The housing color is white. We are considering further variations such as black, red, and blue in the future. Please contact us if you would like to know more details.

We have developed a new type of the "DT Series" high-speed transmission compatible 0.5mm pitch floating connector with a stack height of 25mm. This time, we developed a plug-side connector with a stack height of 15mm and combined it with a receptacle-side connector that has a 10mm increased stack height, achieving a total stack height of 25mm. Similar to the 30mm stack height version, it ensures a high floating amount of ±1.0mm in the XY direction, enabling high-speed serial transmission equivalent to 8Gbps. We will develop seven variations with pin counts ranging from 30 to 140 pins. Additionally, by combining it with the existing DT series receptacle side, it can accommodate the 15mm stack height version. *The 15mm type supports a floating amount of ±0.5mm.

The TSL series is a next-generation harness that enables differential high-speed transmission of 32Gbps with a harness length of 1,000mm (see Photo 1). With a 0.55mm pitch and 31 pins, it allows for a transmission of 320Gbps using 10 differential pairs (AWG#32 coaxial wiring with 20 wires). Another feature of this series is that by combining it with the high-performance coaxial cable "RUOTA" from Tokyo Special Cable Co., Ltd. (TOTOKU), it achieves low loss and low skew. *"RUOTA" is a registered trademark of Tokyo Special Cable Co., Ltd. Registration No. 5594596. Additionally, our company guarantees the quality of the harness products. The harness assembly is performed at our designated factory, and we conduct a thorough inspection of all units before delivery, ensuring you can use it with confidence. Furthermore, this series features a good locking structure with a click feel. The connector has a pull tape, allowing for easy unlocking and removal by pulling the tape, thereby improving work efficiency. *This series is offered as a harness product, so the plug-side connector (TSL21-31S) is not available for individual sale.
