YD62 explosion-proof rotational speed sensor can directly replace the Hall switch, its core component is the use of magnetic resistance as a detection element, is a new type of rotational speed sensor, after a new signal processing circuit to reduce the noise, more perfect function.YD62 has been widely used in various fields. Detecting distance is 4mm, it can detect the small touch teeth which cannot be detected by proximity switches Compared with other types of tooth speed sensors, YD62 has small error in the measured speed, high linearity, and zero speed can be realized; high sensitivity, high reliability, and long service life; long triggering distance, and distance transmission can be realized; strong resistance to magneto-electricity interference; and good shock resistance and vibration resistance.
