The World Smallest Spring Connector ※1

High Speed Transmission 40GbpsWater proof connector

Yokowo Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, President: Takayuki Tokuma) has developed the"world's smallest SPRING CONNECTOR™ (Pogo Pins)" with a diameter of only φ0.35mm for the firsttime.

Yokowo, will commercialize the first USB4.0 compatible "high-speed transmission 40Gbps

waterproof connector" using this Pogo Pins. Sample shipments will start in October.
The thinnest tube diameter for Yokowo's Pogo Pins until now was φ0.85mm, but the diameter of this
newly developed world's smallest Pogo Pins is about 60% thinner at φ0.35mm. This was made possible
by utilizing one of Yokowo’s divisions that has the manufacturing, know-how of contact probes used insemiconductor inspection jigs, which we’ve combined with our mass production capabilities and costeffective manufacturing methods required for electronic components.
Yokowo has also commercialized the industry's※1 first 40Gbps high-speed waterproof connector using
the world's smallest Pogo Pins. This product meets the strict standards of USB4 by reducing signal
attenuation with the thin Pogo Pins and suppressing noise with a metal housing. In addition, potting
achieves high waterproof performance equivalent to IPX7, and because the Pogo Pin is thin, it is possible
to layout more Pogo Pins in a small space, contributing to the miniaturization of the connector size.
As devices become smaller in various industries, there is a demand for smaller and lighter parts toefficiently use limited space. The newly developed world's smallest Pogo Pin connector maintains theadvantages of easy attachment and detachment of Pogo Pins while achieving more space-saving thanever before, contributing to simplifying our customers' design.
