Remarks

1. All dimensions are in mm.

2. General tolerance ±1mm.

3. Elucidation:  1:+5V  2:OV  3:V0UT

Directions for use

1. When the current will be measured goes through a sensor, the voltage will be measured at the output end. (Note: The false wiring may result in the damage of the sensor)

2.Custom design in the different rated input current and the output voltage are available.
