This is a Lerner Linde encoder model with a special pulse count of 2500 ppr. The encoder model number is: 861900134-2500, code: 1041986-01. This encoder is relatively rare, and it's rare to still see it in action.
This time the customer was a wind power maintenance unit that came in to inquire about a custom replacement for this encoder. Customization is no problem, last year did three 2500 pulse customers, all wind power industry. This is a product more troublesome, all from scratch. The code disk is not commonly used code disk, need to re-engrave. Electrical part, this encoder voltage is still 5V.
Therefore, there is no way to customize this encoder in quantities of three or two. All materials need to be available, and it is extremely uneconomical for us to have too small a quantity. This series of 2500 pulse encoders can be customized from a minimum of 10 units.
Introduction to Customized Alternatives
Our custom replacements are almost identical to the originals, even the color is basically the same, only the brand and model number are different. Our customized products have counterpart models, that is, a custom encoder made from a certain model we will give it a new model number.
One thing that makes this encoder product different from most is that the voltage is 5V. most 861 encoders support 10-30V, this one is 5V and the electrical part needs to be re-paneled.
The picture above shows our finished product.
We are targetingLinde 861Various encoder replacements have been developed, basically all 1:1 solutions. These encoders are mostly used in the wind power sector, but unfortunately a number of models have been withdrawn from production or upgraded, leaving a number of models without replacement parts. For example, for this 2500 pulse product, Linde has several similar models that have been discontinued, making it difficult for end customers to purchase.
For such discontinued models, the ideal way to customize them at present is to use a 1:1 solution. This has been the most popular option in the wind power sector in recent years. After all, replacing and testing a new encoder requires more time and cost, and a direct replacement is the least expensive replacement option for the maintenance organization. In this way, most people can operate the replacement.
As I recall from this blog this is the third version of the 2500 Pulse product. With the passage of time, this type of incomplete product will probably never be officially released again, and all three known models have been discontinued. This will put a lot of pressure on the demand for spare parts at a later date. But overall speaking, the overall demand for spare parts is not much, so there is no way to stock stock, can only have this non-standard form of customization.
