Weidmüller 1005400000 BCZ 3.81 AH15 BK BX Cover Hood
The Weidmüller 1005400000 BCZ 3.81 AH15 BK BX cover hood is a 15-pole black accessory for PCB plug-in connectors in the OMNIMATE Signal BC/SC 3.81 family. This product is designed to protect and complement compatible connector assemblies, making it relevant for industrial electronics environments where signal connections must remain organized, serviceable, and properly matched to their mechanical interface.
Product Function in PCB Connector Design
A dedicated cover hood helps turn a connector from a simple electrical interface into a more complete mechanical connection system. In practical use, that means better alignment with the intended assembly structure, cleaner handling during installation, and improved consistency in service documentation. The Weidmüller BCZ 3.81 AH15 BK BX is intended specifically for a 15-pole arrangement, which makes it a focused solution for applications that require this pole count in a compact board-level form factor.
Because the product belongs to the OMNIMATE Signal BC/SC 3.81 series, it fits into a connector platform widely used for signal transmission on PCBs. The 3.81 mm pitch is often selected for a balanced combination of compactness and functional accessibility. For designers of automation electronics and control interfaces, choosing series-matched accessories can reduce integration friction later in the product lifecycle.
Technical Specification Summary
Official product information identifies this part as a black cover hood accessory with 15 poles. It belongs to the BC/SC 3.81 family and uses a one-row configuration. The net weight is approximately 10.2 g. The tightening torque for the cover screw is specified at 0.4 to 0.5 Nm. Product classification information also identifies it as a cover hood for protecting the PCB plug-in connector.
The product page further notes that this item will soon be unavailable. That is valuable lifecycle information for engineers, purchasing teams, and service planners. When a project depends on precise accessory matching, even a seemingly small hood part should be documented early to support long-term maintenance and approved-part traceability.
Design and Application Considerations
The value of a product like the Weidmüller 1005400000 is often clearest in real device design. On a crowded control board, connector accessories need to support not only fit but also repeatable assembly processes. A 15-pole hood is especially relevant in applications that fall between standard low-pole signal connectors and broader multi-contact interfaces.
That makes this part suitable for interface modules, machine controls, energy management electronics, compact I/O devices, communication interfaces, and industrial instrumentation. In all of these use cases, exact connector ecosystem matching contributes to better product integrity and fewer surprises during servicing or field replacement.
Search Relevance and Technical Identification
Professionals rarely search only for broad terms such as “PCB hood.” They usually search with exact identifiers, which is why terms such as Weidmüller 1005400000 cover hood, BCZ 3.81 AH15 BK BX cover hood, and Weidmüller 15-pole PCB plug-in connector hood are much more useful in technical content and product support documentation. These phrases reflect real-world engineering search behavior and improve clarity for distributors, technicians, and documentation teams.
