In industrial wiring and equipment protection applications, the sealing reliability and installation adaptability of bulkhead interfaces are often critical challenges. To address this, WAIN introduces the W Series bulkhead connector housing, providing a structurally robust and installation-flexible standard solution for cable entry and exit sealing in control cabinets and equipment enclosures.
1
Design Features: Extended Structure for Dual-Side Protection
The W Series adopts a longitudinally extended bulkhead design, where part of the housing extends into the interior of the cabinet, allowing a cable gland to be installed at the inner end.
This structure ensures that both the exterior and interior sides of the enclosure achieve the same level of sealing and protection, preventing internal exposure to condensation, dust, moisture, or mechanical interference. As a result, connection stability is improved throughout the entire product lifecycle.

Front and Rear Installation Options for Different Assembly Conditions
The main body of the W Series bulkhead housing features a symmetrical front-and-back structure, supporting two installation methods:
●Front-panel installation (fastened from outside the cabinet to the inside)
●Rear-panel installation (fastened from inside the cabinet to the outside)
Users can select the most convenient installation direction based on cabinet structure, cable routing direction, and available working space—without modifying the wiring layout due to structural constraints, significantly improving assembly flexibility.

Gasket Retention Design: Adhesive-Free, Removable, and Reusable
The sealing gasket is secured to the housing using a snap-fit geometric retention design, eliminating the need for adhesive bonding. Key advantages include:
♦The gasket remains securely in place during installation, reducing the risk of misalignment or detachment
♦Tool-free removal without damage, allowing repeated installation or replacement
♦ The gasket is double-sided and reversible, fully compatible with both front and rear installation orientations
This design balances assembly efficiency with maintenance convenience, making it ideal for applications requiring commissioning, replacement, or future expansion.

Models and Sizes Covering Common Wiring Requirements
The W Series bulkhead connector housing is available in multiple sizes, including 6B, 10B, 16B, and 24B, to accommodate different cable quantities and wire diameters.
Users can select the appropriate housing size and thread interface based on actual cable count, cable diameter, and insert specifications.
