FAQ What is the difference between an NPN and a PNP output on this sensor? An NPN output (like on the FL2-20B6H-L2) sinks current, meaning it connects the output line to ground (0V) when an object is detected. A PNP output sources current, connecting the output line to the positive supply voltage (+V). Your PLC or control device input must match the sensor’s output type. Can this sensor detect non-metallic objects like plastic or wood? No, this is an inductive proximity sensor. It operates by generating a high-frequency electromagnetic field and can only detect metallic (conductive) objects that disrupt this field. For non-metallic objects, you would need a capacitive proximity sensor. What does the ‘H’ in the model number FL2-20B6H-L2 signify? The ‘H’ indicates that this is a high-frequency oscillation type sensor. This design helps to prevent mutual interference when multiple sensors are mounted close together, ensuring more reliable operation in dense sensing applications. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
