B-JSM Series
Applications featuresThis product is one kind of absolute electro-optical encoder, it can survey the angular displacement, and can possess measures the result by the natural binary output form output, therefore, widely applies in the automated survey, systems and so on automated control, for example: The rotary system numerical control tool rest and so on, this product may substitute the import the similar products.
Features
This encoder for the absolute axial angle encoder, uses the special electronic component, antijamming ability.
In this encoder structure uses dustproof, moisture-proof and so on measures, bears the impact, bears the vibration, the volume is small, the weight is light
This encoder has the strong belt to carry ability.
