Molex MultiCat Mid-Power Connectors

Molex MultiCat mid-power connectors with precision-machined contacts

Molex has designed the W-to-W and W-to-B MulitCat Power Connector with a locking mechanism that is both compact and lightweight, easing OEMs’ design constraints.

Molex MultiCat Mid-Power Connectors

Currently, locking mechanisms on many wire-to-wire (W-to-W) and wire-to-board (W-to-B) power connectors are metalized, increasing the connector size and weight. This creates difficulties for designers dealing with size and weight constraints in many applications, including drones and industrial automation. Molex has designed the W-to-W and W-to-B MulitCat Power Connector with a locking mechanism that is both compact and lightweight, easing OEMs’ design constraints.

In highly competitive markets, cost-conscious OEMs are looking for ways to reduce production costs. The MultiCat Power Connector locking mechanism is not metalized, unlike other power connectors currently on the market, making it the more economical choice. Additionally, its positive lock and CPA actuation make assembly easier, reducing costly errors and reducing assembly time.
