GTS gear speed sensor is an advanced speed sensor for non-contact detection of rotating body speed, Measuring range is 1 to 20000 rev / min, the output of the square wave signal can be directly and TTL, CMOS, etc. Circuit interface, constitute the speed measurement / control system. GTS products using round pipe waterproof structure, with waterproof, dustproof, anti-oil advantages, can work reliably in harsh environments, especially for industrial control and military projects.
