This is just an example of a specific tailor-made encoder kit, but there can be numerous variations with different interfaces, mechanical, electrical adjustments, etc. The client would have to cover the non-recurring engineering (NRE) cost for designing and manufacturing the encoder kit depending on the complexity of adjustments needed for the application.

Note: Please consult beforehand to confirm specific adjustments and capabilities.
