Weidmüller 1006640000 Male Header Technical Guide
The Weidmüller 1006640000 male header, identified as SL 5.00/03/180B 3.2SN GN BX, is a board-side connector component designed for pluggable PCB systems. Unlike a female plug that terminates the field wiring, this product acts as the male header on the PCB, providing the mating interface for compatible plug connectors.
That makes the product particularly relevant to users looking for a Weidmüller 1006640000 male header, 3-pole PCB header connector, or Weidmüller SL 5.00/03/180B for board-level integration.
Published technical characteristics
Weidmüller describes this product as a PCB plug-in connector, male header with dovetails for fixing blocks and THT solder connection. It has a 5.00 mm pitch, 3 poles, a 180° design, and a 3.2 mm solder pin length. The contact surface is tinned, and the housing color is listed as pale green. Electrical data on the product page shows IEC: 400 V / 18 A and UL: 300 V / 15 A. A notable current product-page detail is that this code is marked discontinued, with a listed last order date of 31 August 2025. :contentReference[oaicite:9]{index=9}
Why a male header matters in PCB connection systems
In a pluggable connector architecture, the male header is the fixed board-side anchor. It determines how the removable plug interfaces with the PCB and plays a major role in mechanical stability, mating reliability, and solder-side robustness. The Weidmüller 1006640000 male header is intended to deliver that board-side consistency in systems using pluggable terminal technology.
Its THT construction is especially relevant because through-hole termination is often preferred in industrial electronics where stronger board retention is desirable. Compared with lighter surface-mount approaches, THT headers can offer better mechanical confidence in products exposed to repeated plugging cycles or more demanding handling conditions.
Why the 3-pole version is still useful
A 3-pole male header is often exactly what a design calls for. Small power groups, compact control circuits, and auxiliary interfaces do not always require a larger connector footprint. Choosing the right pole count can improve board layout efficiency without sacrificing serviceability.
The Weidmüller SL 5.00/03/180B 3.2SN GN BX male header therefore fits applications where the mating plug needs to remain compact but still sit within a professional, industrial connector family.
Important lifecycle consideration
One of the most important details for engineers and sourcing teams is the product status. Recent product references indicate that this code is discontinued. That does not make the technical information irrelevant. On the contrary, it makes proper identification even more important for maintenance, replacement planning, documentation updates, and legacy equipment support.
If an existing design already uses this header, understanding the exact specification remains valuable for compatibility reviews and transition planning.
FAQ
What is Weidmüller 1006640000?
It is a 3-pole male header for PCB plug-in connector systems. It is the board-side component intended to mate with compatible plug connectors in a removable interconnection setup.
Why is THT solder connection important here?
THT, or through-hole technology, generally provides stronger mechanical retention on the PCB. That can be advantageous in industrial products where connectors may be plugged and unplugged multiple times over their service life.
What are the key ratings of this male header?
The published product data lists IEC values of 400 V and 18 A, and UL values of 300 V and 15 A. The product uses a 5.00 mm pitch and has 3 poles with a 3.2 mm solder pin length.
Is this product still active?
Recent product-page information indicates that it is discontinued and lists 31 August 2025 as the last order date. That makes it especially important for legacy design tracking and replacement assessments.
Who would still need information about a discontinued male header?
Engineers working on installed equipment, service teams maintaining older systems, and procurement teams reviewing compatibility for legacy assemblies may all need precise information about discontinued parts like this one.
