Liteon model numbers



Hi all. I’m wondering if there are any actual differences between the 411s vs 451s or 811s vs 851s? Is one particularly better than the other? To clarify, I know the differences between the 4 series and 8 series but I want to know about the -11 vs -51, if there are any differences between them. Thanks.


The PUH (pickup head) is different. Otherwise they are pretty much identical.

Using that fancy little seach button in the upper right you will see this question has been asked many times before.

Here are a few examples:


Thanks for the info and sorry for repeating an often-asked question. I normally try a search before posting but I wasn’t exactly sure what to search for in this case. Anyway, thanks again.
