Features and Benefits

Four types of physical keycap alignment and color‑coding error‑proofing
The W01 product features four physical key‑positioning detents, with each keycap color‑coded to ensure that even when multiple connectors with the same pin count are plugged in blindly, misalignment is impossible. This significantly enhances user error tolerance.

CPA Design: During the product assembly process, the relatively high ambient noise in the factory often makes the standard click‑to‑lock sound difficult for workers to detect. The CPA design of the W01 ensures proper mating of the connector, preventing looseness or disconnection that could result from incomplete insertion. Additionally, the CPA significantly enhances the retention force after mating, thereby improving the overall structural integrity of the connector.

A variety of coating options
The W01 is available in both gold-plated and tin-plated versions, enabling customers to strike an optimal balance between cost and performance across diverse application scenarios, thereby broadening their range of choices.
