18 Mile USB Cable! By: Ronald Nelson October 08, 2015, 0 Comments

[In the industrial environment, cables are often routed in cable trays or bundled along with existing cable harnesses necessitating the need for a longer length of sensor signal cable. Rarely can cable be run direct point to point along the floor due to both the trip hazard and likely damage to cable. A cable stretched taut across the facility presents a very real problem.] When it comes to the Digiducer’s USB Accelerometer, folks are less worried about tripping and more concerned about signal integrity that transmits the data through the cable. How long can the USB cable be extended without compromising the integrity of the data measurements?

The Model 333D01 provides a nominal 3 m (10 ft.) integrated USB cable. The matter of how far this cable can be extended without losing signal quality depends on the type of cabling extension used. Passive extenders, such as a wire extender, can transmit up to 4.6 m (15 ft.). This makes it possible to extend the Digiducer’s integrated cable up to an additional 1.8 m (6 ft.) before requiring an active extender. Active electrical extenders can be lengthened up to 9.1 m (30 ft.) coupled with the integrated cable. A USB to Ethernet cable allows for further extension. A single mode fiber optic cable will allow the signal to be carried up to 30 km (18.6 mi.)!

No matter the circumstance, if a longer cable is needed, length can be attained.
