Hall Effect gear tooth sensors CYGTS212 are applied to the non-contact speed measurement of rotational gears. The measuring range is 1-20000rpm and the output square-wave signal can be directly connected with TTL, CMOS electric circuits and general tachometers to constitute the tachometric measuring and control systems. The CYGTS sensors use the standard cylinder structure and have advantages of the waterproofing, dustproof, guards against the greasy dirt. They can reliably work in adverse circumstances, specially are suitable for industry control and military applications.

CYGTS212 gear tooth sensors use a magnetically biased Hall Effect integrated circuit to accurately sense rotational movement of ferrous metal gears. This specially designed integrated circuit with bias magnet is sealed in metal package for physical protection and cost effective installation. Thanks to the advanced Hall Effect measurement technology, these sensors can distinguish the addendum and tooth valley of the rotated gear and transform them to a square-wave output signal. Corresponding to a pair of addendum and tooth valley the sensor outputs a period of square-wave signal (namely conversion ratio K=1). The Hall Effect gear velocity sensors can be used to measure gears with a modulus ≥0.5mm.
