## **Mechanical characteristics** 

## **Remarks** 

- General tolerance 

 General tolerance ± 0.2 mm • Primary through-hole 12.7 x 7 mm • Fastening & connection of secondary 3 pins 0.63 x 0.56 mm Recommended PCB hole 0.9 mm 

- **I** S is positive when **I** P flows in the direction of the arrow. 

- Temperature of the primary conductor should not exceed 100°C. 

- Dynamic performances (di/dt and response time) are best with a single bar completely filling the primary hole. 

- In order to achieve the best magnetic coupling, the primary windings have to be wound over the top edge of the device. 

LEM  reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
