【产品说明】
True Zero Speed,
High Accuracy, Gear Tooth Sensor
High Accuracy, Gear Tooth Sensor
The ATS665 true zero-speed gear tooth sensor is an optimized
Hall IC/magnet configuration packaged in a molded module that
provides a user-friendly solution for digital gear tooth sensing
applications. The sensor module consists of an over-molded
package, which holds together a samarium cobalt magnet, a pole
piece and a true zero-speed Hall IC that has been optimized to the
magnetic circuit. This small package can be easily assembled and
used in conjunction with gears of various shapes and sizes.

OPERATING CHARACTERISTICS
Valid at TA = -40oC to 150oC over air gap, unless otherwise noted
Typical operating parameters: Vcc = 12 V and TA = 25°C

Typical operating parameters: Vcc = 12 V and TA = 25°C
Maximum Allowable Power Dissipation Calculation for ATS665:
Assume:
Ta = Tamax = 165 °C
Tj(max) = 165°C
4 Icc = 12.0 mA
