TSL series was developed as a next-generation coaxial harness that supports high-speed transmission in response to new AWG#36, 500mm technological innovations such as 5G IoT AI with the development concept of "NeGSSUC = Next Generation Super Speed Micro (μ) Coaxial Connector".
<Development concept “NeGSSUC">
In order to maximize the performance of the connector, high-performance 32Gbps high-speed transmission was achieved by using a high-performance coaxial cable "RUOTA" manufactured by Totoku Electric Co., Ltd., which has little attenuation and delay.
In high-speed transmission, the quality of the cable assembly is said to affect its performance.
KEL processes harnesses at designated factories and performs 100% inspection at KEL factories, so we can provide harness products that guarantee high-speed transmission.
TSL series is a product that takes full advantage of the high-speed transmission technology that KEL has cultivated so far and is responsible for the next generation of interconnection.

1. 32Gbps differential high-speed transmission enableTSL series is a next-generation harness with a harness length of 1,000 mm and high-speed differential
transmission of up to 32 Gbps.
0.55mm pitch, 31 pins, 10 differential pairs (20 coaxial AWG # 32 wires), and 1 harness enables
320Gbps transmission. High-speed signal support is realized by low loss and low skew.
2. Signal integrity design

▶Reduction of infiltration of insert parts and minimum design of stub parts.
insert part is reduced. Stub length, which affects transmission characteristics, is also
The right angle type (TSL00-31L) has 24 ground points, and the straight type (TSL00-31S)
▶Multi-point ground design >>Noise（EMC）measures
has 15 ground points. A multipoint spring contact is used for the ground between the
connectors. The figure below shows the right angle type (TSL00-31L).
3. Combination with high-performance coaxial cable (RUOTA)*Low loss and low skew can be realized by combining with high performance coaxial cable

▶Cable length and bit rate guidelinesHarness length is compatible with 100 to 6,000mm. Please contact us if you want a shorter
or longer harness length. Recommended coaxial cables are AWG # 32 and AWG # 36.
TSL series is guaranteed as a harness product, so you can use it with confidence.
▶High quality as a harness product
Harness processing is performed at the factory designated by KEL, and all parts are
inspected by KEL before delivery.
If the length of RUOTA AWG # 32 is up to 1,000mm, the skew in the pair is guaranteed to
▶Skew / phase change due to cable bendingThe following is the result of skew measurement due to cable bending.
It can be used without problems even in small equipment.
4. Variations that expand design possibilities / Pin assignment
▶VariationThe connection method supports vertical connection and horizontal connection.
The straight type (TSL00-31S) has a suction tape and supports automatic mounting.
▶Pin assignmentFor AWG#32, 20 coaxial connections are possible with 10 differential pairs, and for
AWG#36, full connection (31 coax) enable.
