Weidmüller 1005360000 BCZ 3.81 AH11 BK BX for 11-Pole PCB Plug-In Connector Systems
The Weidmüller 1005360000 BCZ 3.81 AH11 BK BX cover hood is designed for one of the larger pole-count variants in this accessory family. In PCB connection design, once a connector reaches eleven positions, the physical interface becomes prominent enough that accessory choice directly affects assembly quality and user handling. A dedicated hood is therefore not a trivial add-on. It is part of how the connector is stabilized and presented within the final device.
Weidmüller lists the Weidmüller BCZ 3.81 AH11 BK BX PCB connector hood as a black accessory hood for the OMNIMATE Signal BC/SC 3.81 series. It is specified for 11 poles, uses a 3.81 mm pitch, is supplied in box packaging, and has a cover screw tightening torque of 0.4 to 0.5 Nm. The published data also gives a net weight of approximately 8.1 g and lists the product as RoHS compliant with no REACH SVHC above 0.1 wt%.
Why an 11-Pole Hood Requires Precision
The Weidmüller 1005360000 BCZ 3.81 AH11 BK BX 11-pole hood highlights why pole count is central to connector accessory selection. As the connector gets wider, exact mechanical matching becomes increasingly important. A hood that is designed for the correct number of poles helps maintain the intended geometry, support the connector area properly, and contribute to a more stable assembly result.
For designers working on compact but feature-rich electronics, that can make a meaningful difference in manufacturing quality and service clarity.
OMNIMATE Signal BC/SC 3.81 Context
The Weidmüller BCZ 3.81 AH11 BK BX connector hood fits into the OMNIMATE Signal BC/SC 3.81 family, which gives it a clear dimensional context. The 3.81 mm pitch and 11-pole format define its compatibility within that ecosystem. This family-based structure helps engineers build connection systems with better predictability, especially when multiple pole counts are used across a product range.
The 0.4 to 0.5 Nm cover screw torque is also part of that structured design logic. It provides a documented assembly target that can be repeated in manufacturing and field service.
Mechanical and Product-Level Benefits
The Weidmüller 1005360000 BCZ 3.81 AH11 BK BX black hood helps protect the plug-in connector interface and supports a more complete mechanical presentation. In larger pole-count connections, those benefits can be especially valuable because the connector area is more exposed and more likely to be handled directly during installation or maintenance.
That makes the hood relevant not just as an accessory but as part of the total usability strategy for the connector system.
Where It Is Most Relevant
A Weidmüller 1005360000 BCZ 3.81 AH11 BK BX cover hood is well suited to industrial control electronics, multi-channel interface boards, larger PCB connection sections, automation modules, and OEM products using 11-pole pluggable connectors in the BC/SC 3.81 series.

Weidmüller 1005360000 FAQ
What is the Weidmüller 1005360000 BCZ 3.81 AH11 BK BX?
It is a black cover hood accessory for an 11-pole PCB plug-in connector in the OMNIMATE Signal BC/SC 3.81 family.
Why is the 11-pole version important?
Because wide connector formats require a precisely matched accessory. An 11-pole hood is designed to fit the corresponding connector width and geometry.
What connector family does this accessory belong to?
It belongs to the OMNIMATE Signal BC/SC 3.81 family, which uses a 3.81 mm pitch and family-specific accessory matching.
What tightening torque is specified?
The recommended tightening torque for the cover screw is 0.4 to 0.5 Nm.
Why would a designer choose a dedicated hood instead of leaving the connector bare?
A dedicated hood improves connector protection, mechanical completeness, and handling quality. It helps the connection interface feel more structured and more serviceable.
Where might this hood be used in practice?
It may be used in industrial electronics, multi-channel controller boards, interface modules, and OEM devices using 11-pole pluggable PCB connectors.
