Weidmüller BCZ 3.81 AH14 BK BX 14-Pole Cover Hood Explained
The Weidmüller BCZ 3.81 AH14 BK BX cover hood is a connector accessory designed for users who need a precise mechanical match within the OMNIMATE Signal connector family. In board-level connection systems, small accessories influence usability more than they first appear to. A hood can improve connector handling, support a tidier installation layout, and contribute to an overall more robust interface design. That makes the Weidmüller BCZ 3.81 AH14 BK BX cover hood especially useful in structured industrial electronics projects.
What Kind of Product Is It?
This product is identified as a PCB plug-in connector accessory, specifically a hood. It is intended for a 14-pole configuration in the BC/SC 3.81 series and is designed for a 3.81 mm pitch. The housing is black and the material listed is PA 66 GF 30, which is a reinforced engineering plastic selected for durability and dimensional consistency.
For designers and purchasing teams, that combination is important because it ties the product directly to a defined connector family, a defined pole count, and a defined installation profile. There is less room for uncertainty when specifying a part that is already precisely aligned with the rest of the system.
Technical Points That Matter
The Weidmüller BCZ 3.81 AH14 BK BX PCB accessory uses a cover screw torque range of 0.4 to 0.5 Nm. It belongs to the OMNIMATE Signal BC/SC 3.81 family, supports 14 poles, and is designed around the familiar 3.81 mm pitch. The product is black and has a listed net weight of about 8.9 g.
Why a 14-Pole Hood Is Worth Specifying Properly
In electronics production, exact pole-count accessories help keep assemblies consistent. A 14-pole hood avoids confusion with 12-, 13-, 15-, or 16-pole variants and makes it easier to maintain traceable part numbers in engineering drawings and ERP systems. That is a practical advantage in procurement and service work, not just in design.
The Weidmüller BCZ 3.81 AH14 BK BX connector hood is particularly relevant where a board connection is expected to be assembled cleanly, documented clearly, and maintained without unnecessary part-identification issues later on.
Design and Application Perspective
Because this hood belongs to the OMNIMATE Signal range, it fits naturally into control electronics, interface boards, signal modules, and compact automation hardware. Accessories of this kind help translate a connector family from a bare electrical interface into a more complete mechanical solution. In many industrial applications, that matters when products are handled by more than one technician across installation, commissioning, and service stages.
From a design perspective, a hood can also support a more finished connector area, which is helpful when multiple wiring interfaces are grouped closely together on a PCB assembly.
Where It Fits Best
The Weidmüller BCZ 3.81 AH14 BK BX cover hood is well suited to industrial controller boards, communication interface modules, compact instrumentation hardware, and panel-related electronics where a 14-pole OMNIMATE Signal arrangement is part of the architecture.

FAQ
What makes the Weidmüller BCZ 3.81 AH14 BK BX different from nearby variants?
The biggest difference is the pole count. This version is specifically designed for 14 poles. In connector accessories, the correct pole count is essential for proper compatibility and clean specification management.
Is this a current-carrying connector?
No. It is an accessory hood for a PCB plug-in connector system. Its primary role is mechanical support, protection, and improved handling rather than electrical conduction.
What series does this product belong to?
It belongs to the OMNIMATE Signal BC/SC 3.81 family, a known Weidmüller connector platform for compact PCB connection applications.
What is the installation torque for the cover screw?
The official product information specifies 0.4 to 0.5 Nm. Following that range helps maintain installation consistency and reduces the risk of mechanical stress during assembly.
What material is used for the hood?
The material is PA 66 GF 30. This reinforced polyamide is commonly chosen for industrial accessory parts because of its balance of strength and practical manufacturing performance.
Where would this hood typically be used?
It is typically used in industrial PCB assemblies
