Proximity switch -AH-SF12D

    Low power consumption 

    Operation under low-voltage: 2.7V 

    Low current- Dozens of uA of the power consumption current 

    Omnipolar works. Both S, N pole can work 

    Wide temperature range: -45℃ to 85℃ 

    Lead / connector for direct output 

    High sensitivity 

    Customized lead output


The AH-SF12D is an omnipolar low power magnetic proximity switch based on Hall IC for detecting the departure and closing of the object. 

With AH-SF12D, it needn’t distinguish the poles, it only makes the magnet leave or close to the sensor. AH-SF12D has excellent voltage and temperature performance, to ensure that the sensor to stable work in a wide voltage and temperature range, the reverse voltage protection circuit can avoid the reverse voltage damage.
