Weidmüller 1001310000 S2L-SMT 3.50/04/180LF Technical Guide
The Weidmüller 1001310000 S2L-SMT 3.50/04/180LF male header is a practical PCB connection component for engineers who need a compact board interface with straight mating geometry and consistent connector handling. In electronics design, small differences in orientation and pin length can have a major impact on enclosure architecture, wire routing, and the overall usability of the finished device. This product addresses exactly that level of detail.
As a Weidmüller S2L-SMT 3.50/04/180LF header, it combines a 3.50 mm pitch with a 4-pole format and a 180-degree orientation. That straight interface is especially useful when the cable path needs to follow the plane of the board or when engineers want a cleaner, more linear connector arrangement. In many control modules, sensor boards, and communication units, this can help simplify harness planning and keep the product footprint disciplined.
Key Product Characteristics
The Weidmüller 1001310000 male header is associated with a black housing, box packaging, and a 3.5 mm solder pin length. It functions as the board-side element in a pluggable PCB connection system, providing the mating interface for a compatible plug. This style is widely used in industrial electronics because it helps separate the PCB assembly from field wiring without sacrificing structure.
That distinction is valuable during installation and maintenance. Instead of reworking every conductor at the board level, technicians can disconnect the plug side, service the board, and reconnect the assembly more efficiently. In systems where uptime matters, that workflow improvement is meaningful.
Why Straight 180-Degree Headers Are Chosen
The Weidmüller S2L-SMT 3.50/04/180LF 3.5SN BK BX stands out because its straight orientation supports direct, in-line mating. This often works well in products with long, narrow housings, front-facing wiring paths, or structured internal cable channels. Compared with a right-angle alternative, a 180-degree header can create a more intuitive front-to-back connection path.
It can also be a good fit where technicians need a clear visual line from plug to wire routing direction. In practical manufacturing and service environments, small ergonomic improvements like that reduce handling mistakes and help make installations feel more controlled.
Typical Application Areas
A Weidmüller 1001310000 S2L-SMT male header can be used in compact automation boards, instrumentation electronics, control interfaces, sensor management hardware, building technology, and modular embedded systems. It is especially relevant in products where pluggability is part of the service concept.
Pluggable systems are not just about convenience. They support modularity. A board can be standardized across different product versions, while the wiring side remains organized and accessible. For manufacturers building scalable electronics platforms, that can be a major design advantage.
How This Connector Supports Better PCB Architecture
Connector choice shapes more than board edges. It affects internal airflow, assembly access, labeling strategy, inspection routines, and long-term service behavior. The Weidmüller 1001310000 S2L-SMT 3.50/04/180LF gives designers a compact straight header format that works well when clarity and controlled board geometry matter.
The 3.50 mm pitch continues to be one of the most useful dimensions in compact PCB connectivity because it allows a good density-to-handling ratio. It is narrow enough to support modern compact boards, yet large enough to remain comfortable for real-world use in industrial products.
