Weidmüller 1001340000 S2L-SMT 3.50/04/90LF Gold Header Guide
The Weidmüller 1001340000 S2L-SMT 3.50/04/90LF male header is a compact PCB connection component designed for pluggable board systems where stable mating performance, organized board layout, and practical assembly behavior are important. In industrial electronics, connector selection is rarely based on dimensions alone. Engineers also evaluate plating, orientation, serviceability, and manufacturing fit. This product earns attention because it combines those design priorities in a compact package.
This Weidmüller S2L-SMT 3.50/04/90LF 3.5AU BK BX version is associated with a 4-pole arrangement, 3.50 mm pitch, right-angle layout, black housing, and gold-plated contact design. The gold-plated detail is especially relevant in environments where designers want enhanced contact behavior in signal-oriented or precision-focused board connections. While not every application requires that finish, many engineers deliberately choose it where stable low-level contact performance matters.
Weidmüller 1001340000 What Makes This Header Distinct
The Weidmüller 1001340000 gold male header is built for PCB mounting in a pluggable connection system. The 90-degree orientation supports lateral mating, which is useful in low-profile products and compact enclosures. Because the header sits on the board and receives the mating plug, it becomes a critical structural point in the design. Reliable geometry here supports better handling during assembly, maintenance, and field service.
Its 3.50 mm pitch makes it an efficient choice for compact electronics that still need a connector large enough for convenient real-world use. That pitch continues to be favored in industrial controls, interface technology, building automation, and embedded electronics with structured signal distribution.
Why Gold-Plated Contacts Matter in Some Designs
The Weidmüller 1001340000 S2L-SMT 3.50/04/90LF gold header stands apart from tin-based variants because gold-plated contact systems are often selected for applications that emphasize dependable signal integrity, consistent mating quality, and reduced contact variability over repeated use. In instrumentation, communication electronics, and refined control interfaces, that can be a worthwhile design choice.
This does not automatically mean every application needs gold-plated connectors. Instead, it means the product offers a targeted option for engineers who want that level of contact finish within a known Weidmüller pluggable PCB platform.
Weidmüller 1001340000 Advantages of the 90-Degree Layout
Right-angle headers help direct the connector interface toward the side of the assembly. This can preserve vertical clearance, simplify side-access wiring, and improve internal cable flow in compact housings. In devices mounted close to cabinet walls or stacked with other boards, that orientation can be far easier to work with than a straight mating arrangement.
As a result, the Weidmüller S2L-SMT 3.50/04/90LF male header is a practical option for compact control devices, smart building modules, communication hardware, alarm systems, interface cards, and distributed electronic assemblies.
Design Perspective for Engineers
Good connector selection improves manufacturability, maintenance behavior, and end-user confidence. The Weidmüller 1001340000 supports a pluggable architecture that separates board assembly from field wiring while keeping the connector footprint compact. That is valuable in products designed for series production, modular service, or field replacement.
Engineers should still evaluate the full system context, including mating pair selection, enclosure size, maintenance access, conductor management, and overall board mechanics. When those factors align well, connectors like this contribute to a cleaner and more dependable product design.

Weidmüller 1001340000 FAQ
What type of connector is Weidmüller 1001340000?
It is a board-mounted male header for pluggable PCB connection systems, designed in a 4-pole, 3.50 mm pitch format.
Why is gold plating relevant?
Gold plating is often chosen where engineers want highly consistent contact behavior, especially in signal-focused or precision-oriented board interfaces.
What is the benefit of the 90-degree version?
A right-angle connector can save vertical space, guide wiring toward the side of the product, and support neater enclosure integration.
Where is this header commonly useful?
It is well suited to compact control electronics, communication devices, instrumentation, interface boards, and other modular PCB systems.
Is 3.50 mm pitch a standard industrial size?
It is a very common and practical format in compact pluggable PCB connectivity, especially for signal and control applications.
Why do designers choose pluggable headers instead of fixed terminals?
Because pluggable systems improve service access, speed up board replacement, and help separate the wiring harness from the PCB during maintenance.
