Weidmüller 1004230000 SL-SMT 5.08HC/18/90V 3.2AU BK BX SO ABB PCB Header
The Weidmüller 1004230000 SL-SMT 5.08HC/18/90V 3.2AU BK BX SO ABB is an 18-pole male PCB header developed for pluggable board connections that demand a more powerful electrical profile than smaller signal-oriented connector classes. It belongs to the OMNIMATE Signal BL/SL 5.08 family and stands out through its 5.08 mm pitch, 90° outlet, high-current orientation, and gold-plated contact configuration. In practical engineering terms, this is the kind of connector that gets attention when designers need both structured pluggable connectivity and stronger electrical capability on the board.
What makes this header different
Compared with more compact 3.50 mm pitch signal connectors, the Weidmüller 1004230000 SL-SMT 5.08HC/18/90V 3.2AU BK BX SO ABB PCB header moves into a more robust connection class. The 5.08 mm pitch gives the design more spacing and a stronger platform for higher current handling. With 18 poles, it still offers substantial circuit capacity, making it a compelling choice for devices that combine control, distribution, and structured board-level power or higher-load interconnection tasks.
The 90° outlet also plays a major role. In many assemblies, a right-angle connector is the most sensible way to align wiring or mating connector paths with the enclosure wall, PCB orientation, or service access path. This helps the connector integrate naturally into practical equipment design rather than forcing an awkward routing solution.
Technical characteristics of the Weidmüller 1004230000
This product is an open-side male header with THT/THR solder connection, 5.08 mm pitch, 18 poles, and a 3.2 mm solder pin length. One especially notable point is the Au, or gold-plated, contact finish. Gold-plated contact surfaces are often selected where stable long-term contact behavior, corrosion resistance, and high-quality signal or power transfer characteristics are priorities. In the right application, that can be an important differentiator.
The electrical reference values are listed at IEC 400 V / 27.5 A and UL 300 V / 18.5 A. These figures place the connector in a clearly stronger performance category than many lower-pitch signal headers. While final use still depends on temperature, pole loading, creepage and clearance, and the full device architecture, the published values make the intended positioning of this connector very clear.
Why an 18-pole 5.08 mm high-current header is valuable
A connector like this serves applications where one board interface must handle multiple lines in a robust, organized format. The 18-pole count allows a significant number of circuits to be grouped together, which can simplify power distribution logic, reduce the need for several smaller connectors, and create a cleaner interface on the board. In machine electronics, industrial drives, controller hardware, power interface units, and specialized OEM devices, that kind of structure can be a major advantage.
The exact search phrase Weidmüller 1004230000 SL-SMT 5.08HC/18/90V 3.2AU BK BX SO ABB PCB header is therefore highly meaningful. Every element of the description matters: brand, product code, pitch, pole count, angle, plating, and connector type all influence compatibility and design suitability.
Material and mounting benefits
This header uses THT/THR mounting, which is often preferred where board retention and mechanical confidence are important. Through-hole based connector mounting can be especially attractive in higher-load or more demanding industrial electronics, where a more substantial mechanical interface is often desirable. The black housing supports a standard industrial appearance, while the open-side form and right-angle exit can help the connector fit efficiently within the intended board and enclosure arrangement.
Because the product belongs to an established Weidmüller connector family, it also benefits from the familiarity and structured design logic engineers often look for when standardizing interconnect solutions across multiple products.
Where this connector is commonly relevant
The Weidmüller 1004230000 SL-SMT 5.08HC/18/90V 3.2AU BK BX SO ABB PCB header is highly relevant for industrial controller boards, power interface electronics, drive-related systems, machine modules, robust communication hardware, and specialized PCB assemblies where both pole count and electrical performance matter. It is not simply a generic board connector. It is a deliberate solution for designers who need a right-angle, pluggable, higher-capacity header in a reliable industrial format.

Weidmüller 1004230000 FAQ
What type of connector is the Weidmüller 1004230000?
It is a male PCB header in the OMNIMATE Signal BL/SL 5.08 family, designed with 18 poles, a 90° outlet, and THT/THR solder mounting.
Why is the 5.08 mm pitch important?
The 5.08 mm pitch supports a more robust connection format with greater spacing and a stronger current-handling profile than smaller compact signal connector families.
What does the gold-plated contact finish add?
Gold plating can support stable long-term contact behavior and is often preferred where dependable electrical performance and contact quality are especially important.
Is this connector suitable for higher-load PCB applications?
Yes, within its published reference ratings and the constraints of the final device design. Its IEC and UL values position it above many smaller pitch signal headers.
Why would engineers search specifically for Weidmüller 1004230000 SL-SMT 5.08HC/18/90V 3.2AU BK BX SO ABB PCB header?
Because the exact combination of pitch, pole count, right-angle format, gold-plated contact surface, and Weidmüller family compatibility determines whether it will fit the intended design both mechanically and electrically.
