These scanners will work with scanners that state "KBW" or "Wedge" on the back label. Some scanner models will also require a power adapter, but I am certain that MS9520, MS9540, MS9535, and MS3580 do not require a power adapter. Please contact me if you want to know if your scanner requires a power adapter or not, and if so, I can include one of these for $5 more if interested.
Here are just a few Metrologic KBW Scanner models that they will work with:
MS9520 Voyager
MS9540 Voyager
MS9535 Voyager
MS7120 Orbit
MS7220 Argus Scan
MS6520 Cubit
MS6220 Pulsar
MS3580 QuantumT
Any other MetroSelect compatible scanner
Please contact me if you would like me to confirm that this cable will work for your scanner model if it is not on the list.
If you are not satisfied with the cable for ANY reason, you may return it to me within 30 days for a refund or exchange. Shipping will be FREE by USPS or UPS ground depending on location and quantity ordered. Thanks for looking and please ask any questions you may have!
