Frequently Asked Questions
What pole pitch accuracy can you achieve?
Standard tolerance is ±0.5° cumulative, with higher precision available for specific designs.
Are your rings compatible with specific sensors (TI/Infineon)?
Yes, we design magnetics to match the sensitivity and signal requirements of all major Hall/MR/GMR sensor ICs.
Do you have stock encoder rings?
We primarily manufacture to customer specifications (make-to-order) to ensure optimized performance for your sensor layout.
How do I specify signal amplitude requirements?
Provide your air gap and sensor sensitivity; our engineers will calculate the required magnetic flux density.
Can you provide the ring + housing assembly?
Yes, we offer full vertical integration including plastic overmolding or metal housing assembly.
