Why PML?
- Ability to deliver mass production quantities finally pure hydrogen heat treated.
- Carbide Auto stacking tooling used for production on highly accurate imported high speed press.
- Samples for concept testing provided made by low cost prototype tooling or even by wire cutting.
- PML collaborates for current sensor application with Maglab (representative & development Partner) and Melexis. Maglab (representative & development Partner) is an engineering company interfacing the design of the current sensor based on Melexis Hall-Sensors and PML magnetic cores/shields. Melexis is an automotive qualified sensor supplier.
- Dimensions functionally critical like gap & stack perpendicularity, Symmetricity, Concentricity is achieved in tolerance range of 0.02 to 0.04.
- Ability to check the core material in a ring shape or close loop shape by plotting hysteresis loop.
- Ability to test the outgoing core performance at desired current & desired frequency. Frequency can be up to 50 KHz. Hence we can generate simulation as per the actual application.
