As electronic devices continue to evolve toward higher performance and smaller form factors, maintaining stable power and signal connections within extremely limited internal space has become a major design challenge for many engineers. In recent years, devices such as edge AI equipment —which perform AI processing locally on the device rather than relying on the cloud —along with industrial IoT devices, mobility systems, and  wearables, have rapidly grown in number. These trends place even greater emphasis on the need to balance high-speed operation with space efficiency.
In response to these industry demands, Yokowo has developed a new waterproof two-piece connector.


​​​​​​

[Introducing the Compact Waterproof Two-Piece Connector — Now 20% Lower in Height]

Yokowo has reduced the height of the highly regarded Waterproof Two-Piece Connector by approximately 20%, and sample shipments will begin in March. While originally developed for mobile device battery-pack connections, this new model is designed for a much broader application —including edge AI devices, IoT systems, mobility equipment, and wearables —achieving both space-saving design and high reliability.
 

[Compact Size, Same Outstanding Durability]

The connector uses a two-piece structure consisting of a plug and a receptacle. Yokowo’s proprietary two-point floating contact structure ensures excellent resistance to vibration and shock, enabling stable performance even in harsh environments.
In addition, the receptacle features our patented contact shape, which absorbs ±0.3 mm of misalignment during mating. This provides flexibility during assembly in tight spaces and helps accommodate variations in mass production.​​​​​​

[Key Specifications]

Test Item Specification Conditions
Rated Current 12V / 3A
Contact Resistance 30mΩ Max.
Insulation Resistance 1000MΩ or higher DC500V, 1 min
Dielectric Strength Leak current ≤ 3mA AC500V, 1 min
Durability 2,000 mating cycles Contact resistance ≤ 60mΩ
Waterproofing 1.5m immersion, 30 min No water ingress
Environmental Resistance Same as previous model

Despite its significantly lower profile, the connector maintains the same waterproof and environmental performance as previous models —contributing to greater design flexibility, lighter devices, and optimized internal layouts.
