Dynamic Research Linear Encoder Scale ~10" Travel LX2A-0010-DC-L15Z920LX2A-0010-DC-R15 As you see, I have two of these encoders, they came from the same system so I assume they are identical spec, but they have different part numbers. If you buy both you get both, but if you buy one, you choose which one to receive. The encoder is in good shape, but the dust repellent plastics are torn due to age probably. Nothing functionally bad, but the plastics are just torn. Item is guaranteed to be in working condition. Disclaimer: All my encoders are professionally removed, stored and shipped. The connector, wiring, or termination is as pictured. Sometime the same part number may have a different terminating connector. Buyer to make sure they know how to use these encoders or they can secure proper connector, and assumes responsibility to find the pinout of the cables.
