1. Size error: ±0.5mm;
2. Lead size: □ 0.64*0.64mm*5, recommended PCB cut-out φ1.2mm;
3. This sensor is used to measure AC and DC voltage by measuring milliampere current;
4. Before use, calculate the current limiting resistance R0 resistance and resistance power between voltages;
5. The installation size should be consistent with the sensor size, and the pins should not be squeezed to avoid an open circuit of the internal pin connection;
6. When performing pin welding, the soldering time should be as short as possible to avoid causing the internal pin connection to be open;


1. Installation dimensions need fit to thesensor size, avoid to squeezing the pin, it would open the internal pin circuitconnections.

2. Recommend mounting aperture of .1.2.

3. Use 30w or less soldering iron for pinwelding and do it as short as possible to avoid internal pin connections open.
