB connection design.
Why does soldering method matter?
The THT/THR concept contributes to secure mechanical anchoring on the board, which is valuable for durability and handling stability.
Should the angle be considered during enclosure design?
Absolutely. The connector angle affects approach direction, clearance, and service access, so it should always be reviewed with the enclosure layout.
Can this part support system standardisation?
Yes. It belongs to a connector family with related variants, which can help maintain consistency across multiple boards and product generations.
