During the surge of cabinet integration in smart manufacturing, the footprint of connectors has become a key bottleneck limiting equipment compactness. Traditional latch‑style housings require extra clearance for unlatching, restricting how densely wiring can be arranged. WAIN’s quick‑connect W3A metal housing uses a spring‑assisted latch and a zero‑protrusion unlocking design to compress the installation space and provide the hardware support needed for high‑density deployment of industrial equipment.

 

 

 

Comparison with traditional latch type housings

 

 

No.1

Space usage

The traditional design takes up more room and needs extra space for the latch to open; the W3A is more compact and the built‑in button means no additional clearance is needed when unlocking.

No.2

Sealing

Axial compression sealing on the traditional design offers good protection; the W3A’s lateral radial sealing provides even better protection.

No.3

Ease of use

With the traditional design you must open the latch before you can plug or unplug; with the W3A you simply press the button and push or pull in one step.

 

 

 

Advantages of the W3A quick connect housing

 

No.1

Improved plug/unplug efficiency

✔️ The button integrates both mating and unlatching functions, so plugging or unplugging is a single press‑push/pull action instead of the multi‑step process required by traditional locks.

No.2

Secure and reliable connection

✔️ A limit‑rib design ensures precise insertion and provides mechanical locking force to prevent accidental disconnection, keeping the connection solid.

No.3

Seamless upgrade compatibility

✔️ The panel cut‑out dimensions are identical to those of the existing (latch‑type) 3A housing, so existing panels can be upgraded smoothly to the W3A without modification.

No.4

Comprehensive protection

✔️ Rated IP67, it resists dust and short‑term water immersion;

✔️ Its optimized lateral radial sealing structure delivers excellent sealing and reliable protection.

No.5

Compact, efficient design

✔️ Its very small size and quick‑connect feature make it ideal for dense installation environments such as telecommunications cabinets, control boxes and smart devices.
