Cables
Endevco designs and manufactures its own cables and connectors
specifically for dynamic testing. In these tough and challenging
environments, accuracy depends as much on cables and connectors
as it does on transducers. Our engineers are well schooled in all the
critical parameters in cable and connector designs that can affect
signal transmission. As a result, these parameters are carefully
optimized in our products to ensure data quality and reliability.
When it comes to this kind of in-house custom capability, ordinary
commercial cable and transducer companies just don’t compare.
Endevco also specializes in custom cables, cable lengths, and
connectors. Please contact your local Endevco representative or
contact the factory directly to discuss your custom requirements.
Mars exploration rover
Endevco cables are used to test Mars exploration
probes but the low-noise flexible design allows for
a variety of test applications. Endevco’s low noise
cables (3090C) provides the critical link between
the sensor and data acquisition. Our proprietary
cable treatments eliminate virtually all unwanted
tribo-electric noise associated cable flex.
