Weidmüller 1005320000 BCZ 3.81 AH07 BK BX for 7-Pole PCB Plug-In Interfaces
The Weidmüller 1005320000 BCZ 3.81 AH07 BK BX cover hood is a family-specific accessory designed for PCB plug-in connector assemblies that need a matched, protective outer component. In practical device design, accessories like this help turn a bare connection point into a more structured and service-friendly interface. That can matter in production, field service, and even day-to-day product handling.
Weidmüller lists the Weidmüller BCZ 3.81 AH07 BK BX hood as a black cover hood for PCB plug-in connectors in the OMNIMATE Signal BC/SC 3.81 series. It is designed for 7 poles, with a 3.81 mm pitch, box packaging, a specified cover screw torque of 0.4 to 0.5 Nm, and a net weight of approximately 4.93 g. The product is also listed as compliant for RoHS and without REACH SVHC above 0.1 wt%.
Why Seven Poles Change the Accessory Choice
The Weidmüller 1005320000 BCZ 3.81 AH07 BK BX 7-pole hood exists because PCB connector accessories are inherently dimensional. As pole count increases, connector width changes, and the hood has to follow that format precisely. In a 7-pole interface, a matched hood helps preserve fit, screw alignment, and a coherent connector outline.
This is not just a packaging detail. It affects how easily the connector can be assembled, accessed, and handled throughout the product’s service life.
Where It Sits in the OMNIMATE Signal Portfolio
The Weidmüller BCZ 3.81 AH07 BK BX connector hood belongs to the BC/SC 3.81 family in the OMNIMATE Signal range. That family uses a 3.81 mm pitch and a standardized connector/accessory logic that allows precise matching between the connector body and the relevant add-on components. For design engineers, that means fewer uncertainties when building a repeatable PCB connection concept.
The specified tightening torque range of 0.4 to 0.5 Nm also reinforces that this accessory is intended for controlled installation rather than informal assembly. That supports quality assurance and repeatability in both prototyping and production environments.
Mechanical Value Beyond Protection
The Weidmüller 1005320000 BCZ 3.81 AH07 BK BX black hood protects the connector area, but that is only part of its value. It also supports a more complete connection interface and can improve handling confidence when connectors are plugged, unplugged, inspected, or serviced. In tightly packed products, that kind of mechanical clarity can reduce errors and make device interaction more intuitive.
For manufacturers, those benefits often translate into better usability and a more refined product impression, even though the part itself is quite compact.
Common Applications
A Weidmüller 1005320000 BCZ 3.81 AH07 BK BX cover hood fits well in industrial controllers, interface electronics, building systems, compact signal processing devices, PCB-based I/O modules, and OEM equipment using 7-pole pluggable connectors in the BC/SC 3.81 ecosystem.

Weidmüller 1005320000FAQ
What is the Weidmüller 1005320000 BCZ 3.81 AH07 BK BX designed for?
It is designed as a cover hood for a 7-pole PCB plug-in connector in the OMNIMATE Signal BC/SC 3.81 family.
Why is the 7-pole version important?
Because the hood must match the exact width and geometry of a 7-pole connector. Pole count directly affects fit and mechanical compatibility.
What does the black housing indicate?
It identifies the hood color and supports consistent product appearance within the connector family. In some designs, it also helps maintain a uniform visual coding strategy.
What torque should be used on the cover screw?
The specified torque range is 0.4 to 0.5 Nm, which supports repeatable assembly quality.
Is the product environmentally compliant?
Yes. The official product data lists RoHS compliance and indicates no REACH SVHC above 0.1 wt%.
What types of devices use this hood?
Typical examples include industrial electronics, interface modules, compact controllers, and OEM PCB-based systems using 7-pole pluggable connectors.
