Weidmüller 1005330000 BCZ 3.81 AH08 BK BX for 8-Pole Board-to-Wire Connector Systems
The Weidmüller 1005330000 BCZ 3.81 AH08 BK BX cover hood is aimed at PCB connector applications where an eight-position plug-in interface needs a matching protective accessory. In connector system planning, accessory compatibility is part of overall design quality. A hood that aligns correctly with the connector family can support cleaner assembly, safer handling, and a more complete mechanical finish.
Official product data identifies the Weidmüller BCZ 3.81 AH08 BK BX hood as a black accessory hood for PCB plug-in connectors in the OMNIMATE Signal BC/SC 3.81 series. This model is designed for 8 poles, uses the family 3.81 mm pitch, comes in box packaging, has a cover screw tightening torque of 0.4 to 0.5 Nm, and weighs about 6.1 g. The associated family data also places it within a one-row connector system.
Why the 8-Pole Format Has Design Significance
The Weidmüller 1005330000 BCZ 3.81 AH08 BK BX 8-pole hood is specifically relevant where a connector interface carries more positions and therefore requires a wider, properly matched housing accessory. In multi-pole PCB connectors, even small dimensional mismatches can undermine the quality of the final assembly. A pole-specific hood helps avoid that problem by aligning with the intended connector footprint.
That precision becomes especially useful in modular electronics where connector assemblies may be repeated across multiple product variants or board layouts.
Position Within the BC/SC 3.81 Series
The BC/SC 3.81 family is part of the OMNIMATE Signal portfolio, which is focused on structured PCB connectivity. The Weidmüller BCZ 3.81 AH08 BK BX PCB hood fits into that architecture as a dedicated accessory, not as a universal add-on. That gives designers a more predictable fit and simplifies the process of creating standardized board-to-wire interfaces across product lines.
The defined tightening torque range of 0.4 to 0.5 Nm again signals that the part is meant to be assembled with controlled mechanical values. That is important wherever production documentation and repeatability are part of the engineering process.
Mechanical and Handling Benefits
The Weidmüller 1005330000 BCZ 3.81 AH08 BK BX connector hood helps protect the connector area, improve the feel of the assembled interface, and support clearer handling during installation and service. These may sound like small improvements, but in real products they contribute to lower handling risk and a more robust product experience.
In dense electronic assemblies, connector-related clarity is important. When the connection point looks and feels properly structured, maintenance becomes more straightforward and product quality is easier to trust.
Typical Use Cases
A Weidmüller 1005330000 BCZ 3.81 AH08 BK BX hood is suitable for automation electronics, compact industrial controllers, I/O modules, signal interface boards, building automation products, and custom PCB-based devices that use 8-pole BC/SC 3.81 pluggable connectors.
