description the sndh - t series is a d ual differential hall sensor that provid es speed and direction information using a quadrature output with signals 90 phase shifted from each other. target direction is determined by output lead/lag phase shifting. this product is d esigned for applications where extremely high resolution is required at wide frequency ranges, 1 khz to 15 khz, and large air gaps. bic mos (bipolar complementary metal - oxide - semiconductor) hall - effect technology , u sing advanced digital signal p rocessing for dynamic off - set cancellation , provides enhanced air gap performance and phase shift accuracy over most conditions. unique patented (pending) ic (integrated circuit) packaging provides output phase shift tolerancing with enhanced accuracy . the r obust package is automotive under - the - hood grade for most environmental conditions as well as em i (electromagentic interference) hardened. multiple connection options , including wire harness and integral connector versions using amp super seal or amp jr. timer connectors , are available . package design includes an o - ring seal for pressure applications and a fix ed mounting flange. featu res hall - e ffect magnetic sensing technology dual d ifferential hall provides enhanced target resolution advanced perfo rmance dynamic offset self calibration air gap up to 2 mm [0.08 in] near z ero s peed automotive under - the - hood packaging integrity emi hardened high frequency switching capability ( 1 hz to 15 k hz) - 40 o c to 150 o c [ - 40 f to 302 f] continuous operating tem perature multiple connector options short circuit protection reverse voltage protection open collector output low j itter output o - ring seal potential applications steering position tachometers/counters encoders speed and direction of gears and shafts in transmissions, hydraulic motors, pumps, and gear boxes
