Product details
Brief introduction
YD62Explosion proof speed sensor can directly replace Hall switch, and its core component is a magnetic sensitive resistor as the detection element. It is a new type of speed sensor, which reduces noise and has more complete functions through a brand new signal processing circuit.YD62It has been widely applied in various fields. Especially in low-speed or ultra-low speed non-contact detection, it fills the speed measurement range of domestic magneto electric sensors0-20KHZBlank space, detection distance4mmCompared with other types of gear speed sensors, it can detect small tactile teeth that cannot be detected by proximity switches,YD62The measured speed has a small error, high linearity, and can achieve zero speed; High sensitivity, strong reliability, and long lifespan; Long triggering distance, capable of distance transmission; Strong resistance to magneto electric interference; Has good impact resistance and earthquake resistance.
