Product Details

The outer diameter is 99mm, and the through hole diameter is 38.1mm. It is suitable for the standard series of integral precision conductive slip rings with an outer diameter of <=38.1mm.<>

* Note:

If an inner hole of less than 38.1mm is required, it can be solved by adding an inne lining bushing.

Note:

N 10A current loops combined can be used as one N*10A current loop.

For example:

Two loops of 10A are combined and used as one route of 20A.

10A and signal (5A) can be combined arbitrarily. For details, please consult customer service.

Non-standard customization is available on standard products. Please consult customer service.
