How To Repair Lionel. Rotary B Econ

By the express information you lot give and the (not too great) photo, it seems it is a mechanical encoder, non an optical one.

You don't requite whatsoever information about the equipment it is mounted on, but xv years of continuous operation may be quite a lot for a mechanical encoder. Probably the contacts have worn out and there is no reliable manner to fix them using any sort of chemical.

Best course of activity is to replace it with a new i. The cheapest crappy encoder you tin can buy on ebay (~i$) could work meliorate than your worn-out encoder, at least for a while.

Of course that is not a suggestion for a long-term prepare. If y'all care nearly the equipment, you lot could probably notice a suitable replacement on whatever major component distributor (digikey for example, or RS components), for a couple of dollars.

Just for example, I just did a quick search on digikey trying to detect something vaguely similar: BOURNS PEC11L Serial - 11 mm Low Profile Encoder (datasheet).

Every bit you tin see from this datasheet excerpt (emphasis mine):

the expected minimum encoder life is 100k full rotations. Assuming (optimistically) that the average life is twofold (200k rotations) and that the shaft is rotated on boilerplate l times a twenty-four hours (not uncommon in a command console in a piece of work environment) you get 4000 days average life, i.due east. virtually eleven years. Therefore what I initially said almost your encoder being at its end of life, is perfectly reasonable.

All this assuming information technology is not some specialized high-reliability encoder.

If you want amend communication post more information on that encoder (model number, better photos, info nearly the equipment, etc.).
