1. All dimensions are in mm.
2. General tolerance ±1mm.
3. Elucidation: 1:+5V 2:OV 3:V0UT 4:2.5V
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. Customs can adjust output amplitude of the sensor by needs.
3.Custom design in the different rated input current and the output voltage are available.
