Product Description

The Hall-effect sensor accurately track extremely small changes in magnetic flux density—changes generally too small to operate Hall-effect switches. As motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events. As sensitive monitors of electromagnets, they can effectively measure a system's performance with negligible system loading while providing isolation from contaminated and electrically noisy environments. Each Hall-effect integrated circuit includes a Hall sensing element, linear amplifier, and emitter-follower output stage. Problems associated with handling tiny analog signals are minimized by having the Hall cell and amplifier on a single chip. Three package styles provide a magnetically optimized package for most applications. FEATURES . Extremely Sensitive . Flat response to *3kHz . Low-Noise Output . 4.5V to 6V Operation .
