Weidmüller 1003040000 HDC HQP ALU Bulkhead Housing Guide
The Weidmüller 1003040000 HDC HQP ALU bulkhead housing belongs to the RockStar® HQ heavy-duty connector family and is designed for industrial connection points that need reliable mechanical protection in compact spaces. In many facilities, engineers search for terms such as heavy duty connector housing, bulkhead housing, IP65 industrial connector enclosure, and Weidmüller HDC HQ housing because enclosure quality directly affects connector life, environmental resistance, and maintenance planning.
What the Weidmüller HDC HQP ALU Is Designed For
The Weidmüller HDC HQP ALU is a bulkhead housing in size HQ. It is built as a lower-part feed-through housing with a side-locking clamp on the lower side. This configuration is useful when a secure fixed interface is needed on panels, machine walls, or control cabinet structures. The housing is rated IP65 in the plugged condition, which makes it relevant for industrial environments where dust and water ingress protection matter during operation.
Key Technical Characteristics
From a technical standpoint, the Weidmüller 1003040000 HDC HQP ALU bulkhead housing uses a plastic main housing material and a stainless-steel locking element. It has no cable entry, which matches its role as a bulkhead interface rather than a cable-entry hood. The housing is listed with UL 94 V-0 flammability, an NBR sealing concept, and a compact format with approximately 46.3 mm total length, 29 mm width, and 20 mm housing height. The product is also identified as not suitable for ModuPlug®, which helps narrow correct system matching during specification work.
Why This Bulkhead Housing Matters in Industrial Installations
Bulkhead housings often look simple on paper, but they play a strategic role in machine connectivity. A fixed panel interface supports orderly cable routing, predictable service access, and better protection of mating inserts. In automated production, logistics equipment, process installations, and machine building, a well-matched bulkhead housing can reduce unnecessary stress on connector interfaces. The Weidmüller HDC HQP ALU bulkhead housing is especially relevant where users want a compact HQ-format enclosure with dependable side-locking and consistent environmental sealing.
Practical Installation Considerations
Weidmüller specifically notes that, during mounting, the flat gasket must be correctly seated. That detail matters because sealing performance depends not only on the enclosure rating but also on correct installation practice. In real-world use, issues like uneven mounting surfaces, over-tightening, and poor gasket placement can compromise ingress protection long before the housing itself becomes the limiting factor. This is one reason why experienced engineers often treat enclosure installation as part of the connector system design rather than as a final assembly afterthought.
Where the Weidmüller 1003040000 HDC HQP ALU Fits Best
This model fits projects where a Weidmüller 1003040000 HDC HQP ALU bulkhead housing is needed for compact heavy-duty connector interfaces in machinery, cabinet walls, test equipment, transport systems, and modular production units. Because it is a panel-oriented housing without cable entry, it suits designs where cable routing is managed elsewhere and the panel interface needs to remain mechanically stable and easy to service.
For engineering teams comparing HQ-format housings, this product stands out because it combines a compact form factor, side-locking construction, IP65 performance in use, and a straightforward feed-through design.

Weidmüller 1003040000 FAQ
What type of housing is Weidmüller 1003040000?
It is a bulkhead housing designed as a lower-part feed-through enclosure in the HQ size. That means it is intended for fixed mounting on a panel or wall where a stable connector interface is needed.
Is the Weidmüller HDC HQP ALU suitable for dusty or wet environments?
Yes, in the plugged condition it carries an IP65 protection rating. In practical terms, that makes it suitable for many industrial environments where protection against dust and water jets is important, provided it is installed correctly and used with matching components.
Does this housing include a cable entry?
No. The Weidmüller HDC HQP ALU is specified with no cable entry. That is consistent with its role as a bulkhead housing rather than a hood for top or side cable entry.
Weidmüller 1003040000 What material details are important for this product?
The main housing material is listed as plastic, and the locking element is stainless steel. This combination supports corrosion resistance at the locking point while keeping the housing compact and application-friendly.
Why does gasket positioning matter during installation?
Because the sealing performance depends on proper assembly. Weidmüller notes that the flat gasket must be correctly seated during mounting. If that step is overlooked, the real-world sealing result may fall below the intended design performance even when the correct housing is selected.
