Highest Quality of Signal Integrity
Improve Damping. Suppress Resonance and Noise (EMC)

To achieve high-speed transmission, in addition to controlling impedance by adjusting the material, shape, and dimensions of the connector, our TSL series suppress resonance by adjusting ground termination and route of transmission.

Highest Quality of Signal Integrity. Improve Damping. Suppress Resonance and Noise (EMC)

The effective mating length, which is related to contact reliability, is set at 0.5 mm to reduce the infiltration of the insert part.
The stub length design, which is related to transmission characteristics, is also optimized to improve damping.

TSL Insert Part

Multi-point ground to suppress noise (EMC).

  • The right angle type (TSL00-31L) has 24 ground points, and the straight type (TSL00-31S) has 15 ground points
  • Multi-point spring contact is used for the ground between connectors.

*Right angle type (TSL00-31L) is shown in the example below.

Case Studies


The data transmission speed of the customer’s legacy cable harness was insufficient, and connection failure due to vibrations occurred.


The customer’s problem was resolved by replacing their legacy cable harness with our TSL Series. Its 32 Gbps transmission met the speed requirements while the lock mechanism protected the connection from vibrations.
