From pinsto protocols

Using state-of-the-art technology, LEMO
designs, tests and builds customised connectivity solutions, employing our customers’ most stringent requirements as ourguide. From a thorough needs analysis andan evaluation of our customer’s specifications, our engineers and technical advisers
can accompany our customers from thedesign to the delivery of your connectivity
solutions.

By combining in-house cable assemblywith our expertise in connectors andcables, LEMO established integrated
solutions as the standard for connectivity.
We offer comprehensive interconnect
solutions, ensuring optimal connections
between our connectors and suitable
cables. Our certified teams design, build,and test complex cable assemblies, driven
by customer requirements.

In order to ensure that high-speed signals
travel from one device to another without
loss or distortion, special attention needs
to be given to the connector design, cableselection and cable assembly, in order tolimit the effect of insertion loss, attenuation,
return loss and crosstalk. For connectors orcable assemblies requiring unique signal
integrity, LEMO can design, simulate andtest bespoke solutions to meet customers’
specifications.
