The FG4SS-1200G-90G-NG, a model from Hubner, has likely been around for over 20 years, with data suggesting it was released in 2001.
Due to the superior quality of this encoder, it has been able to serve reliably in various industrial scenarios for many years. It is only in the past couple of years that inquiries about alternative solutions have begun to emerge
When dealing with this encoder, there are several key points to note:
Firstly, the shaft diameter, which comes in sizes 11mm and 14mm. You cannot confirm the shaft diameter from a mere photo of the exterior, which is crucial. Unlike newer products that indicate the shaft diameter in their model number, this information cannot be verified.
Another aspect is the plug connection method; it is essential to understand the pin configuration. The most ideal approach is to send the original part for inspection to define each pin. Then, a solution can be provided. Of course, for this model, we have already determined the wiring method and pin definitions.
Although we have conducted basic tests, it is safer to confirm if dealing with products from different eras.
If you encounter a non-functional FG4SS-1200G-90G-NG encoder and are unable to purchase one, you can contact us to explore alternative solutions to address application issues.
Regarding older models, as long as there are inquiries about alternative solutions, we will take the time to post them on our website to assist as many people as possible. The main issue is that it is difficult to purchase outdated models, and since the machinery is still operational, some customers prefer not to switch to other products and are in need of the "original match."
