Product Description

B102T series current sensor is a closed loop device based on the measuring principle of the hall effect and null balance method,

 with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC, AC or pulsed currents.

1. All dimensions are in mm.

2. General tolerance ±1mm

3. Elucidation:  1:+15V  2:-15V  3:I0UT

 

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.
