Weidmüller 1005410000 BCZ 3.81 AH16 BK BX Cover Hood
The Weidmüller 1005410000 BCZ 3.81 AH16 BK BX cover hood is a 16-pole black accessory for PCB plug-in connectors in the OMNIMATE Signal BC/SC 3.81 family. As a protective hood for the connector area, it is built for applications that require a higher pole count while still maintaining compact PCB-level signal interfacing and clean mechanical integration.
What Makes This 16-Pole Version Relevant
As pole count increases, maintaining order and compatibility across the connector area becomes more important. A 16-pole hood supports connector assemblies where more signals need to be grouped in a single interface, but where the design still relies on pluggable PCB architecture rather than larger terminal-based alternatives. The Weidmüller 1005410000 is therefore especially relevant for modular device platforms, communication interfaces, process electronics, and machine control systems that use medium-density board connectors.
The product belongs to the BC/SC 3.81 series, a connector family built around a 3.81 mm pitch. This pitch is widely used where compact signal connection and practical assembly spacing need to coexist. A hood that is precisely matched to this system helps ensure the accessory does not become the weak point in an otherwise carefully engineered connection concept.
Technical Profile
Official Weidmüller data identifies the BCZ 3.81 AH16 BK BX as a cover hood for protecting the PCB plug-in connector. It is specified for 16 poles, with a one-row layout and a 3.81 mm pitch within the OMNIMATE Signal series. The tightening torque for the cover screw is listed as 0.4 to 0.5 Nm. The net weight is approximately 10.5 g, which reflects the larger pole count while keeping the component suitable for structured PCB assembly.
The product page also lists RoHS conformity and environmental compliance data indicating no SVHC above 0.1 wt%. For industrial OEMs, these details matter because accessories are not exempt from compliance-driven product documentation. A complete bill of materials should include accurate accessory references, especially when the connector ecosystem is tightly defined.
Practical Design Benefits
Choosing the correct 16-pole hood helps maintain connector integrity in devices where serviceability and repeatable installation are important. This is relevant in automation electronics, distributed controls, HVAC interfaces, embedded industrial communication modules, and multi-signal monitoring devices. The point is not merely to “cover” the connector but to complete the assembly in a controlled and series-consistent way.
That is why technical identification matters. Search phrases such as Weidmüller 1005410000 cover hood, BCZ 3.81 AH16 BK BX hood, and Weidmüller 16-pole PCB connector accessory are the kind of exact references engineers and procurement teams rely on when comparing specifications and confirming compatibility.
Lifecycle and Specification Accuracy
Because connector accessories often look simple, they are sometimes documented loosely. That can lead to mismatches later. The better approach is to retain the full reference, including brand, code, series, pole count, and product type. In this case, the complete identifier Weidmüller 1005410000 BCZ 3.81 AH16 BK BX cover hood captures the exact technical context needed for accurate sourcing and product support.
